An Elmira man has pleaded guilty to all charges related to a home invasion robbery and assault that took place in Lansing last October. Bradley Brown admitted Tuesday in Tompkins County Court to breaking into a couple’s home on Triphammer Road and threatening the occupants with a wrench. He stole property and committed sexual assault before abducting the victims. A massive manhunt throughout Tompkins and Chemung County lead police to Brown after the break-in. Brown is scheduled to be sentenced in September.
