CHARLOTTE, N.C. -- Charlotte-Mecklenburg Police are investigating after a man killed his mother, wife and shot his 12-year-old daughter before turning the gun on himself.

The shooting occurred on the 2200 block of Kilborne Drive at the Woodland Park Apartments around 8:40 a.m. Saturday.

After a brief investigation, authorities said 37-year-old Antioco Andrade Chacon shot and killed his mother, Asuncion Chacon-Perez and his wife, Marina Bravo Aguilar.

"He then shot his 12-year-old daughter," authorities said.

It's been the coldest week of the season but one resident at the Woodland Park apartment complex told NBC Charlotte that the temperature didn't keep him inside today, instead it was the chilling act of murder.

"I'm scared to go to the scare since that happened," said the man.

Antioco was found deceased at the scene from an apparent self-inflicted gunshot wound, authorities said. While he killed his wife and mother, his 12-year-old daughter was transported to Carolinas Medical Center where she was listed in critical condition.

Due to her age, authorities are not releasing her identify.

This is an active, ongoing case. Anyone with information is asked to call 704-432-TIPS and speak directly to a homicide detective.
