Police on Monday identified the man they believe shot and killed another man in Phoenix.
The shooting was reported around 10 p.m. Sunday at an apartment complex near 23rd Avenue and Butler Drive, according to the Phoenix Police Department.
Police said the victim, a man in his 30s, was pronounced dead at the scene. Investigators said it looked like he had been shot three times.
Police said the suspect, later identified as Matthew Brown, 41, and the victim knew each other.

"The victim arrived at the apartment to confront Brown and another person about their relationship," according to Sgt. Vince Lewis of the Phoenix Police Department. "Brown exited the apartment to confront the victim. During that time, the suspect shot the victim."
Court documents provide more details about the moments leading up to the shooting.
According to the arresting officer's probable cause statement, the victim had threatened Brown and his girlfriend earlier and then returned to "the residence and began to hit the windows to the apartment with closed fists."
Brown told police he then got into a verbal argument with the victim, who was still outside the apartment. Brown said he had his gun in his hand at the time and was yelling to others who were there to call 911.
According to the arresting officer, Brown said he opened the door to confront the victim and warn him "that he would not be entering inside the apartment."
Brown said the victim "approached the opened front door" despite "a verbal warning, then a three second count down (sic) to stop walking towards the front door."
According to police, Brown admitted firing at the victim twice from 6 to 10 feet away -- once deliberately and again as he flinched.
"A third spent shell casing was located on scene that Matthew could not explain," the arresting officer wrote, clarifying that the victim never set foot inside the apartment.
Police said when they arrived, Brown came out of the apartment and said he was the shooter.
He is now facing a charge of second-degree murder.
Brown made his initial court appearance Monday; a judge set a secured appearance bond of $15,000 and scheduled a preliminary hearing for Sept. 20.
