McCOMB, Miss. -- (WDAM) -- A security guard subdued a man with a knife after he attacked his mother and grandmother in the McComb Social Security Administration building Monday morning.

According to Pike County Coroner Jason Jones, the attacker has been identified 21-year-old Branen Carter and he is dead.

Pike County Sheriff Kenny Cotton said Carter entered a U.S. Social Security Administration office Monday morning and stabbed his mother and grandmother.

Pike County Coroner Jason Jones confirmed that Carter died of a gunshot wound.

Carter was at the Social Security Administration office in McComb with his mother and grandmother. Jones says another relative told him the mother and grandmother had an appointment there and gave Carter a ride. The family came from Foxworth, about 40 miles east of McComb.
