A Tulsa man was sentenced to 20 years in prison, after pleading guilty to robbing four dispensaries.

Video shows Matthew Spears and two other men in Eufloria last January.

Two of the men took cash and weed, while the third put a gun against the clerk's head.

Spears pleaded guilty to that robbery and three others.

Spears' brother Thomas, and Isaiah Williams are also charged. Their cases are pending.
