Did Aliens Abduct an Ionia Man Last Week?

A 23 year old Ionia man woke up by the side of the road one evening last week with no idea how he got there.  Alcohol and drugs are not believed to have been factors in his mysterious journey from his home to the roadside a few hours later.  Get more details on the story here.

Theories?

I believe Internet commenter wannabe2 makes a reasonable suggestion at the end of the MLive article: "Agent Mulder says to look for the alien chip in the back of his neck or his left forearm."
