TAMPA, Fla. (TBO.com) - In their search for answers to explain why a seemingly well-adjusted family man killed his wife and two children last month and then set their posh Avila home on fire before turning the gun on himself, detectives got little help from the autopsies, which were released Monday.

Darrin Campbell, who shot each member of his family in the head, was intoxicated at the time, but there were no other substances in his system that may provide a clue as to why he did what he did.

Campbell’s autopsy report said he had a blood-alcohol level of 0.11. In Florida, and most states, people are considered legally drunk with a blood-alcohol level of 0.08 or higher.

Hillsborough County sheriff’s deputies say Campbell, 49, shot and killed his wife, Kimberly, 51, and two children, Collin, 18, and Megan, 16, in the $1.6 million rented home they shared in the exclusive community of Avila before setting fire to the house and killing himself.

The autopsy confirmed that Campbell’s cause of death was a single gunshot wound to the left temple.

The report said he had traces of antihistamine and a cough suppressant in his system and traces of a compound that is produced when smoke is inhaled. No other substances were found, the autopsy report said.

“There’s nothing out of the ordinary,” said Julie Pearson, chief forensic toxicologist with the Hillsborough County Medical Examiner’s Office, which conducted the autopsy. “It was a pretty benign toxicology report. If they are looking for answers to explain his behavior, they will have to look elsewhere.”
