There´s a new report that D-C police have found a knotted piece of clothing that may have been used to restrain Chandra Levy. The Washington Post cites law enforcement sources, who say Levy´s stretch leggings, found near her remains, were knotted in a way that suggests they might have been used to tie her up. Police are refusing to confirm the report. Meanwhile, investigators have been scouring the steep slope in Rock Creek Park where Levy´s skeletal remains were discovered earlier this week. They´re looking for any evidence that could tell how she died, how her body got there and perhaps who killed her. The District of Columbia medical examiner has said he probably will not determine the cause of death until next week.
