BEND, OR -- A former Oregon State Police crime lab analyst has pleaded guilty to stealing controlled substances she was supposed to be processing as evidence.

Officials say 36-year-old Nika Larsen worked as a forensic scientist at the Bend lab. She was accused of stealing items from evidence that had been submitted by various law enforcement agencies.

Larsen agreed to a plea deal and could face three years in federal prison when she's sentenced in December.
