David Helmer, a 44-year-old Caucasian man, died after an altercation at an apartment complex on Greene Lane near Hacienda Avenue and Maryland Parkway in Las Vegas on August 20, 2016. Officers responding to a battery report found Helmer injured and he was taken to Desert Springs Hospital Medical Center, where he was later pronounced dead.

Detectives initially opened the case as a homicide because the injuries followed a physical fight, but investigators at the scene felt the trauma did not appear sufficient to cause death. The Clark County Coroner’s Office later ruled the cause of death dilated cardiomyopathy, with methamphetamine intoxication and the psychological stress of the altercation listed as significant contributing factors. The manner of death was classified as accident and no arrest was made in connection with the fight.

Did anyone in the Greene Lane area see or hear anything the evening of August 20, 2016, that could shed light on what happened before Helmer became ill?
