Albuquerque police say a robbery suspect may have left a piece of his finger behind at a crime scene

KRQE-TV reports (http://bit.ly/yXFEMG) that police arrived to an Albuquerque smoke shop after a report of shots fired at a robbery.

Authorities say the suspect fled, but they believe he left behind his severed fingertip.

It's unclear how the fingertip became severed. Contrary to earlier reports, police now say they don't believe the suspect may have shot it off himself.

There wasn't enough of the finger left to pick up a fingerprint, but police have submitted a request for blood work to be done on what was left behind.

Police also say they contacted all hospitals in the area, but none had any patients with gunshot wounds or other hand injuries over the weekend.

No arrests have been made.
