Bend Police responded to a report of a man who held up the College Way Chevron at 1400 NW College Way at gunpoint then fled with an undisclosed amount of cash about 7:50 a.m., May 9, said Sgt. Paul Kansky,

Officers and detectives were on scene within two minutes of the report, Kansky said, adding that Deschutes County Sheriff’s deputies responded with additional patrol units to assist.

Detectives launched an intensive investigation and developed leads that ultimately pointed to David Irwin Martin, 27, of Bend, as the suspect.  Martin was also the suspect in a “strong arm” robbery which took place April 25 at Franklin Avenue at the Bend Parkway.

Martin was spotted near the Bend Riverside Motel about 3:20 p.m. and was taken into custody without incident.  He was armed with a handgun at the time of his arrest, the sergeant said.

Further investigation into the gas station robbery identified an alleged accomplice who was interviewed at the police department and arrested Thursday about 11 a.m.  Nancy Elizabeth Carmack, 28, of Burns, Oregon, is lodged in the Deschutes County Jail and is charged with first-degree robbery and conspiracy to commit robbery.

Martin, in connection with the gas station robbery, is charged with first-degree robbery and conspiracy to commit robbery, and unlawful use of a weapon.  Other charges filed related to the April 25 “strong arm” robbery include second-degree robbery and conspiracy to commit robbery, menacing, third-degree assault, and second-degree theft.
