About 11:25 p.m., a 31-year-old man was walking on the trail near the Naval Postgraduate School when he encountered Robert Cepeda, 33, of Marina and the men began to argue, said Monterey Lt. Leslie Sonné.
When the fight escalated, Cepeda stabbed the 31-year-old, whose identity is not being released because of federal privacy laws, Sonné said.
About five minutes after they were called, officers found Cepeda on the trail at the edge of city limits near Roberts Lake. He was in possession of a knife that matched the description of the weapon used in the fight, Sonné said.
Dangerous place at night. Stay away.
