Tucson police detectives are investigating an apparent murder-suicide after a couple was found dead in a Midtown home.

Officers responded to a "check welfare" call at a residence in the 2700 block of East Copper Street around 6 p.m. Thursday.

When speaking with the property owner, who made the initial call, she told officers an older couple was renting a home and she received a letter instructing her to call police to recover their bodies.

Police found the couple identified as 85-year-old Bill Drake and 71-year-old Margaret Hoyt with obvious signs of gunshot trauma after entering the unlocked residence. 

It appears that Hoyt shot Drake before taking her life, the release said.

Detectives found several notes believed to be written by Hoyt which explained her husband suffered from serious medical conditions. It also detailed what to do with their possessions.

There were signs of foul play, according to the release. The investigation is ongoing.
