--UPDATE: WAR MACHINE CAPTURED BY U.S. MARSHALS IN CALIFORNIA. FULL DETAILS HERE--

War Machine -- aka Jon Koppenhaver -- may have already been captured by police, had law enforcement officials not hung up on the neighbor who was trying to save a bloody and beaten Christy Mack (photos). In fact, the good Samaritan also alleges that cops hung up on Mack, too, then took their sweet time showing up to investigate.

By then, Koppenhaver was long gone.

"She came running to our door. We couldn't even tell it was a woman. My mother immediately called the cops and they hung up on her. Even Christy tried calling the cops, as well, and they hung up on her, too. It took the cops like 15 or 20 minutes to get to our neighborhood, which is just way too long. That's crazy. We had an emergency here."

When confronted by NBC about the phone call fail, Las Vegas metropolitan police offered no response.

War Machine, meanwhile, is still at large (see his criminal complaint here) while Mack -- along with a second victim -- remains hospitalized. The case has begun to draw national attention, which includes a manhunt from "Dog the Bounty Hunter."

Not a good week for the boys in blue.
