589.26 Manner of service of writ.
The writ of habeas corpus may be served by delivering it to the person to whom it is directed, or, if that person cannot be found, by leaving it at the jail or other place in which the petitioner is confined, with any correctional officer or other person of proper age having charge of the petitioner. If the person upon whom the writ should be served hides, or refuses admittance to the party attempting to serve the writ, it may be served by affixing the writ in some conspicuous place on the outside either of the dwelling house, or of the place where the party is confined.
