(Scroll down for video) A high ranking police officer in Las Vegas, Nevada, shot and killed his wife, son, and then killed himself, according to police reports in Nevada.
Las Vegas Police are now searching for answers after one of their own killed his wife and son, and called 911 to confess before setting his house on fire, killing himself.
"I cannot think of a reason for this, where something can be so bad that you would like to do this," a senior supervisor of the Las Vegas police Department said on Monday after the murder-suicide.
52-year-old lieutenant Hans Walters served 20 years on the force. His wife, Michelle Walters, was a retired police officer. His son was about seven years old.
They lived in Boulder City, a small community 20 miles from the city, which has a low crime rate.
At 8:20 a.m. on Monday, the lieutenant called 911 and said that he had killed his wife and son, was setting his house on fire and would shoot anyone who approached, a police spokesperson said.
When police arrived, they found the man at the door of the ranch-style house, holding a gun.
"Put the gun down!" Shouted an officer, according to a neighbor.
The man then went inside the burning house, where he apparently killed himself, police said.
Neighbors said the family kept to themselves. There were no details on the work record of the Lieutenant.
A colleague said that he saw him on Saturday night, and the man seemed totally fine. "One wonders how and why this could happen," the officer said.
