Mo. Rev. Stat. § 521.340

Until a receiver is appointed, the attaching officer shall have all the powers and perform all the duties of a receiver under sections 521.010 to 521.650, and may commence and maintain actions in his own name, as such officer, on debts or evidences of debt attached. He may, in such case, be required to give security other than his official bond; but, if not so required, the sureties in his official bond shall be held liable, as in other cases of his official action.
