NORTON SHORES, Mich. - One month after Jessica Heeringa disappeared from a west Michigan gas station, police believe the missing mother is still alive.
Police have sorted through more than 2,000 tips, but have not found the 25-year-old.
Norton Shores police Chief Dan Shaw said Friday that while the tips "have slowed down somewhat," some of them are high-priority tips that are worth checking out.
Heeringa disappeared April 26 before she was set to close the station in Norton Shores, near Muskegon. Police say there's no indication of a robbery. A task force is investigating.
Police have released a description of a silver minivan and a man seen in the area.
Tests done on droplets found at the gas station have come back positive for Heeringa's blood.
Police have released a description and composite sketch of a man suspected of kidnapping the gas station cashier.
He is a white male, about 6 feet tall, between 30 and 40 years old, with wavy hair parted in the middle.
