WATTERSTOWN TOWNSHIP, Wis. -

A Muscoda man is dead after a single-vehicle crash in Grant County, according to the Grant County Sheriff's Office.

Deputies were dispatched to Highway 133 between Boscobel and Blue River, east of Kinney Lane, at 7:20 a.m. Friday when motorists reported a car in the ditch.

Investigators said the truck driven by Melvin L. Poole, 62, was eastbound on Highway 133 when it went into the ditch and struck a tree. Poole was dead when deputies arrived at the scene.
