The final suspect in this week's terrible Tracy child abuse case has been nabbed. Caren Ramirez, 43, was picked up by police at her Berkeley home at around 9:30 p.m. last night. The case has received much media attention ever since a 17-year-old boy escaped from the home of Michael Luther Schumacher, 34, and Kelly Layne Lau, 30, on Monday via "vaulting over an 8-foot wall separating the couple's backyard and the parking lot of the In-Shape Sports Club in Tracy." He was found emaciated, nearly naked, and wearing a chain padlocked to his ankle. Schumacher and his wife, Lau, were arrested on Monday.
