Henderson police have closed the case of a murder-suicide in Boulder City back in January involving a Metro officer, his wife and their 5-year-old son.
Police on Monday released numerous documents pertaining to the investigation, detailing more than 20 interviews.
It was determined that Metro Lt. Hans Walters shot and killed Kathryn Walters, 46, and Maximillian Walters, 5, before turning the gun on himself.
On Jan. 21, Hans Walters called 911 and said he had killed his wife and child and would harm any officer that confronted him at his home.
When police arrived at their home, Hans Walters set fire to the house before taking his life.
Boulder City police on Monday evening released the 911 call Hans Walters made to police before taking his life.
Walters spoke to the 911 dispatcher in a calm voice, explaining that he had shot his wife and child, set his house on fire and intended to open fire on first responders.
"I just shot and killed my son Max and my wife Michelle," Hans Walters told the dispatcher.
"I killed her because she's in such chronic pain from her neck and back. I feel terrible for doing it," he continued.
"I've also set the house on fire. If the fire department comes to my house ... I'm going to open fire on them and then I'm going to shoot myself," he said.
"My wife's in the bedroom - I shot her in the head. My son, unfortunately, is in the living room watching Oswald - I shot him in the head, too," Hans Walters said before hanging up.
