A 17-year-old boy was stabbed to death in Peoria, Arizona, on Thursday by a man who told police he did it because the boy’s rap music made him feel “unsafe.”

In a convenience store just before 2 a.m. on July 4, Michael Paul Adams, 27, lunged at the teen and allegedly stabbed him in the back and slit his throat, according to a probable cause statement obtained by BuzzFeed News.
