LANCASTER (CBSDFW.COM) – One person is dead and another injured after a shooting outside a restaurant in Lancaster Sunday afternoon. The suspect in the shooting turned himself in.

Police say officers responded to a shooting at an IHOP at 790 Interstate 35E at around 1:50 p.m. When they arrived, officers found two gunshot victims in front of the restaurant.

According to police, a male victim was pronounced dead at the scene while a female victim was transported to a hospital with non-life-threatening injuries.

The male victim was identified by his adopted mother as Mylik Butcher. His mother said he was trying to help his friend out of an abusive relationship when the two were shot by the woman’s ex-boyfriend.

“This kid was actually just trying to diffuse the situation, so whatever level of anger that that gentleman had reached was definitely not worth the consequences he’s going to suffer,” said witness A.L. Owens.

The suspect in the shooting is in custody after he turned himself in to Duncanville police. Police say this was an isolated incident.

Investigation of the shooting is still ongoing.
