Blood dries on the quiet, deserted platform at the South Capitol Rail Runner station on Tuesday afternoon, the brownish-red stain the only remnant of a hectic Monday at this usually bustling Santa Fe hub. Around 3:45 pm Monday, two men were shot and one was killed in what police now say was an "isolated incident" and not a "random act" of violence.

David Hernandez, 24, of Santa Fe, died at the scene before paramedics were able to reach him. The second victim, 38, is still in critical condition at a local area hospital. Santa Fe Police Department Capt. Anthony Tapia declined to identify the surviving victim, though families of both men have been notified. He would not provide a reason.

Tapia also declined to say how many times and where each victim was shot, citing an active investigation.

Tapia would not say whether police have any suspects; no arrests have been made.

Detectives have made some small steps forward in the investigation: The shooter was on foot on the uncrowded platform before he opened fire on Hernandez and the second man, Tapia tells SFR. Law enforcement is still investigating whether there were multiple guns or shooters and if nearby surveillance cameras caught the crime.

It's also not known whether the victims were waiting for the train, which was picking up passengers at the Santa Fe Depot, the Rail Runner's northernmost station.

Following a tip from the community, police were looking for a small, four-door sedan as a "vehicle of interest" with two occupants inside that witnesses saw near the scene on Monday. Tapia said later Tuesday that authorities had "scratched the search for the car off of our to-do list," but he would not say whether it had been located.

Augusta Meyers, a spokeswoman for the Rio Metro Regional Transit District, tells SFR that while she's not sure what the surveillance cameras on the Rail Runner platform caught, the department has turned it over to SFPD.

Meyers says she can't think of a time when anything like this happened on a Rail Runner platform.

"I haven't heard of any [other homicides] in my 15 years here," Meyers tells SFR.

This is the fifth reported homicide within Santa Fe's city limits in 2021. The murder of Hernandez has brought the total of suspected murders above 2020's reported three and on track to catch up to 2019's seven reported homicides.

Anyone with information on this incident is asked to contact Detective Rebecca Hilderbrandt by calling 505-955-5265.
