(JTA) — The convicted murderer of an 11-year-old Jewish girl in 1969 will not receive a new trial, a Baltimore judge ruled.

Circuit Judge Edward Hargadon in his ruling last week on the appeal by Wayne Stephen Young said jurors who found Young guilty of killing Esther Lebowitz in 1972 were adequately advised of how to try the case, the Baltimore Sun reported.

Attorneys for Young, 68, had requested the new trial based on a 2012 ruling by the Court of Appeals of Maryland, the state’s highest court, which found that many convictions before 1980 are invalid because jurors were given unconstitutional instructions. Young’s attorney said she would appeal the ruling.

Young was sentenced to life in prison for the murder and has been denied parole 12 times. He claimed during his trial that he was temporarily insane.

Esther was missing for two days before her body was found about a half-mile from her Baltimore home. She died from 17 blows to the head.

Her family has since moved to Israel and did not attend a hearing on the case last month. About 200 Baltimore Jews protested the hearing.
