Pair arrested in Newport Beach homicide and suspected robbery

Two suspects were arrested on Tuesday on suspicion of robbery, with one of those suspects believed to be responsible for the murder of a Newport Beach man, police said.

Newport Beach police said they responded to a call reporting a man who was down and bleeding at 1:36 a.m. Saturday, Sept. 30, near 34th Street and Seashore Drive. Upon arrival, officers located the victim, who appeared to have a stab wound, and transported him to a local hospital, where he later died of his injuries. That victim has been identified as Robert Tamaccio, 46, of Newport Beach.

Officers, detectives and crime scene investigators subsequently launched a homicide investigation in collaboration with other local agencies.

The Newport Beach Police Department announced that Randolph Loren Aguirre, 55, and Desirre Ritalucy Aguirre, 30, both of Brea, were arrested at approximately 5 p.m. Tuesday in Brea. Jail records indicate Randolph Aguirre is being held without bail while Desirre Aguirre is being held on $150,000.

Both were arrested on suspicion of robbery, but Randolph Aguirre was additionally charged on suspicion of homicide and a parole violation. They made their first appearances in court Thursday and are next scheduled for arraignment and bail review hearings at the Central Justice Center in Santa Ana on Oct. 20.

Charges filed against Randolph Aguirre now include three additional sentencing enhancements: one for the special circumstance of robbery and two for personally using a deadly weapon. Both robbery charges have been defined in the second degree. Neither of the Aguirres entered pleas Thursday.

Court records indicate that in October 2021 Randolph Aguirre pleaded guilty to charges of assault with intent to commit sexual offense, assault with deadly weapon other than firearm, resisting an executive officer, possession of firearm by a felon, illegal use of tear gas, and being prohibited person owning ammunition.

Desirre Aguirre was out on $10,000 bail for a separate robbery in the second degree on Aug. 19. She pleaded not guilty to that charge.
