The composite sketch of Jessica Heeringa's abductor.
NORTON SHORES, Mich. (WZZM) -- On a scale of one to ten, a witness says the sketch of a possible suspect in the abduction of Jessica Heeringa is a ten.
Investigators released the drawing Tuesday. They say a witness saw this man drive away from the gas station where Heeringa was working when she disappeared Friday night.
Heeringa, 25, was the clerk in the Exxon station on East Sternberg Road in Norton Shores. A customer found the station empty and called 911.
Police are now hopeful the sketch will lead to the suspect, the silver minivan he was driving -- and the safe return of Jessica Heeringa.
"With the sketch, now we are retracing some of our steps," says Norton Shores Police Chief Daniel Shaw. "We are taking the sketch out to some of those individuals we've already talked to, and are showing them the sketch."
Officers believe the sketch -- and other released clues -- will lead them to Heeringa's abductor.
"Someone knows this person," says Shaw. "That is a very good drawing. Someone is going to know who that is."
Surveillance video from a nearby business showed the minivan traveling northbound on Grand Haven Road Friday night, around the time of the abduction.
The effort to find Jessica Heeringa has spread across West Michigan. There are 28 digital billboards across the area drawing attention to her disappearance, including one on the east side of U.S. 131 near 10 Mile Road near Rockford.
