Police found a five-gallon gas container on the grounds of a mansion at the center of a dispute between 50 Cent and his ex-girlfriend.
On early Friday morning, a fire ripped through the $2.4 million dollar Dix Hills, Long Island mansion, sending 6 people, including Tompkins and the superstar rappers 10-year-old son, to the hospital.
While arson investigators have yet-to-determine the cause of the inferno that completely destroyed the mansion, officials had already labeled the fire suspicious, due to the intensity of the blaze, which lasted about 45 minutes.
Tompkins, who accused 50 Cent of having a role in the incident, also accused the rapper of not checking on his son Marquise in the incidents aftermath.
"Tell him to call his son!" Tompkins shouted at reporters yesterday when she returned to grounds of the property, where she had been living with their son, her new boyfriend and other individuals.
50 Cent, born Curtis Jackson and the boyfriend were involved in a physical confrontation in the office of Tompkins lawyer during a deposition hearing, just days before the house was destroyed.
The rapper, 32, denied any involvement in the fire and expressed gratitude that no one was serious injured in the fire.
50 Cent and Tompkins will be in Manhattan Supreme Court over ownership of the mansion on June 10.
