A cab driver who picked up three people from Casino del Sol was carjacked and robbed Wednesday.

At about 6:30 a.m., the 54-year-old cab driver picked up a man and two women from the casino at 5655 W. Valencia Road, said Chief Deputy Chris Nanos of the Pima County Sheriff’s Department.

The cab driver was directed to the 2900 block of West Via San Andrea, near South Cardinal Avenue and West Hermans Road, Nanos said.

When he turned down that street, one of the women and the man took out weapons and told the cabbie to pull over and give them his money. The cabbie refused and he was then pulled out of the cab and robbed, Nanos said.

While the cab driver was being robbed, a vehicle passed slowly and the three assailants got back into the cab and drove away, Nanos said.

The cab driver, who was not injured, yelled to the passing motorist to call 911.

Among the two women assailants, one is described as about age 40, about 5 feet tall and weighing 130 pounds. Her black hair was pulled into a bun, and she had a tattoo on the left side of her neck and possibly one tattoo on her arm. She was wearing a black T-shirt and denim pants, and went by the name Monica, Nanos said.

The woman claimed to be the wife of the man, and mother of the other woman involved in the crime, Nanos said.

The other woman was in her early 20s and was about 5 feet tall and weighed 140 pounds. She had brown eyes with painted-on eyebrows, and was wearing a white T-shirt with an unknown print.

The man was described as about 45 years old, and had a deep voice. He was about 5 feet 3 inches tall and weighed 140 pounds. He was wearing a black short-sleeved button up shirt, black pants and a black ball cap.

Anyone with information is asked to call 911 or 88-CRIME.
