Investigators Search Nearby Pond for Theresa Parker

      Homeowner Ross RobinsonGBI investigators served a search warrant Saturday at the home that Theresa Parker had shared with her estranged husband, Lafayette police sergeant Sam Parker. 
   Investigators also searched the property of Ross Robinson, who lives just down the road. Ross Robinson, "I saw lot of search people looking in the lake. They had their dogs out looking, they showed some interest in the lake up there."
   Robinson says the pond located behind his home is almost 25 feet deep...he says investigators were in the area for more than six hours.
   "It's got a lot of trees, they couldn't really search it that great, they said they might have to pump it."
   Meanwhile...friends and family continue to pray for Theresa's safe return, eventhough recent searches have yielded no clues.
   Sheriff Steve Wilson says Parkers last cell phone call came from an area of South Walker County. Patricia Burrell has been a friend of Parker's for more than 20 years. She joined more than 200 volunteers who spent Saturday searching the area.
   Patricia Burrell, "We were there for about 3 hours, up and down the roads looking at old buildings, all along the creek, anything we could find that would give us an idea if she'd been out in the area."
   Burrell says her friend would not just leave and cause her loved ones so much worry.
