The man found fatally stabbed on Monday along a stream in Rock Creek Park has been identified as a 49-year-old man from Northwest Washington, according to D.C. police.

Police said Matias Molina was found about 7:50 p.m. Monday, lying along a creek bed in a wooded area near Beach Drive and Joyce Road NW. The site is just north of Military Road and about a mile north of a U.S. Park Police station.

Beach Drive is clogged with commuters during the week but is closed to traffic and used by bikers and joggers on weekends and holidays. It’s also near a popular picnic area. Police would not comment on a possible motive for the stabbing but said Molina was not wearing clothing consistent with outdoor recreational activities.

Acting D.C. police Capt. Robert Alder, commander of the homicide unit, said police have not determined whether Molina was killed in the park or elsewhere.

“We consider that area safe,” U.S. Park Police Maj. Keith Horton said.

Police are offering a $25,000 reward for information leading to an arrest and conviction in the slaying of Molina. Anyone with information is urged to call the department at 202-727-9099 or text the tip line at 50411.
