FATAL SAN DIEGO POLICE SHOOTINGS, 1990

* Feb. 9: Officer John Cain shoots suspected purse snatcher Jorge Robles, 29, after Robles points a .22-caliber handgun at the officer. The district attorney’s office later clears Cain.

* April 8: Officer Derek Diaz fatally shoots Gregory J. Markley, 27, a transient who police say began to pull a knife when officers tried to detain him. Police say Markley had just broken into a car parked in the driveway of a nearby house.

* May 21: Officer Thomas O’Connell shoots a mentally disturbed man, Jose Eleazar Lopez-Ballardo, while the man waves a cement trowel on Interstate 5. O’Connell says he feared Lopez would harm him or other motorists. Dist. Atty. Edwin Miller rules the shooting justifiable, saying the trowel could have had a “potentially deadly employment.”

* June 16: Officer Bradley Phelps shoots Luis Francisco Perez, 28, after he threatens Phelps with an aluminum baseball bat. Miller rules the shooting justifiable. Although police mistakenly assumed Perez was on drugs and 4 1/2 inches taller than he actually was, Miller says Perez was a “large, enraged, and irrational man.”

* June 20: In a similar case, Officer Danny Angotti shoots a bat-wielding man, Walter Andrew Welch, 41, a former attorney who was smashing car windows in Mission Beach. Police say Angotti fired when Welch was 10 feet away, with the bat raised in one hand and scissors pointed in the other. Miller rules the shooting justified.

* July 21: Officers Loretta Glick and Robert Walter shoot Bruce Todd Riddle, 29, after responding to a call that Riddle was under the influence of drugs and threatening to kill himself. At first, officers say, they talked to Riddle, who they say had a knife tied to his wrist and was acting irrationally. After an hour, though, police say, Riddle charged the officers with the knife.

* Aug. 6: Detective Leslie Oberlies shoots John Joseph Kelley, 30, three times in the parking lot of a Mission Valley Denny’s restaurant. Police say Oberlies fired the shots at Kelley, who was sitting in the driver’s seat of a borrowed Cadillac, after Kelley made a “furtive movement” between his legs, interpreted by Oberlies as reaching for a weapon. No weapon is found. Oberlies had gone to the restaurant after police had been alerted that Kelley had arranged a meeting with his estranged wife there. Police suspected Kelley of stealing his own children away from her.

Sept. 11: Officer Charles M. Rice Jr.--son of Deputy Chief Mike Rice, who is leading a review of the department’s shooting policies--shoots William Slusar, 39, twice through the chest. Police had been called to Slusar’s residence after the victim’s parents had called paramedics and the Fire Department. Slusar, who police were told had overdosed on drugs and was contemplating suicide, had struck his father, prompting the call. Police were told by paramedics and the Fire Department that Slusar was dangerous.

* Sept. 13: Officer John Cain, who killed Jorge Robles in February, shoots Anthony Tumminia, 21, after, police say, Tumminia attacked Cain and another officer with nunchakus in Ocean Beach.
