Police spent the day digging in the backyard of Webb's ex-wife's home in MA, where they found what is believed to be human remains.
Authorities have begun a dig in a MA yard to search for evidence in a decadeslong quest to find a fugitive wanted in the slaying of a Pennsylvania police chief in 1980.
The filing named Webb's wife, Lillian, and her son, Stanley.
"I'm not going to comment on any specifics on that", Quinn said. "I'm just so angry", Adams Jones said.
Mary Ann Jones, Adams' widow, told Channel 11 she didn't realize how emotional it would be to relive all of this.
Records from the Bristol County Probate and Family Court show Lillian Webb divorced her husband in September of 2005. Authorities believe Webb shot and killed Saxonburg police Chief Gregory Adams in December 1980 after Adams pulled him over for running a stop sign.
Butler County DA Richard Goldinger said he negotiated the immunity deal about 10 days ago. If he's still alive, he would be 85 years old. The deal was struck to achieve what we achieved.
The human remains found buried behind a MA home have been positively identified as a fugitive suspect wanted in connection to the decades-old, unsolved slaying of a Pennsylvania police chief, authorities said today.
"Nor have we been told who buried him", he said.
While she's grateful to law enforcement for never giving up, she says this really does not bring about closure.
The FBI posted a $100,000 reward for information leading to Webb's arrest or remains. He was first added to the list on May 4, 1981 and was removed on March 31, 2007.
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 FBI and Pennsylvania and MA authorities announced Friday the remains have been positively identified. State police in MA and Pennsylvania also were on hand for the dig.
But the answer has Adams' widow stunned.
Current Saxonburg Police Chief Joe Beachen was on scene of the discovery.
'Our thoughts are with the family and we hope this eases their minds, if even only slightly.
