CASA GRANDE — A man who intervened as a couple were arguing in a hotel parking lot early Saturday was shot fatally and the man in the argument has been arrested.

Casa Grande Police were called to the Radisson Hotel, 777 N. Pinal Ave., at 2:30 a.m. on Saturday regarding a shooting in the parking lot.

Upon their arrival, officers discovered 35-year-old Casa Grande resident Brian Robinette with what appeared to be multiple gunshot wounds to the upper torso. Officers immediately initiated lifesaving measures, according to police spokesman Thomas Anderson. The victim was transported to Banner Casa Grande Medical Center, where he died of his injuries.

According to Anderson, detectives have determined the victim intervened in a physical argument between a male and female couple in the parking lot of the hotel. The victim and male suspect engaged in a verbal altercation. The male suspect then shot the victim multiple times. The male suspect and the female he was arguing with both fled the scene. No one else was injured.

The suspect was identified as 21-year-old Giovanni Olivieri and the woman he was arguing with is his 19-year-old girlfriend. At approximately 3:30 p.m. Saturday, Casa Grande Police Department detectives located and arrested Olivieri on the street in front of his girlfriend’s residence in the Rancho Grande neighborhood. Olivieri was booked in the Pinal County Adult Detention Center.

Anderson said CGPD is working closely with the Pinal County Attorney’s Office to determine all charges that will be submitted.

The Pinal County Sheriff’s Office, Attorney’s Office and the U.S. Marshals Service assisted in the apprehension, Anderson said.

Anyone with further information regarding the incident is asked to call the Police Department at 520-421-8700.
