James Simpkins, a 21-year-old from Detroit, was convicted on three counts of first degree murder in the case of a triple-murder in Flint.
Simpkins' brother 21-year-old Anthony Simpkins, 36-year-old Bobby Jackson and 21-year-old Erica Billingsly were all killed in the attack.
On July 17th, 2012 it was alleged that Simpkins and the others in the home spent most of the day drinking and smoking marijuana.
At one point, prosecutors say, Simpkins entered a bedroom where four people, one of them Simpkins' brother Anthony, was located. Simpkins then opened fire and shot all four people in the bedroom.
Two of the victims died instantly. One man had survived the attack, but was then killed when Simpkins stomped on his head.
Another victim, a 20-year-old woman from Detroit, survived and attempted to fire Simpkins' weapon at him. However, the gun was out of bullets.
The woman and Simpkins then got into a physical fight. The woman had already been shot four times in the groin.
Simpkins first attempted to sexually assault her and then he choked her until she passed out.
On July 18th the victim awoke, severely injured. She climbed out of a window in the home and crawled to a neighbor's house to call 9-1-1.
About five hours later, Simpkins called 9-1-1 himself saying that he was sleeping and then woke up to find his brother and two others dead in the home.
Simpkins now faces life in prison without the possibility of parole. His sentencing is scheduled for February 6th.
