Authorities were back out on the private property off East Orem Friday morning to continue their search for a body. Cain was just 17 years old when she disappeared in 1997.
Officials also confirmed that William Reece, 56, now is being investigated in connection to Cain's disappearance. Reece, who is currently behind bars for an unrelated aggravated kidnapping conviction, was released recently on a bench warrant to Galveston County. On Wednesday, he was on the property where authorities are digging. He used to live less than four miles away.
Reece also was the primary suspect in the death of Laura Smither, the 12-year-old girl who vanished while jogging near her Friendswood area home on April 3, 1997. Her body was found later that month in Pasadena.
Smith and Cain's disappearances were just four months apart.
"We continue to have hope she's not dead. We're praying she's not," Cain's father, C.H. Cain, said.
The Cain family believes she might have been taken across to Mexico all those years ago. Reece could have the answer.
