Investigators learned that a juvenile had escaped from Devereux Brandywine, a behavioral-health facility, on the day of the attack. Authorities believe he walked the 1.8 miles from the facility in Glenmoore until he came upon the woman's house.



The woman had no prior contact with him, they said.



Township Police Lt. Gene Babetski said that after the teen locked the woman in the closet, he poured bleach he found in the house on his sneakers, thinking it would disguise his presence there. Instead, the bleach caused footprints -- showing a distinct diamond pattern -- to be left on the cement floor outside the closet and on the second floor.



Police also found that one of the victim's credit cards had been used in Maryland on Feb. 22. Surveillance video from a store there showed the teen getting out of the woman's car and using her card. Among other evidence, police found the victim's phone at Devereux Brandywine.



The teen, originally from Thailand, had been living in Media and had returned to Devereux Brandywine two days after the attack but was then transferred to another facility.



District Attorney Thomas P. Hogan said detectives are checking with U.S. Immigration and Customs Enforcement to see if he is in the country legally.
