Roberto Simmon, 34, was shot and killed late on the night of June 12, 2008, at an apartment complex in eastern Las Vegas. Police were called to 1060 Sierra Vista Avenue at about 10:52 p.m., and the coroner later determined Simmon died from a gunshot wound to the neck.

Contemporaneous reports identified the shooter as an on-site security guard working at the complex. The guard told detectives Simmon reached for the guard’s firearm during the confrontation, while Metro police emphasized the investigation was ongoing and did not name the guard or the employing company.

Does anyone have information about what happened that night or knew Roberto?
