SAN FRANCISCO – A second man convicted in the murder and street robbery of a Maine tourist more than five years ago faces 25 years to life in prison.

Jurors deliberated for four hours Thursday before returning their verdict against Tremayne Collier, 33, of Richmond, whose case was continued for sentencing.

Prosecutors said Collier took Shayne Worcester’s wallet during the May 26, 1999, mugging just before Daniel Mooring shot and killed him. A filmmaker, Worcester grew up in Southwest Harbor, Maine, but was living in Portland at the time of his death.

Collier’s conviction was secured, in part, because of a letter he wrote that suggested that he was involved, the San Francisco Chronicle reported.

Mooring, 24, was convicted in January of murder during the commission of a robbery and sentenced to life in prison without the possibility of parole.

Authorities had said Mooring was the one who pulled the trigger on the 29-year-old Worcester, but the jury in Mooring’s trial found that prosecutors hadn’t proved it.

Worcester was shot even though he had already turned over his wallet to Collier and was lying helplessly face down on the sidewalk, prosecutors said.
