Pictured: Husband who killed his wife, three of his four sons, aged 18, 14 and 12 then himself in horrific murder-suicide at their Oklahoma home as orphaned son, 10, survives unharmed

Police believe that a man killed his 'all-American' family before turning the gun on himself in a small community just outside of Oklahoma City.  

Officers found the five dead Monday morning after a fourth son, who is 10, called police to report the shootings, said Sgt. Gary Knight. 

Jonathon Candy, 42, is believed to have killed his wife, 39-year-old Lindsay Candy, and sons 18-year-old Dylan Candy, 14-year-old Ethan Candy and 12-year-old Lucas Candy, Knight said. He says Candy then turned the gun on himself.

'It remains a mystery as to what caused Mr. Candy to murder his wife and three of his children. We don't know' why the fourth child was spared or a motive for the killings, Knight said.

The 10-year-old was placed in the custody of relatives. Police had no previous contact with the family and had not previously been called to their home, he said.

Knight stressed during his first media briefings that the family members didn't die from 'a carbon monoxide situation or anything like that. These are five people who were killed. 

Two of the children, Ethan and Lucas, were students in the Mustang Public School system. Dylan Candy graduated from a local high school in 2023. 

'We are shocked, and our hearts are broken; this tragedy simply defies understanding,' superintendent Charles Bradley wrote in a statement to parents.  

'Nobody expected it, it was very shocking. You know, like I said, they were a great family,' neighbor Brian Graham told KFOR. 

'They were good friends of ours. They would come down all the time and we kind of had hangouts together. We’re really going to miss them. We really wish this wouldn’t have happened,' he added. 

According to his LinkedIn page, Jonathon worked as a video engineer for a company named Cox Media. 

'There are no words to express how heartbroken I am to learn that this unthinkable scene is the beloved Candy family,' a family friend wrote on Facebook. 

'So senseless. The few times I met them seemed like your typical all American family,' a commenter wrote. 

The family lived in a subdivision named Czech Hall Estates in Yukon, Oklahoma, where homes ranged from $211,000 to $365,000.
