On February 9, 2016, Michael Allen Guinn, 42, was found with a gunshot wound to the chest in the 2900 block of Kennewick Drive in southeast Las Vegas. Officers who responded around 1:30 p.m. located him lying in front of a house; he was transported to Sunrise Hospital and Medical Center and died of his injuries.

Police say an argument occurred in front of the house between Guinn and a man and a woman. The pair got into a vehicle and one of them fired a single shot into Guinn’s upper torso before fleeing. The coroner’s office ruled Guinn’s death a homicide.

Las Vegas police later arrested 17-year-old Devin Aluague at a home in the 1300 block of Cashman Drive; he was booked on one count of open murder with a deadly weapon and was certified as an adult. The second person who had been in the vehicle was interviewed and is no longer being sought.

If anyone has information about what led to the confrontation or witnessed the events on Kennewick Drive that day, please share what is known.
