A man has been sentenced for his role in the mailing of methamphetamine to Hawaii in two mannequin heads.

Zebulon Bates was sentenced Thursday to 52 months in prison and has until next month to start serving the time because his girlfriend is about to give birth to their fourth child.

Federal documents say authorities intercepted the package from California last year at a UPS sorting facility. Bates says he planned to sell four ounces of the crystal meth himself.

It was the second case involving the mailing of meth to Hawaii in mannequin heads. Prosecutors say they haven't been able to directly link the two.
