TAMPA, Fla. (TBO.com) - At this point, investigators are not looking for suspects after four bodies were found in a horrific Avila mansion fire that authorities said was deliberately set, the Hillsborough County Sheriff’s Office said Thursday.

“This is a very meticulous investigation,” sheriff’s spokeswoman Debbie Carter told The Tampa Tribune. “There is a lot of stuff to go through.”

Detectives were at the house again Thursday. Carter said investigators would be looking at all angles, including the possibility of murder-suicide.

Because of the condition of the house — including fire and water damage — it may take several days to identity the bodies, and to determine what happened, Carter said.

Authorities have not confirmed the identity of the two adults and two teenagers, but a family that rented the home has not been seen since Wednesday morning’s blaze — Darrin and Kim Campbell and their children, 19-year-old Colin and 16-year-old Megan, both students at Carrollwood Day School.

Kim Campbell’s father, Gordon Lambie, told The Associated Press that Darrin Campbell had moved to Tampa more than 10 years ago to take a job with a glass container manufacturer, and held a couple of other jobs before taking the past year off work.

Lambie, who lives in Michigan, didn’t say why he wasn’t working.
