Nate Ramo

Nate Ramo was a SWAT officer within the Gotham City Police Department, as well as a murder victim.

Batman: Arkham Origins
Nate Ramo, alongside most of his SWAT unit, was undergoing an investigation of corruption by internal affairs. Ramo decided to confidentiality reveal everything that he knew about his teammate's corruption. Unfortunately, one of his teammates, John DeMarco, learned of Ramo's attempted plea bargain, and murdered him via a hit and run just outside the GCPD. Batman, learned of the hit and run from a police dispatch via Officer Meyer, arrived at Burnley, investigated the event, and deduced DeMarco's involvement from paint residue from his car. DeMarco had briefly crashed into a wall due to losing control of the vehicle. Batman tracked DeMarco to a nearby building along with the other SWAT members and, after he interrogated DeMarco, left him to be arrested by the GCPD. The dialogue suggested that the other SWAT members were aghast at DeMarco for killing Burnley in front of the GCPD, as they realized it would likely make them seem even more guilty.
