A state appeals court has denied a new trial for a former Lancaster County man convicted of first-degree murder in a 2016 shooting.

Lucas Newnam, 33, is serving life in prison for killing Julius Dale at a home in Sadsbury Township.

Newnam argued his conversations with his mother during prison visits should not have been allowed at trial. Superior Court denied that claim because signs in the room indicate that conversations are recorded.

Newnam also claimed the jury should have been given a Castle Doctrine instruction before deliberations. The court found no evidence of unlawful entry at the home Newman used for drug dealing, and that illegal activity removes Castle Doctrine as a potential defense.

Newnam and Dale formerly lived together at the home. Prosecutors said the two were arguing when Newnam shot Dale in the chest.
