TAMPA, Fla. (WFLA) — The Hillsborough County Sheriff’s Office is investigating what it called an “apparent double murder-suicide” in Riverview Wednesday morning.

Deputies said they were called to a home on Graham Yarden Drive near Ashton Field Avenue around 6:15 a.m. where they found three people dead.

Sheriff Chad Chronister said the incident began after a 64-year-old man called 911 to report he was in an “impossible situation” and was prepared to self-harm. When deputies arrived at the home, they found the man dead with an apparent self-inflicted gunshot wound.

In fear for the safety of others, deputies entered the home and found two additional people with fatal gunshot wounds. Sheriff Chronister said the man’s 80-year-old wife and stepdaughter, only described as being in her 50s, were both found dead.

Chronister said the stepdaughter was laying in a hospital bed with a feeding tube attached to her.

Deputies said the man’s wife and stepdaughter were both suffering from terminal illnesses.

“It just goes to show you never know what people are going through,” said Troy Quinn, a man who lives right next door.

When asked if there were any previous incidents reported at the home, Sheriff Chronister said there were no red flags.

“He was a great guy. He was a model neighbor,” Quinn said. “He would come out and talk to all the neighbors in the neighborhood and help you out if he could.”

“We have had no previous calls for service at this residence. None of the occupants have any type of criminal history,” Chronister said. “Nothing out of the ordinary that would be a red flag to us.”

A motive has yet to be been determined. The Hillsborough County Sheriff’s Office is investigating.
