911 call may cast doubt on conviction in Chandra Levy murder

More than a decade after Chandra Levy's disappearance and death, a startling new clue came out in court Thursday that could raise doubts about the 2010 murder conviction of Ingmar Guandique.

In court, there was mention of a 911 call from one of Chandra Levy’s neighbors on the day of her disappearance. The neighbor reported she could hear a woman screaming from her apartment.

The defense has requested access to the 911 call and are questioning why prosecutors never revealed information about the call. It could raise questions into the prosecutor's case that said Guandique attacked Levy at random in Rock Creek Park.

Shortly after Levy's disappearance, former D.C.police chief Charles Ramsey referenced a 911 call but did not believe it was related. It was never mentioned in court.

A judge closed recent hearings, though documents related to some of them were unsealed in February. The records show that government prosecutors asked to seal a Dec. 18 hearing to talk about information they learned about after Guandique was sentenced.

The records also show defense attorneys believe the information calls into question the testimony of a witness and that they plan to ask for a new trial.

Levy disappeared in 2001. Her remains were found in 2002.
