Four people were killed in the villa of the former tennis ace

Four people died in a luxury house in Tampa, USA, which was set on fire.

The bodies of the victims were found with bullet holes and traces of fireworks on their heads.

It is a married couple, and the victims were Darin Campbell, his wife Kimberly and children Colin and Megan.

The media also reports that several gas bottles were discovered on the upper floor.

The house is owned by former tennis ace James Blake, but he has been renting it out to a family for the past two years.

The police are investigating whether someone from the family killed their loved ones and then committed suicide, or whether it was a classic murder.
