Court papers: Daniel Lee Cook confronted maintenance worker about music before stabbing

PHOENIX - A confrontation that led to a maintenance worker's death in north Phoenix started when the suspect wanted the victim to turn down his music, according to court papers.

The suspect, 39-year-old Daniel Lee Cook, turned himself in to Phoenix police around 1 p.m. Monday.

Around 11:45 a.m. Sunday, officers responded to an apartment complex near Dunlap and 19th avenues and the victim, 22-year-old Richard Bankston, was transported to a hospital with a stab wound.

Bankston was pronounced dead about a half hour later, according to court papers.

Court papers said Cook walked down to the complex swimming pool where Bankston was cleaning.

Cook admitted to police that he yelled at Bankston to turn down the music in the pool area, papers said.

He then reportedly pushed Bankston into the pool and began fighting him.

According to papers, Cook said he didn't recall stabbing Bankston but admitted to carrying a pocket knife and pepper spray to the pool area at the time.

Cook told police he then went to his apartment, got his cell phone and called his father while leaving the scene.

He told his father he killed someone and needed to leave the area, according to papers. He fled for the night and reportedly got rid of his clothes and knife.

Cook then contacted his sister to surrender to police.

Police recovered surveillance video from the complex showing Cook and Bankston getting into an argument.

Bankston was seen being pushed into the pool, and footage reportedly showed Cook making stabbing motions with his right hand, papers said.

A resident also captured cell phone footage of Cook leaving the pool area with his right arm covered in blood, according to paperwork.
