Robert Burton of Abbott, who led police on the state’s longest ever manhunt this summer, has been indicted by a Piscatiquis County grand jury on a count of murder in connection with the death of Stephanie Gebo. The indictment on the murder charge and a second on a charge of possession of a firearm by a prohibited person – Burton is a convicted felon and is barred from having a gun – were handed up Thursday. Gebo, 37, a single mother of two, was shot to death at her home in Parkman on June 5.
