The makeshift rope was found "still tied to the heater in her bedroom and hanging down along the outside of the building," Chief Tom Nolan said Wednesday evening. "The makeshift rope extended from her window down to about 10 feet off the roof. It is our belief that she fell while exiting the window, because we do not believe the makeshift rope would have remained intact with her weight on it."
Custer confirmed the teen was under the care of Montgomery County's Office of Children and Youth, which contracted the case to Ft. Washington-based Access Services.
"We are confident that all our protocols have been followed," Custer said. "Access has a very good reputation with their foster parent program."
The organization's website says it provides "support services for individuals with special needs in Southeastern Pennsylvania."
Mary Williams, who lives in the same apartment building, five floors below the victim and foster parents, said she chatted with them when doing laundry or as they went in and out of the building.
The 14-year-old was "a good girl. She was friendly to everybody," Williams said, but acted awkwardly at times. "I never asked the foster mother about her mental state, but [the girl] seemed like she was slow."
Williams last saw the victim on Sunday, in the basement laundry room.
"I didn't hear her come in, but when I turned around she was just standing there staring at me. I said, 'what's wrong?' She said, 'oh, no there nothing wrong. I was just looking.' "
Williams said the foster parents were "good Christian people" and the wife, in particular was "nice, loving, warm."
The Marquis Apartment complex has been the site of numerous incidents in the last several years.
Raghunandan Yandamuri, 27, is accused of fatally stabbing Satayrathi Venna, 61, in October, then kidnapping and killing Venna's granddaughter, 10-month-old Saanvi Venna. Both victims and the suspect were residents at the Marquis, where the crimes took place.
In 2011, residents of 400 units at the Marquis lost water when a pump broke Christmas morning. Officials deemed three buildings to be "unfit for habitation" until repairs were made.
A year earlier, in 2010, Montgomery County authorities arrested Charbel Pita Rosales, nicknamed the Kingpin of Prussia, and accused him of operating a drug gang out of the complex. Rosales was convicted last year of numerous felonies related to the drug operation and is awaiting sentencing.
