Police sources in Tampa identified four people found dead this morning in a raging fire at tennis star James Blake's mansion as Darrin Campbell, his wife Kimberly and their teenage children Colin and Megan. While there was no official confirmation of the victims, public records list Campbell and his family, a well known businessman in the south Florida area, as living at the home Blake was renting out. The four bodies were recovered from the burnt out home, but have yet to be officially identified. The 7,600-square foot home million-dollar home, located inside the exclusive Avila Golf and Country Club north of downtown Tampa, went up in flames around 6a.m. A Hillsborough County Sheriff's spokesman said: 'We have just been given the all clear to go into the property. The bodies are still in there.' Neighbors in the exclusive cul-de-sac also said a family of four lived in the home. Mr Campbell's mother confirmed to MailOnline that her son was living in the home owned by James Blake. Blake, who retired from professional tennis last year, was reportedly at his Connecticut residence at the time of the fire. According to TMZ Sports, the family had been living in the house for a little more than a year and kept to themselves. Both children, Colin, 19, and Megan, 16, attended Carrollwood day school, and the principal reportedly said this afternoon that they will be missed. Guards were posted at the front gate, turning away visitors, Fox 13 reported. According to her Twitter, Megan has just yesterday won an academic award at the school. It's unclear whether the four people found dead in the house were killed by the fire or some other cause. TV reporter Meredyth Censullo, most recently of ABC, tweeted that the victims had 'gunshot wounds to the head.' In a follow up tweet, she cited a source as saying the bodies found in the burning mansion 'had heavy duty fireworks wrapped around their heads.' Darrin Campbell was reportedly found dead on the floor, and Kimberly in a bed. It's not clear where the children were found. Censullo tweeted that several gas cans were found on the second floor of the mansion. Campbell, 51, has held a number of senior jobs with south Florida based companies after graduating from Michigan University. His most high profile position was with P.O.D.S - the company that makes portable storage containers. Based in Clearwater, he was chief executive of the company for just under three years. Campbell, who is originally from Detroit, Michigan, began his career in 1992 at Ford Motor Co, according to an article in the Tampa Bay Times. He worked in various financial positions, principally financial analysis before moving to San Antonio, Texas as chief financial officer for the Pabst Blue Ribbon beer company. In 2000 he relocated to Tampa and joined Anchor Glass Container Co. as senior vice president of sales, leaving as chief executive to join PODS. He later joined Tampa based Ivans Insurance Solutions but left three years ago. A spokesman for the company said they did not believe he had a job to go to when he quit the company. In a 2005 profile of Campbell the Tampa newspaper said he and his wife had their honeymoon at Disney World in Orlando. Campbell said he and his family visited the theme parks in the area about a half-dozen times a year. Officials confirmed they had received reports of gunshots but they said the fire could have set off the rounds. The fire broke out before 6a.m. and Hillsborough County Fire Rescue crews rushed to the scene. Hours later, firefighters were still there putting out hot spots at the home. It could be days before detectives are able to sift through the charred debris, officials said. The cause of the fire is still under investigation, and it is too early to determine if it is suspicious, police said. Blake purchased the home in Avila for $1.5 million in 2005, according to Hillsborough County property records. Neighbors told detectives that Blake hasn't lived in the house for a while and was renting it out, police said. Detectives haven't talked with Blake, whose agent said he was certain Blake was not in Florida. 'He's not in Florida, I can tell you 100 percent that he's not in Florida,' Carlos Fleming told The Associated Press. It had five bedrooms and five bathrooms. Video of the fire showed it totally engulfed in flames. 'It's in the back part of Avila, the million-dollar homes. It's a massive home,' said Nacole Revette, a spokeswoman for Hillsborough Fire Rescue. Pictured below Darrin Campbell and his two children. No picture of wife. This guy had to fuck over some people because this was an execution and whoever ordered it was trying to send a message.
