The family of actor and comedian Bob Saget filed a lawsuit Tuesday to block the release of certain records related to the investigation into his death, citing privacy concerns.

Saget, 65, was found dead in his hotel room in Orlando, Florida, last month. The Orange County Medical Examiner's Office determined that his death was accidental, most likely due to him falling backward and striking his head.

On Tuesday, Saget's widow Kelly Rizzo and her three daughters filed a lawsuit against Orange County's sheriff and the medical examiner's office, requesting that some investigation records related to the death be exempt from being revealed publicly because of their graphic nature in how they portray the late actor.

"In the process of these investigations, Defendants created records which include photographs, video recordings, audio recordings, statutorily protected autopsy information, and all other statutorily protected information," the lawsuit states. "Upon information and belief, some of these Records graphically depict Mr. Saget, his likeness or features, or parts of him, and were made by Defendants during Defendants' investigations."

The family argues in the lawsuit that the release of this information -- whether through a public records request or any other avenue -- would cause them to "suffer irreparable harm in the form of extreme mental pain, anguish, and emotional distress."

Brian Bieber, a Saget family attorney, told CNN that the injunction was filed to "prevent disclosure of any photographs or videos of Mr. Saget made by the authorities during their investigation."

"The facts of the investigation should be made public, but these materials should remain private out of respect for the dignity of Mr. Saget and his family. It's very simple -- from a human and legal standpoint, the Saget family's privacy rights outweigh any public interest in disclosure of this sensitive information."

CNN reached out to the Orange County Sheriff's Department and the District Nine Medical Examiner's Office for comment on the lawsuit but did not hear back.

The autopsy report showed that Saget had tested positive for Covid-19, though he died from a head injury when he fell in a hotel room in Orlando.

"It is the most probable that the decedent suffered an unwitnessed fall backwards and struck the posterior aspect of his head. The manner of death is accident," Chief Medical Examiner Dr. Joshua D. Stephany said in his report.

According to the report, Saget also had an enlarged heart; 95% blocked on one side. And while there was no alcohol present in his body, his systems contained Clonazepam/Klonopin -- which is taken for seizures, panic disorders and anxiety, the report shows. Additionally, the antidepressant Trazodone was found in Saget's system, the report said.

Wall Street is convinced it's discovered the future of Silicon Valley. But early bets on the "metaverse" are running into some turbulence.

What's the metaverse? It's a virtual world in which people hang out, attend meetings and play games as avatars.

It's generating tons of buzz. But shares of video game developer Roblox, an industry leader, are down 16% in premarket trading on Wednesday after the company's earnings missed expectations.

While average daily active users hit 49.5 million, up 33% year-over-year, bookings — which measures the amount of virtual currency purchased by users to upgrade their avatars — fell short of forecasts.

The platform, which is super popular with kids, has been a go-to for investors looking to get in on the tech industry's push to make the metaverse the next big thing.

In a note to clients earlier this week, Bank of America analyst Omar Dessouky said the metaverse as an investment class "is now like social media at its dawn."

He said Roblox, which had a market value of more than $42 billion as of Tuesday's close, "bears resemblance to a young tech giant," even though it was founded in 2004.

Driving the hype: Roblox has a head start on competitors, which Bank of America expects will be slower to reinvent themselves as metaverse companies. Roblox's control of the technology that underpins its platform, from development tools to graphics software and data centers, allows it to innovate quickly. And in the future, its immersive online world may not just be for children, as Roblox works to build a digital environment — and economy — that's "increasingly engaging and indistinguishable from the real world."

"We think teenagers, and potentially adults, could eventually view Roblox as a multi-purpose platform, similar to how social networks were viewed as such as they grew beyond their core university student demographic," Dessouky said.

That's the promise, at least. But it may require investors to have cast-iron stomachs as more speculative investments take a hit.

Shares of Roblox, which were given a $45 reference price when they made their stock market debut last year, finished Tuesday at $73.30 apiece.

But they've plunged 29% so far this year as Wall Street has soured on the tech sector, which looks less attractive as the Federal Reserve prepares to hike interest rates. Any weakness in earnings doesn't help.

It's not the only metaverse stock to pull back recently. Unity Software, a platform for creating 3D content, has seen its shares plummet 21% this year. They're down another 2% in premarket trading Wednesday.

And Facebook's Meta, which is taking steps to completely rebrand itself as a metaverse-focused company, has plunged 34% this year as disappointed investors note that the pivot could take years to pay off. The company indicated Tuesday it would now refer to employees as "Metamates."

That doesn't mean Wall Street's metaverse frenzy has passed. But at a rocky moment for the market, some of the initial enthusiasm seems to have cooled.

These numbers show why prices could keep rising

44%. That's how much the price of beef and veal rose between January 2021 and January 2022, according to the latest Producer Price Index.

The data, released Tuesday, tracks average price changes that America's producers get paid for their goods and services over time. And it wasn't just meat that commanded a higher premium, including over the past month.

The price of grains was up 22%. Shortening and cooking oils climbed 36%.

Step back: We recently wrote about why fast food chains are expected to keep hiking prices in 2022. Elevated costs for key ingredients — which aren't expected to come down in the near term — are a big reason why.

It's not just food. Energy remains a major sticking point, too, with the price of gasoline shooting up 53% over the past year and diesel fuel gaining 57%. Industrial chemicals remain 31% more expensive over the 12-month period.

Why it matters: Producer prices can be a leading indicator for consumer inflation, since they reflect higher costs that are later passed on to customers. The super-hot PPI reading — which showed overall prices rising 9.7% over the past year — indicates that inflation remains strong.

Markets looked past the data. But it could add to pressure on the Federal Reserve to act decisively at its meeting next month. Investors now think there's a nearly 60% probability that the Fed hikes interest rates by 0.5 percentage points, a supersized intervention.

"Inflation this hot suggests the Fed could kick off their rate raising cycle with a [0.5 percentage point] move," said Lindsey Bell, Ally Invest's chief investment strategist. "That would create significant volatility in stocks."

Work from the mountains? Longer stays boost Airbnb

Airbnb continues to benefit from a rebound in travel and the rise of remote work during the pandemic, as people ditch city life and choose more picturesque spots for home offices.

The company said after markets closed on Tuesday that revenue during the last three months of 2021 reached $1.5 billion, up nearly 80% compared to the previous year and 38% above 2019 levels. It expects a solid start to 2022, and said it's already seeing "strong demand for the summer travel season."

"The fourth quarter was another record quarter and 2021 was the best year in Airbnb's history — despite the global pandemic," CEO Brain Chesky said.

Shares are up 4% in premarket trading.

Airbnb said the impact of Omicron on bookings and cancellations was lower than the company experienced when the Delta variant hit last summer.

It also said customers continue to book longer stays on the platform. Over the past two years, the average trip length has increased by about 15%, according to Airbnb. Stays longer than seven days now account for nearly half of gross nights booked, while stays of 28 nights or more are growing quickly.

"We're seeing that millions of people are not tethered to have to go back to an office five days a week," Chesky told analysts. "And what this means is guests are spreading out to thousands of communities all over the world, and they're also staying longer."

On the radar: As demand jumps, particularly in North America, Airbnb hosts are able to charge more. Average daily rates averaged $154 in the fourth quarter, a 20% increase from the same period in 2020 and 36% above 2019.

Kamila Valieva -- the teenage Russian figure skater at the center of a doping controversy roiling the Beijing Olympics -- had three substances that can be used to aid the heart in her testing sample, according to a report in the New York Times, which cited an exhibit filed in a Sunday hearing by the Court of Arbitration for Sport (CAS).

Two of those substances, Hypoxen and the supplement L-carnitine, are not banned by the World Anti-Doping Agency (WADA), which regulates the use of drugs in international sport. Valieva declared both of these on a doping control form, according to a court application allegedly filed by the World Anti-Doping Agency (WADA) in a case raised after it came to light that Valieva tested positive for a banned substance in December.

The London-based Dossier Center, an investigative website run by an exiled Russian businessman, published part of the WADA court application online and it was reviewed for CNN by Travis Tygart, head of the United States Anti-Doping Agency (USADA). The Dossier Center did not publish the doping control form or the test report exhibited in the case, and CNN has not reviewed them.

CNN has reached out to the CAS and the parties involved in Valieva's arbitration hearing to confirm the validity of the court application published by the Dossier Center and has yet to hear back. CNN has also reached out to the WADA accredited lab in Sweden which tested Valieva's sample from December for comment. Tygart, who is not involved in the investigation into the Russian skater, described the application published by the Dossier Center as "accurate and legitimate."

The 15-year-old skater has been in the spotlight since it emerged days into the Olympics that she tested positive for the banned heart drug trimetazidine, which experts say can enhance endurance. Valieva has sought to blame the positive test on contamination from medication taken by her grandfather, an IOC official familiar with the CAS hearing said on Tuesday.

The presence of the additional substances raises further questions about the skater's drug use, according to Tygart. USADA tried to ban Hypoxen in 2017 due to its performance-enhancing capabilities, but that ban was not implemented, Tygart told CNN.

"It raises a whole host of questions that have yet to be determined and what appears to be the case of a pretty deliberate attempt to use substances in order to enhance performance," Tygart said.

"The picture it paints is, you've got a ​15-year-old. Does she have the wherewithal and the knowledge and the financial resources to find and use two drugs, one of which is prohibited TMZ (Trimetazidine) and another one Hypoxen, [along with] L-carnitine (a supplement) -- to increase endurance and reduce fatigue?," he said.

According to the application published by the Dossier Center, Valieva's mother testified in a provisional hearing that the athlete took one of the substances, Hypoxen, "to treat 'heart variations.'"

Supradyn, which can be used as an immunity boosting supplement, was also listed on Valieva's doping control form, according to the application.

Valieva's positive test for trimetazidine, though taken in December, was only analyzed and reported to Russia's anti-doping agency in February, resulting in Valieva's suspension on February 8 -- a day after she helped propel the Russian Olympic Committee (ROC) to a gold-medal finish in the figure skating team event.

But the skater was reinstated after an appeal, and the CAS on Monday allowed her to compete in the Olympics, citing specific provisions related to her protected status as minor, while investigations into any doping violations by Valieva and the adults responsible for her training continue.

An emotional Valieva came out at the top after the short program of the women's singles competition on Tuesday. She will compete in the second portion of the event -- where she is the favorite for gold -- on Thursday.

Russian athletes competing at the Olympics are already under the shadow of a history of illegal doping: WADA barred Russia from international competitions in 2019 over doping violations. Under the ban set to expire later this year, they've only been able to participate as neutrals in the Games.

The US Centers for Disease Control and Prevention has moved cruise travel out of the "very high" risk category of its travel health notices.

Cruise travel was moved from Level 4 into the CDC's Level 3 "high" risk category on Tuesday, about a week after the agency updated its Covid-19 criteria for evaluating the risk level of cruising.

Cruise travel had been at Level 4 since December 30, when the CDC advised avoiding cruise travel regardless of vaccination status as the Omicron variant surged.

The new Level 3 designation urges travelers to "make sure you are up to date with your Covid-19 vaccines before cruise ship travel."

The agency still advises avoiding cruise travel if you are not up to date with your vaccines or if you are up to date but at increased risk for severe illness from Covid-19.

Cruise industry reaction

Industry body Cruise Lines International Association called the CDC's lowering of cruise travel's risk level "a step in the right direction," in a statement, saying that it "recognizes the leadership and effectiveness of the cruise sector's health and safety protocols that are unmatched by virtually any other commercial setting."

On February 9, the CDC updated its travel health notice for cruise travel by adding criteria for how it determines the risk level for cruises.

For cruise travel, the CDC's primary criteria in evaluating the risk level is the number of new Covid-19 cases among crew and the case trajectory among crew over the past 14 days.

Level 4 means more than 2,000 cases detected among crew on cruise ships over the past 14 days. Level 3 is 1,000 to 2,000 news cases. Level 2 is 500-999 new cases. Level 1 is fewer than 500 new crew cases.

Risk guidance now optional

Meanwhile, the CDC's Covid-19 risk mitigation guidance has become optional for many cruise ships.

The CDC's extended conditional sailing order expired In January, and the agency has transitioned to a voluntary program for foreign-flagged cruise ships operating in US waters.

The agency recently released more information about the new opt-in program. The agency has also updated its cruise ship status dashboard, which shows which ships have opted into its program and a color code indicating the level of Covid-19 detected.

Gas in California hit a record high of $4.72 a gallon on average on Wednesday — and experts say a whopping $5 a gallon will likely be the norm there in a matter of months, if not sooner.

This isn't just an issue for West Coasters: Some of the factors behind the record prices, particularly those related to the switch to renewable fuels, could affect US gas costs nationally in the next few years.

The US national average is currently $3.51 a gallon. Prices in California have long been among the highest, but they've soared in recent years in part because of changes at some West Coast refineries. Facilities have closed in some cases, while others are being modified to refine renewable fuels like diesel made from vegetable oil.

"California is the proxy for what will happen with the energy transition," said Tom Kloza, global head of energy analysis for the Oil Price Information Service, the firm that tracks gas data for AAA. "A number of refineries have closed permanently....Getting people away from fossil fuels might be the right thing to do, but it is not without pain."

So that's one factor: With less refining capacity, the West Coast's previous 2.5 million barrels of daily production heading into the pandemic has plummeted by nearly a quarter.

Kloza thinks $5 a gallon could come to California some point in the second quarter, and perhaps sooner if the invasion of Ukraine by Russia, a major oil producer, comes to pass. Other western states are also feeling the pain, like Hawaii — the only state with an average over $4, at $4.49 a gallon — as well as Washington, Oregon and Nevada, where prices are in the $3.90s.

The switch to renewables affects prices in another way: higher taxes.

California state gas taxes and fees are about 68 cents a gallon, compared to a national average of 39 cents, according to the American Petroleum Institute. California also levies taxes and carbon fees of roughly $1.35 a gallon on wholesale gasoline, a cost that gets passed on to consumers, Kloza said.

"Most states don't have those [wholesale] fees. But it is a coming attraction to a number of blue states," Kloza said. "If you want to move people away from fossil fuels, you have to start charging for carbon."

Meanwhile, California's new record is not only the highest price ever for that state — it's the highest for any state. The next highest record price was $4.70 a gallon in Alaska, but that was set in July 2008, when a spike in oil prices resulted in the record-high national average of $4.11 a gallon.

Though the national US average of $3.51 a gallon is far lower than California's $4.72, the national price is actually rising faster on a percentage basis. Gas prices were up 6% nationwide in just the last month and have climbed 40% over the last year, while By comparison California's is up only 2% for the month and 35% for the year.
