Lisa Michelle Lambert appeals murder conviction

PHILADELPHIA (AP) – A Pennsylvania woman serving a life-without-parole sentence for the 1991 murder of a teenage rival is asking a federal court to review what she calls her “wrongful conviction.”

Lisa Michelle Lambert was sentenced 22 years ago to life without parole for slashing the throat of 16-year-old Laurie Show at the victim’s East Lampeter Township home.

Lambert says in her appeal that Lancaster County’s court system is corrupt and alleges the now-dead district attorney who prosecuted her believed she was innocent. Two other courts previously have rejected Lambert’s appeals making the same claims.

District Attorney Craig Stedman on Friday called the latest appeal “another desperate attempt to avoid being held accountable.”

Lambert, now 40, is imprisoned in Massachusetts.

She was 19 at the time of Show’s murder.
