Antioch police announced Monday that five subjects believed to be gang members or connected to gangs have been arrested for involvement in a fatal shooting on March 31.

According to an Antioch Police Department press release, Antioch residents Giovanni Lopez, 26; Juan Peter Herrera, 22; Pittsburg resident Raymond Wehr, 22; plus a 17-year-old boy from Antioch and a 17-year-old boy from Pittsburg were taken into custody.

The release states that the five were involved in a shooting at Cruiser’s Saloon that resulted in the death of Antioch resident Lizandro Tony Bertolazzi, an innocent bystander.

The case has yet to be presented to the Contra Costa County District Attorney’s Office, and those arrested are being held on probation or parole holds.

According to the police report, a group of men expelled from Cruiser’s Saloon on A Street returned after midnight wielding baseball bats with the intent to start a fight. One of the men pulled out a handgun and fired at least one shot inside the bar, hitting Bertolazzi.

In order to protect the integrity of the investigation, the department is not identifying who is suspected of firing the shot that killed Bertolazzi.
