PHILADELPHIA — A man has been ordered to stand trial on charges of lifting the wristwatch off a man dying in a Philadelphia hospital waiting room.

Prosecutors say 45-year-old Richard Alten stole a watch from 63-year-old Joaquin Rivera as the older man sat unresponsive in an emergency room waiting area in November. Officials say Rivera died of a heart attack.

Two other suspects have already pleaded guilty and been sentenced to probation.

Luis Carrasquillo, a friend of Rivera's, said he saw the robbers take the watch even though they knew he was watching.

Alten's attorney argued that the case should be thrown out, especially the robbery charge, because a dead person cannot be robbed. But authorities said they do not know whether the victim was dead at the time of the crime.
