A former UPS employee in Arizona is accused of stealing a package containing a $160,000 diamond and trading it for $20 worth of weed, ABC-15 reports.

Walter Earl Morrison, 20, thought that the package he allegedly swiped while unloading cargo at Sky Harbor Airport in Phoenix contained cash, according to a probable cause statement obtained by The Smoking Gun. In fact, the package contained one pricey stone.

Authorities say the “half-baked bandit” traded the diamond for the equivalent of two joints of marijuana.

The diamond was later recovered and returned to its intended recipient.
