HOUGHTON LAKE, Mich. (AP) - Michigan State Police say autopsies show a couple found dead in a northern Michigan swamp died of hypothermia. They announced the autopsy results Tuesday for 34-year-old Jeff Hurley of Prudenville and 19-year-old Alexandria Foust of Cadillac. They said toxicology reports show both had been under the influence of methamphetamine when they died. The couple went missing in November 2017. A truck belonging to Hurley was found that month stuck in mud. The bodies were found in the Dead Stream Swamp area of Missaukee County in late March.
