A former U.S. Fish and Wildlife Service scuba diver from Bigfork has been sentenced to six months in federal prison for sexually assaulting a co-worker during a work trip in Glacier National Park.

U.S. District Judge Dana Christensen in Missoula sentenced Lawrence L. Lockard, 67, on Friday. Lockard earlier pleaded guilty to abusive sexual contact. He was ordered to pay $22,000 in restitution to the victim.

Prosecutors said Lockard and two co-workers were in Glacier Park for a scuba-diving trip at Quartz Lake in September 2015. Lockard and the woman slept in a cabin while another co-worker slept in a tent to avoid disturbing the others with his sleep apnea.

The woman said she awakened to find Lockard in bed with her, touching her inappropriately and trying to remove her clothing.

Lockard was interviewed by an National Park Service special agent and allegedly stated that he knew what he did was wrong and knew the victim was asleep.

Lockard was 17 years older than the victim and was her supervisor. The sentence was enhanced because Lockard knew at the time that the victim had been drinking, had taken prescription sleep medication and was asleep wearing earplugs when he assaulted her.

Judge Christensen also noted that despite Lockard’s lack of any criminal history, admirable employment record and good standing in the community, any type of unsolicited sexual contact is absolutely intolerable.

Lockard has retired from the Fish and Wildlife Service.

 This case was investigated by National Park Service Special Agent Justin Ivary and prosecuted by Special Assistant U.S. Attorney Adam Duerk.
