Crews were in and out of the backyard for hours Thursday, digging for clues. Investigators don't know how long the remains have been there or who they belong to.
They aren't saying if they know where Webb and his wife are.
Current Saxonburg Police Chief Joe Beachem drove 11 hours to be there Thursday.
"We're hopeful with the investigation," Beachem said. "It means a lot the town the size of Saxonburg, any town, it leaves a hole and it's the biggest question our town has had."
This is the longest-running cold case involving any police officer in the country.
The FBI is in the process of determining if the remains belong to Webb, as well as the cause of death.
