Advocate: Disabled adults can be ‘walking targets’

In the case of Herbert Knowles, one of the people found in the basement, a case worker learned after he was reported missing in Norfolk, Va., in 2008 that checks were being diverted to Philadelphia. Police went to the given address, where Weston, now 51, had lived from about 2003 to 2005. They were told Knowles did not live there, and the trail apparently stopped.
