NORTON SHORES, Mich. (AP) -- A western Michigan police chief has released a second surveillance video showing a van that's believed to be connected to the disappearance of a 25-year-old mother and gas station night clerk.
Norton Shores Chief Daniel Shaw says the video may help investigators fill in the timeline of events of Friday night, when Jessica Heeringa was last seen.
Shaw says officers searched a state park Thursday evening after gunshots were heard in the area but found nothing. He says the shots probably came from hunters on the opening of turkey season.
Exxon Mobil Corp. and others have donated $15,000 for clues in the search for Heeringa. And Michigan legislators say they're looking for ways to protect convenience store clerks, including mandating surveillance video recording.
