W. Va. R. Crim. P. Mag. Ct. 4

(a) Issuance. — If it appears from the complaint, or from an affidavit or affidavits filed with the complaint, that there is probable cause to believe that an offense has been committed and that the defendant has committed it, a warrant for the arrest of the defendant shall issue to any officer authorized by law to execute it. The magistrate may restrict the execution of the warrant to times during which a magistrate is available to conduct the initial appearance. Within the discretion of the magistrate a summons instead of a warrant may issue. More than one warrant or summons may issue on the same complaint. If a defendant fails to appear in response to the summons, a warrant shall issue.

(b) Probable Cause. — The finding of probable cause may be based upon hearsay evidence in whole or in part.

(c) Form. —

(1) Warrant. — The warrant shall be signed by the magistrate and shall contain the name of the defendant or, if the defendant's name is unknown, any name or description by which the defendant can be identified with reasonable certainty. It shall describe the offense charged in the complaint. It shall command that the defendant be arrested and brought before the nearest available magistrate of the county in which the warrant is executed.

(2) Summons. — The summons shall be in the same form as the warrant except that it shall summon the defendant to appear before a magistrate at a stated time and place.

(d) Execution or Service; and Return. —

(1) By Whom. — The warrant shall be executed by any officer authorized by law to arrest persons charged with offenses against the state. The summons may be served by any person authorized to serve a summons in a civil action.

(2) Territorial Limits. — The warrant may be executed or the summons may be served at any place within the state.

(3) Manner. — The warrant shall be executed by the arrest of the defendant. The officer need not have the warrant at the time of the arrest, but upon request the officer shall show the warrant to the defendant as soon as possible. If the officer does not have the warrant at the time of the arrest, the officer shall then inform the defendant of the offense charged and of the fact that a warrant has been issued. The summons shall be served upon a defendant by delivering a copy to the defendant personally, or by leaving it at the defendant's dwelling house or usual place of abode with some person of suitable age and discretion then residing therein and by mailing a copy of the summons to the defendant's last known address.

(4) Return. — The officer executing a warrant shall make return thereof to the magistrate or other officer before whom the defendant is brought pursuant to Rule 5. At the request of the attorney for the state any unexecuted warrant shall be returned to and canceled by the magistrate by whom it was issued. On or before the return day the person to whom a summons was delivered for service shall make return thereof to the magistrate before whom the summons is returnable. At the request of the attorney for the state, made at any time while the complaint is pending, a warrant returned unexecuted and not canceled or a summons returned unserved or a duplicate thereof may be delivered by the magistrate to an authorized person for execution or service.
