Man Kills Entire Family and Commits Suicide.

A businessman has shot and killed his wife and two teenage children before setting his house alight and committing suicide.

Authorities revealed four bodies had been found in the burned out Florida house – Darrin Campbell, 49, his wife Kimberly, 19-year-old son Colin and 15-year-old daughter Megan.

They had all been shot in the head with a 40-calibre handgun.

‘This is certainly disturbing,’ Sheriff’s colonel Donna Lusczynski said at a news conference.

Kimberly’s father, who lives in Michigan, said he was shocked to hear of the news because the family was so close.

‘I’ve lost my entire family,’ Gordon Lambie said.

‘It’s very tough right now because I’m 1,500 miles away.’

The Campbells had been renting the million-dollar home, located in Avila, from former US tennis player James Blake.

Investigators are still are trying to figure out what led to the murder suicide and are currently looking into the family’s finances.
