Death
On the afternoon of July 6, 2018, Honeycutt's mother called 911 after he had been acting erratically. She said that he had been using nitrous oxide "for six months overseas and I think it scrambled his brain." When police arrived they found that he had barricaded the entrance to his Sherman Oaks home. He fired a shot that hit a wall next to an officer, who fired back at Honeycutt. After several hours, LAPD SWAT entered the home early the next morning, and found Honeycutt dead. Bort Escoto, who coached Honeycutt for four years at Sylmar High School, said that "he was a great kid to be around. But he was having some problems", because in Russia he didn't know the language and the surroundings, concluding that "he was basically having a hard time with the adjustment. I just kept telling him he needed to get out and meet people". An autopsy determined that he committed suicide by a gunshot wound to the head.
