NEW ALBANY, Ind. (WHAS11) -- In recent days, the William Clyde Gibson III murder investigation has moved from inside the house, to a large storage container in the front driveway, to below ground.
Investigators were spotted Thursday using ground penetrating radar to look for objects buried in Gibson's backyard.
Evidence flags and marking paint could be spotted just yards away from where one of his three known victims was found buried six days ago.
As police worked, a woman who said Gibson "hit on her" looked on.
She said Gibson would target women in the neighborhood or in area bars.
"He offered pot. He'd offer liquor. That's how he lured them in pretty much," she said. "It's like he really knew the ones who partied and stuff. It's like he'd been watching them or stalking them. "
Gibson has so far been named a suspect in the murders of Christine Whitis, Karen Hodella and Stephanie Kirk. He has been charged with murder in connection with Whitis and Hodella. Authorities said they hope to charge him in Kirk's death.
Police are now trying to determine if Gibson may have been involved in the disappearance of Lauren Spierer,who went missing last June after a night of drinking with friends near the Indiana University campus.
Bloomington Police confirmed a detective has come to New Albany to see if there's any possible connection to the Spierer case, but that's being called a common tactic in any ongoing investigation, since Gibson has been known to target women.
As the search for evidence continues here, those who know Gibson are beginning to fear what might soon be unearthed.
"I be live there's a lot more more back there than what they found yet, i really do. and I just pray to God that they're found and laid to rest," the woman who knew Gibson said.
