PHOENIX — Three men have been arrested for murder after a group of people rushed into a Phoenix apartment and killed a man during an altercation.

Police say the incident occurred at an apartment near 23rd Avenue and Deer Valley Road before 1 a.m. on Saturday.

Multiple masked men reportedly forced their way into an apartment after an earlier verbal altercation between neighbors.

One of the men pulled out a gun and shot the victim, 25-year-old Richard Coss, in the chest. He died at the scene.

A witness said all but one of the suspects were masked and were not identifiable. Police and a witness were able to identify 46-year-old Carl Robert Blazak as one of the suspects.

Blazak’s wife reportedly said she was not aware of the homicide, but did tell Blazak that she had a dispute with the upstairs neighbors.

Blazak told police he was present during the attack but did not shoot the victim.

Investigators later identified two others who were believed to be involved in the crime. Keith McCollough, 49, and Jimmy Eslinger, 29, were arrested on Monday and Tuesday on first-degree murder charges.
