Authorities are searching for a third suspect in connection to the slaying of 27-year-old Odin L. Lloyd, calling Ernest Wallace, 41, “armed and dangerous.” In a statement, the Bristol District Attorney’s Office said that Wallace is wanted on a charge of accessory after the murder of Lloyd, a 27-year-old Dorchester man who was allegedly shot to death by former Patriots player Aaron Hernandez on June 17. Wallace has a “very heavy build” and was last seen driving a silver or gray Chrysler 300 with a Rhode Island license plate of 451-375, police said. Anyone who spots Wallace is asked to call North Attleborough police at 508-695-1212. The statement did not list a hometown for Wallace, and North Attleborough police and the Bristol District Attorney’s Office had no comment beyond the advisory. David Procopio, a State Police spokesman, said that Wallace is most recently from Connecticut, and the section of the advisory that mentions “active felony warrants in Massachusetts” refers to the Lloyd case only. Wallace also goes by the names “BO” and “Fish” and has ties to Connecticut, Georgia, Florida, and Massachusetts, according to the statement. The advisory did not detail Wallace’s alleged role after Lloyd’s death. At his arraignment Wednesday in Attleboro District Court, Hernandez pleaded not guilty to murder and five firearms-related charges.
