Wall Checked for Blood at Missing NC Teen's Home Search warrants issued in the disappearance of a North Carolina teenager said investigators seized stained flooring and baseboard's from the girl's home and were checking red-stained drywall for blood, a newspaper reported Thursday. Investigators also found a book about the disappearance of JonBenet Ramsey and plastic bag with magazines about the 6-year-old, who was found dead in her Colorado home in 1996, the Salisbury Post reported. Her killing was never solved. Authorities also took out two large knives covered with shrink wrap. Police are trying find out what happened to Erica Lynn Parsons, who was 13 when she was last seen in November 2011 and was reported missing July 30 by her older adoptive brother. Sandy and Casey Parsons have said their adopted daughter went to live with her biological grandmother in Asheville, but the Rowan County sheriff's office says that information hasn't checked out. "They're just looking for anything they can find," the couple's attorney, Carlyle Sherrill, told reporters Thursday. We want to help any way we can to find Erica. Authorities began searching the property on Wednesday. Sherrill also said Casey Parsons was hospitalized at Wake Forest Baptist Medical Center in Winston-Salem to undergo emergency surgery for what he said were complications with a medical problem. There was no word on her condition from the hospital Thursday afternoon. The warrants also say bank records show the Parsonses continued to cash support payments for Erica's care after the girl had left the home. The couple told reporters last week they continued to take the payments because Erica's health insurance was tied to the payments. Information from: Salisbury Post, http://www.salisburypost.com
