BOISE, ID (MyBellinghamNow.com) – An Idaho prison inmate and an accomplice have been taken into custody following an ambush at a Boise hospital, and investigators are looking into whether the men killed two people while on the lam.

Police said the accomplice, Nicholas Umphenour, is suspected of shooting two corrections officers in the ambulance bay at Saint Alphonsus Regional Medical Center early Wednesday. He and inmate Skylar Meade drove off after the shooting in a gray 2020 Honda Civic with Idaho plates.

The two were apprehended in Twin Falls Thursday afternoon, about 130 miles from the hospital.

Authorities said they are also investigating two homicides in Nez Perce and Clearwater counties – places where the Honda Civic was later found. One of the crime scenes had shackles there, or what an investigator said are the kind that would be used for restraint of the inmates.

Officials described Meade as a white supremacist gang member who was sentenced to 20 years in 2017 for shooting at a sheriff’s sergeant during a high-speed chase. Umphenour was released in January from the same correctional facility that Meade was imprisoned – Idaho Maximum Security Institution in Kuna – and authorities said Umphenour and Meade were housed together while imprisoned.

Meade was taken to the hospital Tuesday night after he engaged in self-injurious behavior. The attack occurred in the hospital’s ambulance bay as Idaho Department of Correction officers prepared to bring Meade back to prison a little after 2 the next morning.

One officer shot by the suspect was in critical but stable condition, police said, while the second wounded officer had serious but non-life-threatening injuries. A third corrections officer was mistakenly shot by a responding officer. One of the injured officers has since been released from the hospital, and the other two remain in stable condition.
