Michigan police investigating the mysterious disappearance of a mother who works at a gas station are now calling it an abduction case, while her family is pleading for her return.

Jessica Heeringa, 25, vanished Friday night around 11:15 p.m. during her late shift at the ExxonMobil gas station in Muskegon.  Her purse, belongings and vehicle were left behind, and police were notified after a customer called 911 and said no employees were at the station, Fox 17 reports.

“She’s a good mom. She loves her family…she wouldn’t just leave,” April Dyer, Heeringa’s future sister-in-law, told the station.

Heeringa has a 3-year-old child, and Dyer said her fiancé is distraught.

Norton Shores Police said Sunday that they are searching for a silver Chrysler minivan driven by a white male, who is around 30 years old and described to be six feet tall.
