Roberto Gutierrez Cruz was 22 when his body was found in a wooded area behind the 18200 block of Contour Road in Montgomery Village, Maryland. A passerby discovered the body on the afternoon of November 2, 2015; an autopsy determined he died of multiple gunshot wounds and his death was ruled a homicide.

Investigators say Gutierrez Cruz had been in that same wooded area the night before, around 10:30 p.m. on November 1, with several other people. Police suspected a gang-related motive and reported the suspects had ties to MS-13. Within days three suspects were arrested and charged with first-degree murder and use of a firearm: 18-year-old Juan Espinal Rapalo (arrested November 4), 17-year-old Luis F. Avelar Morales (arrested November 5 and charged as an adult), and 19-year-old Daniel Adonai Ramos (arrested November 7). Detectives recovered the handgun used in the killing.

In late December, investigators charged a fourth suspect, 18-year-old Edwin E. Reyes-Martinez, alleging he helped conceal the firearm; he was charged as an adult with being an accessory after the fact to first-degree murder and possession of a handgun.

Did anyone in Montgomery Village see or hear anything in that area on the night of November 1 that could help the case?
