Jeremy Alexander Henness, 31, was shot and killed at the Pomona train station in the early morning of August 12, 2018. He and another man, Robert Salinas, were found unresponsive with multiple gunshot wounds and pronounced dead at the scene shortly after 4:30 a.m. A homeless passerby discovered the victims and alerted authorities.

Police arrested 40-year-old Christopher Matthew Peterson, an Amtrak engineer who was off duty, after he contacted the Ontario Police Department and said he might have been involved while intoxicated or under the influence. Investigators recovered a gun at Peterson’s home that was registered to him; he did not have a permit to carry a concealed weapon. Drug paraphernalia was found near the victims, and investigators said the shooting may have been drug-related.

Peterson was booked on suspicion of two counts of murder and was arraigned at the Pomona Courthouse on August 16, 2018. Both victims were known to be homeless, and outreach officers had previously contacted Henness to offer services. Does anyone have information about Henness’s movements that morning or about activity at the Pomona station around 4 a.m.?
