Aunt Arrested in Case of Shackled Teen

Meanwhile, four children — ages, 1, 3, 11 and 9 — were also taken from the house, according to police.

Police arrested a husband-wife pair in the kidnapping and torture of a 17-year-old California boy. A third woman, Karen Ramirez, is also being sought in the case.

Police said the boy had previously been reported missing from a group foster home in Sacramento since 2007, but they had no idea how long he had been there or where his family was.

An unidentified neighbor told the Tri-Valley Herald that he had seen the boy playing with other children and thought he was a family member. The neighbor said he had limited contact with the couple, who had lived in the house for about a year.

"They appeared to be a normal family," the neighbor said. "We don't even know their last name. [The boy] wouldn't be allowed to talk to us when we'd see him outside or ask him questions."

Just this week Tracy, a city of about 80,000 one hour north of San Francisco, was named by CQ Press as the second-safest city in Northern California and the 46th-safest city in the nation.

Robinson said he had never seen a case like this in Tracy. "It's really abnormal here," he said.
