A man is facing charges after fatally shooting a 16-year-old girl Friday morning at a Cobb County townhouse subdivision, police said.

Officers responded to the 7000 block of Fringe Flower Drive, just north of I-20 and west of I-285, around 9:25 a.m. on reports of a person shot. Alejandro Mario Bencomo Aguilar, 57, was found suffering from a self-inflicted gunshot wound and attempted to stab himself with a knife when officers approached him, Cobb police spokesman Sgt. Eric Smith said.

The teenager was then discovered in an upstairs bedroom suffering from multiple gunshot wounds, Smith added. Despite life-saving measures being provided, officials said the girl was pronounced dead. She had not been publicly identified by Saturday afternoon.

“The offender was in a relationship with the mother of the deceased, and they were all believed to live in the same residence,” Smith confirmed, adding that the mother was not home at the time of the incident.

Aguilar was taken to Grady Memorial Hospital, where Smith said he underwent surgery and is recovering. He is facing charges of murder, aggravated assault and first-degree cruelty to children.

A motive in the case was not provided.
