GEORGETOWN An Elgin man accused in the fatal shooting of his girlfriend told police he was playing with a handgun when it accidentally discharged and shot her in the face, according to an arrest affidavit.

Marquis Wilson, 25, was charged with manslaughter, a second-degree felony punishable by up to 20 years in prison.

Police found the body of his girlfriend, 17-year-old Jade Erwin, in the front seat of Wilson’s car near the emergency room entrance of Scott and White Hospital in Taylor on Saturday morning, the affidavit said.

It said officers were told that Wilson and another woman in the car had run away following the shooting. Police later found Wilson and the woman, according to the affidavit.

The woman said Wilson and Erwin had picked her up from her house in Elgin and then stopped at a McDonald’s before going to the County Line Road area in Elgin, the affidavit said.

It said the woman told police that Wilson, who was driving, stopped the car and fired a shot from his handgun into the ground.

She said Wilson then began to spin the gun on his finger and the gun discharged, police said. The woman said Erwin, who was sitting in the front passenger seat, was shot, the affidavit said.

Wilson told police he was driving down a back road when he fired one shot from a .38 handgun out of the car window, said the document.

According to the affidavit, Wilson said he then played with the handgun and it discharged. He said he then realized Erwin had been hit in the face, so he decided to take her to Scott and White Hospital in Taylor, police said.

Wilson said he ran away from the hospital on foot after telling staff that Erwin had been shot, the affidavit said.

He was being held Wednesday in the Williamson County Jail with bail set at $100,000.
