On the night of January 19, 2025, 17-year-old Mason Sheets was found fatally shot inside a disabled vehicle near the intersection of South Business 54 and Commons Drive in Fulton, Missouri. Fulton police arrived after a call at about 11:51 p.m.; Sheets had multiple gunshot wounds and was pronounced dead at the scene. A juvenile female who was present was taken into custody; authorities have not released details about her involvement because of her age.

Mason was a senior at Fulton High School and one of the first students accepted into the Fire Fighter Training Program run with the Fulton Fire Department. Friends and classmates remembered him for his kind heart, enthusiasm, and love of camping and fishing. Investigators generated more than 250 leads and activated the Mid-Missouri Major Case Squad; they believe the motive was likely tied to a transaction involving an illegal substance.

The probe also produced an arrest: Treyvale Cain-Raybon of Columbia was charged with hindering the prosecution of a felony after allegedly suggesting in an Instagram group chat that the reported stolen vehicle be burned and disposed of in a lake; he was arrested January 28 and later posted a $3,000 bond. Does anyone who knew Mason or saw activity near South Business 54 and Commons Drive on January 19 have information to share?
