A 26-year-old woman is dead after an all-terrain vehicle crash in the Branch County, Michigan, community of Union Township on Friday night.

According to the Michigan State Police, the collision happened around 9 p.m. along Sullivan Road near Braucker Road. Investigators said the woman, from Union City, Michigan, was operating the ATV westbound on Sullivan Road when she lost control of it after passing another vehicle.

The woman was pronounced dead at the scene despite life-saving efforts. According to officials, she was not wearing a helmet at the time of the crash and alcohol "is believed to be a factor."
