ST. PETERSBURG, FL – A Florida man, who admitted to stabbing his girlfriend and her mother to death, allegedly had many more victims on his hit list.

Kirk Hysell Jr., 41, is charged with two counts of first degree murder following an incident that happened Saturday morning in St. Petersburg, Florida.

Officers responded to 5252 108th Street North around 10:14 a.m. after a 9-1-1 caller reported a homicide, according to the Pinellas County Sheriff’s Office.

When deputies arrived on scene, they located the first victim, 34-year-old Christina Donzero, dead in a bedroom with multiple stab wounds.

The second victim, 75-year-old Betti “Suzanne” Thevenet Donzero, was found in the garage of the home, also dead with several stab wounds.

Deputies located Hysell in the bathroom of the home with multiple “self-inflicted injuries,” according to police.

Hysell survived and was transported to a hospital.

Detectives say Hysell told his daughter that he had killed his girlfriend and his girlfriend’s mother, which prompted her to call 911.

According to investigators, Hysell admitted to the murders and initially planned to kill the whole family.

He also stated he planned to kill his other family members and if he got out, he would “do it again.”

Hysell remains in the hospital and will be transported to the Pinellas County Jail when released.

The investigation continues.

The defendant in this case is only accused of the charges set forth in the criminal complaint. They are innocent until proven guilty.
