Police believe Heeringa was abducted from the Exxon Mobil station where she worked on Friday night. There were no apparent sign of a struggle and her personal belongings were found inside the shop, police have said.

A gas station customer called 911 around 11:15 Friday night to report that the station was empty, but unlocked.

Norton Shores police on Wednesday released a second surveillance video of the minivan, taken from Coin Zone on Grand Haven Road, reports MLive. Initial surveillance video from the Old Homestead Tavern released by police showed what they believe to be the same vehicle.

"The video shows the silver minivan continuing to drive north on Grand Haven Road, less than a minute after passing the Homestead," Norton Shores Police Chief Daniel Shaw wrote in an email to the website. "We're not able to see the plate number or the driver, but it does help us by filling in more of the timeline of Jessica's abduction."

The van passes by the camera around 11:04 p.m., reports the website. Heeringa's last reported transaction at the station was at 10:55, according to the report.

Shaw told the Detroit Free Press that the second video is "a little bit better quality" than the first video.

Police have also released a sketch of a man they're seeking in connection with the disappearance of the 25-year-old mother.

Witnesses have described the driver as a white man, age 30 to 40, about 6 feet tall, with light brown wavy hair.

Police described Heeringa as 5-foot-1 and about 110 pounds.
