ALLENTOWN, Pa. (AP) - Authorities say a Florida woman suspected in a 25-year-old slaying in Pennsylvania was involved in an earlier homicide.

Police arrested 55-year-old Lucinda Andrews earlier this month at her home in Jacksonville, Fla. and charged her in the fatal shooting of 51-year-old Allentown resident John Mayerchak in 1985.

A grand jury charged Andrews earlier this year after authorities say DNA evidence and a friend's statement linked her to the killing.

The Morning Call of Allentown reported Monday that Andrews killed a bartender in 1971. According to the paper, Andrews was sentenced to up to six years in prison for voluntary manslaughter after she was found delinquent in juvenile court.

Andrews is in custody in Florida awaiting extradition to Pennsylvania.
