Police found an assault rifle, a semi-automatic pistol and a handgun when they arrested a 44-year-old Oahu Community Correctional Center officer for allegedly shooting his 66-year-old mother last week, according to court documents.

A preliminary hearing for Anthony F. Pereira II will be held in Honolulu District Court today. He is charged with second-degree murder, use of a firearm in the commission of a felony, third-degree promotion of a dangerous drug (methamphetamine), kidnapping and first-degree terroristic threatening. He is being held at Halawa Correctional Facility unable to post bail of $1 million.

The kidnapping and terroristic threatening charges stem from a report by a 48-year-old woman who drove to the Waianae police station at about 3:30 p.m. Friday telling officers that “he (Pereira) shot her (mother Barbara Pereira) and he’s coming after me,” according to a police affidavit filed in District Court on Monday.

The female victim said, “I was held at the house by Maili Beach, and he shot her.” She identified the shooter as “Tony,” the affidavit said.

Barbara Pereira was shot in the head, the affidavit said.

Police were sent to the Maili home on Farrington Highway on Friday afternoon after gunshots were reported.

Pereira was found sitting in the garage next to a gun safe and “appeared to be crying and distraught and asking for his daughter,” the police affidavit said. The suspect also said he was sorry.

The responding officer told the suspect to lower the AR-15 assault rifle he was carrying and that he would help him talk to his daughter and wife, according to the affidavit. As additional officers arrived at the Maili home, the suspect suddenly appeared to be gasping for air and “started spitting up and foaming at the mouth, then he began to lie back in the corner and appeared to have convulsions,” the affidavit said.

Arresting officers took the rifle from the suspect and moved him to where he could get medical attention.

Besides the AR-15 assault rifle, police found a Glock model 17 automatic pistol and a Smith &Wesson Model 66 .357-caliber pistol on the table next to the victim.

The Department of Public Safety said Pereira was hired in August 2002. However, Pereira has not reported to work since April 10 and was placed on unpaid leave for not showing up, the department said Monday.

The department is conducting an internal administrative investigation and assisting Honolulu police in their criminal investigation, Public Safety Director Nolan Espinda said.
