A Fort Smith, AR, officer is recovering after having their neck slashed during a domestic violence call this weekend. The suspect was reportedly killed when the officer opened fire.

A woman and the suspect's son were killed at the scene 

Fort Smith Police Chief Danny Baker says the knife attack happened at a home around 6:20 a.m. Sunday, News5 reports.

Officers responded to the area after a neighbor called to report yelling and screaming that they heard and said that there was a man outside assaulting another person on the ground.

Chief Baker says the first Fort Smith officer that arrived on the scene just minutes later was stabbed in the neck by 40-year-old Christofer Conner, identified as the suspect.

Chief Baker said that the injured officer was rushed to an area hospital with a severe laceration to the neck. The officer, who has not been identified at this time, underwent emergency surgery and is recovering.

Baker says Conner was beating a 15-year-old over the head with a rock when the officer arrived. The teen was rushed to a Fort Smith hospital, where he was pronounced dead due to multiple stab wounds and blunt force trauma to the head. The child has been identified as Connor's son.

Another stabbing victim was found dead at the scene. Baker says there was evidence of an "extremely violent attack" inside Connor's home. 42-year-old Julie Moore has been identified as the victim.

Arkansas State Police have taken over the investigation into the knife attack and the officer firing their weapon.
