On the night of September 4, 2021, 35-year-old Brian Robinette was shot in the parking lot of a Radisson Hotel in Casa Grande, Arizona, after stepping in to try to break up a heated, physical argument between a young couple.

Emergency responders arrived at about 2:35 a.m. and transported Robinette to Banner Casa Grande Medical Center, where he later died of his injuries. Detectives located and arrested Olivieri that same afternoon in the Rancho Grande neighborhood in front of his girlfriend’s residence; he was booked into the Pinal County Adult Detention Center. Reports state Olivieri was later tried, found guilty of second-degree murder and other charges, and sentenced to 28 years in prison.

What information can anyone share about Brian Robinette’s life or about witnesses who were at the hotel that night?
