From an article:
Henderson police spokesman Keith Paul said a man called 911 at about 8:20 a.m. Monday and told a dispatcher he killed his wife and child, set his house afire and would shoot anyone who approached.
The home is owned by Hans Walters, according to Clark County assessor records. Many know Walters as a Las Vegas police lieutenant married to a former Las Vegas police officer, Kathryn Walters. The Las Vegas Review-Journal reported that she left the department in 2005.
Boulder City police arrived to find the homeowner with a handgun in the doorway of the burning house before he retreated back inside and apparently killed himself, Paul said.
No shots were fired by police or SWAT officers from Henderson and North Las Vegas who later found the bodies of a 52-year-old man, a 46-year-old woman and a boy inside, Paul said. Officials said the boy was believed to be about 7.
"We're investigating the incident as a murder-suicide at this time," Paul said.
