Robin Shea was 21 when she was shot to death on the evening of October 10, 1981, while riding in a jeep in Norton, Massachusetts. She had been dating 38-year-old Andrew Peter Dabbs for about six months and they had recently moved into an apartment in Derry, New Hampshire.

Dabbs fled immediately after the shooting. He was indicted for murder on November 3, 1981, and a state arrest warrant was issued; a federal warrant for unlawful flight to avoid prosecution followed on September 20, 1982. Investigators tracked him to Mount Vernon, New York, early on but he escaped as police closed in. He has remained a fugitive and is considered armed and dangerous; the FBI is offering up to $20,000 for information and has released an age-progressed photo.

If anyone knew Robin, her movements in 1981, or has information about Andrew Peter Dabbs’s whereabouts then or since, please come forward.
