PHILADELPHIA (CBS) — For the first time, CBS 3 heard from the family of Edwin Sanabria. The 31-year-old is one of the mentally challenged adults held captive in a basement. Sanabria’s family wants to know if any of the children in Weston’s care, who are now in the foster care, are related to them. DNA tests results are still pending.

Robert Sanabria came by CBS3 to watch video of what might be his niece. The video came from a woman who says she lived next door to Linda Weston for about six months back in 2007. Weston told her neighbor the child, known as “Little L”, was hers. Sources say, it could be that of basement victims, Tamara Breeden and Edwin Sanabria.

“I thought he was probably dead,” said Edwin’s brother Robert. “I had nightmares about it, waking up, crying at times, wondering where he’s at.”

Robert Sanabria and his father Ivan, who speaks little English, say they and other family members visit the personal care facility where Edwin is staying. Last Wednesday they learned of the alleged abuse Edwin and three other mentally challenged adults suffered in the Tacony basement.

“He’s been shot in the foot with bee bee guns,” said Robert Sanabria. “He’s been sliced. He has scars all over his body, gashes from sharp objects.”

Edwin’s father says he is in a lot of pain and feels anger and sadness for the alleged abuse inflicted by Linda Weston and three others.

Robert, who is two years younger than Edwin, says since they were children, he’s always felt like the protector; now he says he is, without a doubt, willing to shield his brother from all things negative, for good.
