Donald Webb was wanted for the December 1980 murder of then Saxonburg, Pennsylvania police chief Gregory Adams.
Webb was one of the longest tenured fugitives ever to appear on the FBI's "Ten Most Wanted Fugitives" list, according to the department.
The remains of a longtime fugitive accused of killing a Pennsylvania police chief have been found in his wife's backyard.
She ignored reporters' questions when she returned to her MA home Friday night.
Webb passed away about 17 years ago, in 1999, investigators learned.
Saxonburg police Chief Joe Beachem and Mayor Bill Gillespie were driving back to Saxonburg from Lillian Webb's home in MA as the news of the remains being identified came in.
The remains of a long-time fugitive who once topped the FBI's Most Wanted list have been recovered in North Dartmouth, Massachusetts.
Last month, the widow of the slain police chief sued Webb's wife, saying investigators had recently found a hidden room in her MA home where Webb may have hidden from authorities a decade or more after the shooting.
Police were led to Webb's body Thursday by his ex-wife, Lillian, who showed them where he was buried in her back yard in Dartmouth, Massachusetts.
Jones said Federal Bureau of Investigation agents told her that Webb may have hidden out in the home in short stints in the 1990s.
Thomas King III, an attorney for Mary Ann Adams Jones and Adams' two sons, had filed a civil lawsuit against Lillian Webb last month after learning that Webb had a hidden room inside her house and the room, accessible through a closet, still had a cane in it and evidence that someone who was injured had stayed there. She added that it's been a long time since she has spoken to Webb's wife.
"For nearly 37 years, the family of Chief Adams and the citizens of Saxonburg have been awaiting news of Donald Eugene Webb's whereabouts". The FBI is grateful to have been able to play a role in helping to resolve this case.
Webb's auto was found in Warwick, Rhode Island after the murder.
"The biggest question in the history of Saxonburg has been answered", said Saxonburg Police Chief Joseph Beachem in a statement.
