17-year old boy, high on pot, unintentionally shoots self in head and dies

Three young men were smoking pot in Moreno Valley, California.  One of them, 17-year old Miles Meulstee, was playing around with his .357-caliber handgun.  The other boys told him to stop playing around, but Miles didn't listen.  The gun fired, striking Miles in the head and killing him.

From an article:

Alex Barner, 19, said Meulstee, 17, was playing with a .357 that Meulstee owned in Barner’s house Monday.

A third boy named Josh was with Barner and Meulstee at Barner’s house on Mendoza Road in the Sunnymead Ranch area. The parents were not home, Barner said.

“Me and Josh both told him to stop playing around. It’s not a toy,” Barner said.

But the gun fired once, a bullet striking Meulstee in the head, Barner said.
....
“He was kind-hearted, funny, he would do anything for anyone, a great friend,” Barner said of Meulstee. The two of them liked to skateboard together and just hang out almost every day. They lived five houses from each other on Mendoza Road.

Barner and other friends acknowledged that Meulstee had been battling drug problems.
A candlelight vigil was scheduled for Thursday night on Mendoza Road.

The article didn't indicate how he got hold of the loaded gun.

Every gun in the hands of a child must first pass through the hands of an adult.
