SAUGATUCK, Mich. (WOOD) — A swimmer went missing on Lake Michigan near Saugatuck Saturday.

The swimmer went missing around 6 p.m. about a mile north of the Saugatuck pier head, the Allegan County Sheriff’s Office said in a release.

Officials say the swimmer jumped off a boat and did not resurface. They say the swimmer was not wearing a lifejacket.

Multiple agencies, including the United States Coast Guard, searched for the swimmer for several hours until the search had to be suspended at night because of the dark, the sheriff’s office said.

Recovery efforts will resume Sunday.

The victim’s name has not yet been released.
