Prosecutor’s Use of Country Club Facilities Investigated : Inquiry: Focus is on assistant district attorney’s possible improprieties regarding prestigious Marbella establishment.

Sheriff’s deputies are investigating possible misuse of facilities at the prestigious Marbella Golf and Country Club by a high-ranking prosecutor in the district attorney’s office, authorities confirmed Friday.

Investigators have interviewed Assistant Dist. Atty. Jan J. Nolan, a member of the club here, to determine whether she is connected to alleged misuse of facilities “under false pretenses,” Sheriff’s Lt. Bob Rivas said.

Nolan could not be reached for comment.

Rivas declined to provide any specifics of the investigation, which was prompted by an anonymous call to a sheriff’s tip line in February. Rivas declined to say whether Nolan was mentioned in the call.

Investigators are “talking to a lot of people right now,” Rivas said. “We don’t know if there is a violation here.”

The investigation has not affected Nolan’s job in the district attorney’s office, said Maurice L. Evans, chief assistant district attorney.

As director of Superior Court services, Nolan oversees the several units of the district attorney’s office, including narcotics, career criminals, major frauds and environmental and consumer protection. Evans said Nolan has been with the district attorney’s office for more than a decade.

“She’s still coming to work and doing her typically good job,” said Evans, who added that the district attorney’s office knew about the investigation but not its specifics. “We’re very optimistic that there is an adequate explanation” to what prompted the investigation, Evans said. He also said his office would conduct an internal investigation.

Rivas said sheriff’s personnel indicated that they may finish their investigation by the end of next week. After completing their inquiry, sheriff’s deputies plan to forward their findings to the state attorney general’s office in San Diego to determine if a charge will be filed, Rivas said. He said investigators contacted the state attorney’s office in order to avoid any conflict of interest by the district attorney’s office.

Calls to the Marbella Country Club general manager and president were not returned Friday. The investigation comes at a time of financial difficulties at Marbella, one of the county’s most prestigious golf course resorts. The club, which opened in 1988 and has more than 800 members, has not yet emerged from a September, 1992 bankruptcy filing.
