Killings by officers not on homicide list

Not included in a Tucson Citizen list of seven Tucson criminal homicides since Feb. 24 are two fatal shootings involving law enforcement officers.

One occurred in the city Feb. 28 and the other on Feb. 29 in the unincorporated county.

Such line-of-duty shootings, under FBI guidelines, are listed separately from criminal homicides unless investigations show they were criminal acts.

Both officer-involved shootings are under investigation by homicide and internal affairs detectives at the officers’ agencies. Such investigations are standard procedure for such shootings at both agencies.

The officer-involved shooting in the city occurred when Officer Claude Ralls shot a man as he drove from a home.

Ralls had been on patrol on the West Side when he spotted a white Chevrolet Malibu believed connected to an armed robbery in Sahuarita, said Sgt. Fabian Pacheco, a police spokesman.

The car was parked in a carport in the 700 block of North San Rafael Avenue, a house that was under investigation because of reports of drug activity there, police said.

Ralls radioed for backup but before more officers arrived, Louis Richard Arboisiere, 32, of Nogales came out of the house and got into the Malibu, police said.

Arboisiere tried to drive off while Ralls, pistol drawn, ordered him to stop and get out of the car, Pacheco said. When Arboisiere didn’t stop, Ralls shot him. Arboisiere died that afternoon at a hospital, Pacheco said.

Online court records show Arboisiere was found guilty of attempted theft in Santa Cruz County in 2003.

Police detained eight people at the North San Rafael house, arresting five of them in unrelated cases, Pacheco said.

The man killed by deputies Friday afternoon was 25-year-old Vincent Samuel Azzarello, sought in a reported domestic violence incident.

Deputies Matthew D. Salmon and Bruce E. Haufe tracked Azzarello to a mobile home in the 5500 block of North Anway Road, sheriff’s spokeswoman Deputy Dawn Hanke said.

Azzarello ran from the deputies and fired at least two shots, hitting Salmon in the chest and Haufe in the hand, Hanke said.

Salmon, saved by his bullet-resistant vest, returned fire killing Azzarello, deputies said.

The two deputies were treated at University Medical Center and are recovering at home, Hanke said.

Two men at the house were arrested in cases not related to the domestic violence call.

The results of criminal investigations in the shootings will be reviewed by the Pima County Attorney’s Office to determine if they were criminal or justifiable. Boards of inquiry at both agencies will be held.

Citizen Online Archive, 2006-2009

This archive contains all the stories that appeared on the Tucson Citizen's website from mid-2006 to June 1, 2009.

In 2010, a power surge fried a server that contained all of videos linked to dozens of stories in this archive. Also, a server that contained all of the databases for dozens of stories was accidentally erased, so all of those links are broken as well. However, all of the text and photos that accompanied some stories have been preserved.
