Saturday marked the one year anniversary of Jessica Heeringa's disappearance.
One year later, and Norton Shores Police say they are still hopeful the 26-year-old mother is alive. Authorities have also released a timeline of events that led to her disappearance. The timeline includes a detailed statement from the gas station's manager and her husband. According to police the couple were riding their motorcycles on Sternberg Road, around 11pm, when they passed the Exxon Mobil and saw a silver Chrysler Town & Country turn off their headlights and drive behind the station. They pulled into a nearby lot, in view of the van... suspecting a robbery and that Heeringa might be involved. However, no suspicious activity occurred and the man drove off. He was described as a white male with wavy hair and wearing a red or orange sweatshirt. Neither the manager or her husband saw Heeringa in the van. Believing no crime had occurred, the two drove off themselves. Around 11:10 a customer called 911 when he didn't see a gas attendant inside the station. When police arrived they discovered that Heeringa's belongings were all left behind and there was no sign of a disturbance inside the store. A small droplet of blood was discovered behind the station, which was confirmed to be Heeringa's. The Exxon had no security footage at the time Heeringa went missing. However, video footage from nearby businesses show the van driving by . Throughout the investigation, 12 people have been of interest to the police. They say they receive tips everyday from all over the country and "...have no information to indicate that she is not alive."
