LOS ANGELES (AP) _ Authorities are searching for a 14-year-old girl they say was sexually involved with a man with AIDS who died in the jail ward of the Los Angeles County-USC Medical Center, a sheriff's deputy said.

Wert Granville Yarbrough, 33, died Tuesay in the ward, where he was being treated for acquired immune deficiency syndrome, Deputy Sheriff Mason Kenny said Tuesday.

An autopsy to determine the cause of death was planned.

Yarbrough was to have been released Wednesday after serving a 180-day sentence for statutory rape involving a second teen-age girl, Kenny said.

The man pleaded no contest to unlawful sexual intercourse with a 14-year- old El Segundo girl in October, according to court records in Torrance. That girl is undergoing tests for AIDS at UCLA Medical Center, Kenny said.

Yarbrough also was sexually involved with another 14-year-old girl, according to El Segundo police reports, but he was not charged in that case.

Officials are looking for that girl, who moved out of state, said Kenny.

AIDS is an affliction in which the body's immune system becomes unable to resist disease. It can apparently be spread by sexual contact, contaminated needles and blood transfusions, but not by casual contact.

El Segundo and Torrance are Los Angeles suburbs.
