A Michigan police chief released a second surveillance video showing a van that's now believed to be connected to the disappearance of a 25-year-old mother and gas station night clerk.

Norton Shores Chief Daniel Shaw stated this week that the video could help investigators fill in the exact timeline of events from the night of April 26, when Jessica Heeringa was last seen according to a report by the Associated Press.

Shaw said that officers searched a state park on May 2 after gunshots were heard near the area, but didn't find anything that could help with the case. He believes that the shots probably came from nearby hunters as it was the opening day of turkey season.

On April 30, police released a sketch of a man who they're now looking to question according to the Associated Press.

The second surveillance video was released on April 29 from a local bar near the suspected abduction site. Both videos which have been released show a silver or gray Chrysler minivan speeding away from the Exxon Mobil gas station.

Heeringa was on duty at the time of the kidnapping according to the Associated Press.

Exxon Mobil and others have donated $15,000 for clues in the search for Heeringa.
