Dylan Steven Koshman was 21 when he disappeared from south Edmonton in the early morning of October 11, 2008. He had moved to Edmonton from Moose Jaw that May, was living with two cousins and working for a pipe-fitting company while planning an apprenticeship. Around 2 a.m. he was asked to leave a gathering at the house near 104 Street and 33 Avenue after an argument with his roommates. He walked out wearing only jeans, a dark t-shirt, and skateboarding shoes and has not been seen or heard from since.

His girlfriend reported him missing on October 15. The only item recovered was his wallet, found in a neighboring yard; there has been no activity on his phone or bank accounts. The Edmonton Police Service initially treated the case as a missing person investigation but later reclassified it to the homicide unit, describing the circumstances as highly suspicious and saying those present that night have not been fully truthful. The case is unsolved and suspended pending new information.

If anyone knew Dylan, was in that south Edmonton neighbourhood that night, or has information that could move the case forward, please come forward.
