How a suspected police chief murderer avoided capture for 37 years

(Boston 25 News) - For decades, he was one of the FBI's most wanted fugitives.

According to these documents it was his wife Lillian Webb, loyal to the end, who kept him hidden inside 28 Maplecrest Dr. in Dartmouth. When the time came, she buried him.

WHO WAS DONALD WEBB

Webb, according to police, was a mobster, tied to the Patriaca New England crime family, based in Providence. Webb specialized in jewelry store burglaries.

He was a flashy dresser, a big tipper and known to love dogs, according to the FBI. He went by many different aliases over the years.

In December 1980, while casing his next target, Webb shot and killed

Webb, already a fugitive from New York State, swore he was never going back to prison.

According to a state police affidavit, Webb suffered a severe leg injury in the struggle with the police chief. After fleeing the murder scene, Webb drove back to Massachusetts. Using the alias "John," Webb spent a full month at Toby Hospital in Wareham, according to an interview with Lillian and her lawyer.

After his release, police records show that Webb moved in with wife Lillian into their home in New Bedford, which police believe had a hidden room. For 17 years, Webb lived in the darkness of his basement, in a hidden room.
