OAKLAND — A suspect in a Friday shooting that resulted in a futile 12-hour police operation at an East Oakland apartment will not be charged because the victim is not cooperating, investigators said Tuesday.

The suspect, Antoine Harris, 21, who surrendered to police Saturday, was released from custody Tuesday afternoon.

Authorities had searched for him near the same East Oakland apartment in the 2700 block of 74th Avenue where two Oakland SWAT officers, as well as a gunman who had killed two other officers, died in a shootout March 21.

The Alameda County sheriff's SWAT team entered the unit where they thought Harris might be early Saturday morning but could not find him. He surrendered to police Saturday afternoon.

Police said the Alameda County District Attorney's Office declined to file charges against Harris because they lack the cooperation of the 20-year-old shooting victim.

Sgt. Rebecca Campbell said Tuesday that the victim refused to meet with investigators, look at a photo lineup or give a signed statement or a medical release to show he had suffered injuries.

The victim, whose name was not released by police, left Highland Hospital on Saturday afternoon against the advice of doctors. A bullet was still lodged in his stomach, police said.

The shooting happened about 1:20 p.m. Friday near 76th Avenue and MacArthur Boulevard. A witness told police Harris had fled to the apartment, where he supposedly lived with a girlfriend.

Police believed he was in the apartment building because witnesses saw him enter. A police officer at the scene also saw him some time after the shooting in one of the units, but Harris somehow eluded capture.

According to Campbell and Officer Robert Trevino, Harris gave conflicting statements to police about his activities on the day of the shooting. In one version, he claimed he was at a liquor store, and in another, he said he was having minutes added to a cell phone at another store.

Police are investigating the case and said they believe the shooting was over a woman or some kind of debt.
