Details of Disappearance

Bokslag was last seen in South Salt Lake, Utah on June 6, 2022. That day at 11:40 a.m. he left his apartment in the 3800 block of South West Temple. He was carrying the backpack he normally took to work; since 2019, he'd had a summer job as a watershed ranger at the Salt Lake City Watershed.

On the morning of his disappearance, Bokslag was supposed to do a virtual job training session, but he never logged in to complete it. He never showed up for work and was never seen again. His handgun, a 2022 Sig 9mm pistol, could not be found after his disappearance and he may have taken it with him. The work backpack he carried at the time of his disappearance usually contained a pair of Swarovski binoculars, a first aid kit, a Gerber brand multi-tool in a carrying case, and a bottle of water.

The last place his cellular phone pinged was near 2100 South and 300 West in Salt Lake City, Utah; at this point the phone was apparently shut off. Around that time, $100 was withdrawn from Bokslag's bank account. There's been no activity on his bank account, phone or social media accounts since then.

Two days later, on June 8, Bokslag's parents reported him missing to the police after they were unable to contact him.  That same day, his silver and black 2012 Suzuki SX4 hatchback with the Utah license plate E068FE was found in a remote area of Summit County, Utah, near the Wyoming border.

It had not been hidden, but its license plate had been removed. The keys were missing and there were few fingeprints and no evidence of foul play. There was no sign of Bokslag at the scene and he has never been heard from again.

Bokslag graduated from Jordan High School in Sandy, Utah in 2010 and joined the Marines later that same year. He served out his contract in 2014. The circumstances of his disappearance are unclear.
