PHOENIX (AP) — Bond has been set at $1 million for an alleged gang member who police say killed a man with an ax in Phoenix, nearly decapitating him.

Phoenix police say 31-year-old Christopher Paul Mason was arrested Thursday on suspicion of premeditated first-degree murder.

He doesn't have an attorney as of Friday.

Police say Mason told some witnesses that he killed 35-year-old Joshua Calkins earlier this year because Calkins had robbed Mason's ex-girlfriend at gunpoint.

Calkins' body was found April 16 in an alley wrapped in plastic with multiple injuries to the neck, back and body.

Police say Calkins' hands were tied behind his back, and bloody towels were nearby.

Court documents show at least one person was inside the apartment when Mason allegedly attacked Calkins with the blunt side of an ax.
