SAN DIEGO -- The Roman Catholic Diocese of San Diego turned over information regarding 15 child sexual abuse cases involving priests to District Attorney Paul Pfingst, it was reported Wednesday.

Pfingst, who requested the information, said he had talked with Bishop Robert Brom, who "promised 100 percent cooperation with our investigation into criminal acts," The San Diego Union-Tribune reported.

Four cases in which the victims were underage when they reported the abuse had already been reported to law enforcement, Pfingst said.

The other 11 cases involve adults who recounted to diocese officials that they had been abused as children, some saying the abuse occurred decades ago, the newspaper reported.

The most recent complaint received by the district attorney was from 1996.

The request by Pfingst for the information came after Brom held a news conference earlier this week.

On Monday, Brom told reporters that the Roman Catholic diocese of San Diego has received complaints against 23 priests for sexually abusing minors since he became bishop 12 years ago.

All but four of the priests involved in the allegations either left the priesthood or were dead before the allegations surfaced, Brom said.

Of the four who were still active in ministries, "the conclusion was reached that three of them should no longer be in the ministry and they are not," Brom said, adding that "one remaining case is under investigation."

Brom did not identify the priests or discuss details of the one case that is still pending.

Monsignor Steven Callahan, the diocese's chancellor, said church officials turned over information on the 15 cases to Pfingst after he asked for clarification of Brom's announcement, according to The Union-Tribune. The other eight cases apparently involve priests in Imperial County, which is included in the local diocese.

It was not immediately clear if information on those eight cases was forwarded to the Imperial County District Attorney's Office, the newspaper reported.
