Opening arguments begin Monday and a jury will begin hearing evidence this week against the man accused of killing federal intern Chandra Levy in 2001 — a case expected to be centered on the testimony of jailhouse informants.

Ingmar Guandique, 29, is on trial in D.C. Superior Court for Levy’s May 2001 slaying in Rock Creek Park. Prosecutors allege that Guandique raped and attacked Levy, a 24-year-old Federal Bureau of Prisons intern, while she was jogging in the park.
