According to reports, Lagana had been parked in a vacant lot near Heimer's home, and honked his horn until Heimer came outside. 

As Heimer was walking towards the lot, Lagana sped out of the lot and into the roadway where he swerved onto the sidewalk to strike Heimer with his vehicle before driving away.

Lagana continued down the sidewalk before turning his vehicle around to run over Heimer who was still lying injured on the ground. Police said Lagana then left his vehicle to begin stomping on Heimer's head.

Officials said that one witness stopped Lagana by firing a warning shot with his own gun and preventing Lagana from leaving the scene. Because of that, police said they were able to arrest Lagana as soon as they arrived on scene.

Mesa Fire & Medical attempted life-saving care, but Heimer was pronounced dead on the scene.

Lagana later told authorities that he knew the victim, and had previously been allowed to park and stay on the victim's property as he was living out of his vehicle.

According to reports, Lagana did not provide a reason for the assault.

Lagana is being held in a local jail on 1st-degree murder charges.
