Mo. R. Crim. P. 33.13
Whenever the surety upon any bond shall desire to surrender his principal, he may procure from the clerk a certified copy of said bond, by virtue of which such surety, or any person authorized by him, may take the principal into custody. If a bond is forfeited for the failure of the principal to appear as required by the bond and the surety produces the principal prior to the rendition of judgment upon the forfeiture and the surety pays all costs and expenses caused by the principal's failure to appear the surety is discharged from further liability. When surrendering the principal to the sheriff the surety must deliver a certified copy of the bond and the sheriff shall take the principal into custody and acknowledge acceptance of the principal in writing. Any principal so surrendered may be conditionally released pursuant to Rule 33.01.
