(AP) — A 49-year-old Lincoln woman has been found guilty of stealing nearly $40,000 from a clinic for recovering addicts.

Lancaster County District Judge Jodi Nelson on Tuesday found Becky Nannen guilty of theft by unlawful taking.

Prosecutors had accused her of stealing $39,925 from 2008 to 2011 when she worked as an accountant at First Step Recovery in Lincoln. The embezzlement was discovered by a staff audit.

First Step Recovery helps people addicted to drugs, alcohol and gambling as well as those with eating disorders.

Nannen will be sentenced Aug. 1. Her prison sentence could range from one to 20 years.
