Man kills wife, 3 kids in mass shooting; 10-year-old survivor calls 911

A man killed his wife and three of his children in an apparent murder-suicide mass shooting at a home in Oklahoma, according to police.

The only survivor was the 10-year-old son who was asleep during the shootings, Oklahoma City police said. The 10-year-old called 911 Monday morning and said "everyone inside the house appeared to be dead," police said at a news conference Tuesday.

Police said they believe Jonathon Candy, 42, "became involved in an altercation" with his wife, 39-year-old Lindsay Candy, and then shot her multiple times.

Jonathon Candy then "systematically" went through the home, shooting and killing three of their children: 18-year-old Dylan, 14-year-old Ethan and 12-year-old Lucas, according to police.

"Those children were hunted down," police said.

Authorities said they do not know why the 10-year-old was not hurt.
