A nurse who pleaded guilty to fondling a heavily sedated woman during an exam was sentenced to 12 years in prison on Tuesday.

Thomas Moore, 45, formerly worked at North Suburban Medical Center in Thornton. He fondled a patient who came into the medical center with a migraine on Nov. 8, 2015.

According to the Weld County District Attorney's Office, Moore also fondled five female patients at a UCH emergency room in Greeley from March 2014 to April 2015.

Those five women came forward after Moore was arrested in Fort Collins for allegedly sexually assaulting more patients there.

His most recent sentence will run concurrent to the 12 years Moore received for the Weld County crimes, where the district attorney there says Moore committed the crimes while administering morphine and other painkillers.

Senior Deputy District Attorney Chris Rossi said Moore targeted victims who were unable to react.

"He used his position as an ER nurse and took advantage of these vulnerable victims," Rossi said.

The victims said he also rubbed their shoulders, which made them uncomfortable.

In December 2015, he was also arrested for a sex offense against a child.
