Officer Who Flirted Fails to Regain Job : Police: She argues unsuccessfully that the attention she gave a high school student was merely to protect her undercover status on campus.

A former Los Angeles policewoman who allegedly became romantically involved with a high school football player while serving as an undercover narcotics officer has lost yet another bid to get her job back.

A Police Department Board of Rights late Tuesday ruled that Sharon Fischer should not be reinstated after her dismissal for writing sexually suggestive letters to the 17-year-old Granada Hills student, telephoning him at home and maintaining an improper relationship with a minor.

The board found her innocent of a charge that she allowed the teen-ager to fondle her.

Fischer, 26, has denied any romantic involvement with the student and has maintained that she was only trying to keep her identity as an undercover narcotics officer a secret after some Kennedy High School students caught on to her.

Police spokesman Cmdr. William Booth said it is up to Chief Daryl F. Gates to either uphold the board’s recommendation to officially fire Fischer or overrule the decision. Gates has rarely reduced a board’s recommended punishment, he said.

Detective Gregory Dust, a defense representative who represented Fischer before the three-officer board, said she has been advised by her lawyer not to talk publicly about the case until Gates makes his ruling.

However, Dust said he would file a written appeal soon asking Gates to suspend Fisher for six months and then allow her to return to work.

Fischer was dismissed by Gates in 1987 after the charges were aired in proceedings before a department hearing officer. Since then, she has been battling to get her job back. Last summer the California Supreme Court upheld a lower court ruling that she was entitled to a full-scale hearing before a Board of Rights.

The department had maintained that she was a rookie on probation when the alleged relationship with the student developed and, therefore, was not entitled to such a hearing.

In a Board of Rights hearing--unlike a proceeding before a hearing officer--the city bears the burden of proving its charges and the accused officer can cross-examine department witnesses.

In 1986, Fisher was assigned as an undercover officer at Kennedy High as part of the department’s School Buy operation. After receiving complaints from the mother of the football player, Akili Calhoun, police officials first suspended and later fired Fischer.

During the hearing before the board, Sgt. Michael Downing, who presented the department’s case, read from letters that Fischer had sent to Calhoun. The letters suggested that the two might have sex on the campus football field or in a car.

Dust said that Fischer admitted sending the letters and that she associated with Calhoun on campus and hugged and kissed him. She said she once called the youth at home and asked if he knew anyone who was selling narcotics, Dust said.

However, Dust maintained, Fischer acted only to protect herself. At various times while she was working undercover, she was verbally threatened by students who had caught on to the fact that she was a narcotics officer, he said. She also was physically attacked by a student, he said.
