CASPER — A 41-year-old Casper man faces a potential life sentence on charges related to the Dec. 18 stabbing of his ex-girlfriend in an apartment complex hallway. The probation officer told Wood to go back to the apartment, turn himself in and not destroy any evidence. Wood told her he had “hot railed” meth while he was at his home. The girlfriend’s roommate told police he did not see what happened after Wood and her roommate went into the hallway. The affidavit states the roommate saw Wood dragging her roommate down the hallway by her hair and rushed over as Wood let her go.
