TAMPA, Fla. (970 WFLA) – Four people found dead in an Avila home have been identified, the Hillsborough County Sheriff’s Office said Thursday.

Deputies said the Medical Examiner's Office positively identified the deceased as the
Campbell family. The family four included 51-year-old Kimberly Ann Campbell, son, 18-year-old Colin James Campbell, 15-year-old Megan Campbell, and 49-year-old Darrin James Campbell.

Colonel Donna Lusczynski confirmed that Darrin Campbell used a Sig 40, purchased in July 2013 from a Tampa store, to shoot his wife and two children in the head. Darrin Campbell then spread the fireworks and gasoline around the house and lit them before shooting himself in the head, according to HCSO.

The fire happened early Wednesday, May 7, on the 16000 block of Sierra De Avila, one of Tampa’s most upscale neighborhoods. Deputies said tennis player James Blake is the owner of the 6,000 square foot mansion, but he was not in the house at the time and was subletting the house to the Campbells.

It took firefighters several hours to put out the blaze the morning of the fire as several areas were smoldering. Since then, detectives have learned that the gas cans were purchased from a local home improvement store on May 4th at 8:00 a.m. and then filled with gasoline at two local gas stations on May 6th.

Detectives continue to interview friends, family members and coworkers to try to find the reasoning behind Darrin Campbell's actions, according to Hillsborough authorities. Detectives did learn one thing about his past. HCSO said detectives confirmed Darrin Campbell had recently taken a few days off from work. A financial audit of Darrin Campbell is also being conducted, deputies said. 

The investigation continues, however, sheriff’s officials said the reasoning behind the tragedy may never be known.
