Darrin Campbell “systematically” shot his wife, son and daughter in their rented Avila mansion and then turned the weapon on himself, according to the Hillsborough County Sheriff’s Office.
Investigators had been trying to determine how the family died since the mansion was found burning Wednesday morning. Deputies now say Campbell spread gasoline and fireworks around the home before shooting himself.
The announcement Friday by the Sheriff’s Office leaves the biggest question about the tragedy unanswered – why? Investigators say Campbell had no history of mental health problems and they’re unsure whether financial problems may have caused what they call a murder-suicide.
The weapon used in the shooting was registered to Campbell, who deputies said also purchased about $600 worth of fireworks three days before the fire.
Investigators have developed a timeline of Campbell’s actions going back more than a year.
He purchased a Sig 40 firearm in July 2013 from Shooter’s World at 116 E. Fletcher Ave. in Tampa, deputies said. It's the same weapon deputies said Campbell used to shoot his wife, Kimberly Ann Campbell, 51, Colin James Campbell, 18, and Megan Campbell, 15, in the head before shooting himself.
He bought gas cans May 4 and then filled them up two days later, the day before the mansion was found burning.
Detectives say Darrin Campbell had taken a few days off work recently. In addition to interviewing coworkers, friends and relatives, detectives are having a financial audit performed on Campbell in an effort to find what drove him.
“The investigation continues,” a statement from the Sheriff’s Office says, “however the reasoning behind this tragedy may never be known.”
