Investigators say Wilson shot and killed his girlfriend, 26-year-old Antoinette Austin shortly before 1:00 p.m.
Investigators say Austin and Wilson were in Wilson's car, fighting. Austin was allegedly breaking up with Wilson. That's when, police say, Wilson pulled out a gun and shot Austin four to five times.
According to police, Wilson pushed Austin's body out of the car and onto the street in the 7500 block of Lansdowne Avenue in the Overbrook Park section of the city. Investigators say Wilson then went to his home on Salford Street.
Police knew Wilson had five firearms in the house, including several rifles which were registered to him. Authorities also could see a suspicious device during the standoff.
Officers arrived there, and began an afternoon-long standoff with Wilson.
That standoff ended around 4:00 p.m. after police forced their way into the home. Wilson was brought out on a stretcher after, investigators say, Wilson shot himself in the face.
Wilson was taken to a hospital in critical condition.
The bomb squad was called to the scene to check out that suspicious device in the house. It turned out to be nothing dangerous.
Because of that standoff, four area schools went into lockdown. The lockdown was lifted around 4:00 p.m. and the students were allowed to go home.
