Corinne Coulier-Buchner, 27, of Montague Township was on her way to a doctor’s appointment when the pickup truck she was driving rolled over in Whitehall Township.
Muskegon County Sheriff Dean Roesler said Coulier-Buchner was last listed in critical condition Monday at a Grand Rapids hospital. Roesler said the unborn child did not survive the crash.
Roesler said her husband was heading to the appointment in another vehicle a few minutes behind her and stopped at the scene.
The sheriff said icy road conditions in the area likely played a role in the crash.
