A Florida man fatally shot his terminally ill wife Tuesday afternoon and then called 911 to report that he had killed her.

Randall Walton Willis, 61, called 911 at around 12:10pm local time and told an operator that he shot his wife because he wanted to end her suffering, the Hillsborough County Sheriff's Office said in a press release.

Officers arrived at Willis' Tampa home and found him still on the phone with the 911 dispatcher. His wife, 62-year-old Gilda Beth Willis, was dead at the scene.

Randall Willis was taken into police custody, where he told officers he had shot his wife twice, once in the head and once in the chest.

He was booked into jail on a charge of second degree murder with a firearm, the sheriff's office said.

Detectives were investigating Tuesday afternoon and working on obtaining a warrant to search Willis' home.
