Police are searching for two men they believe are connected to the abduction of missing Michigan mom Jessica Heeringa, who vanished Friday night in the middle of her shift working as a gas station attendant.
Police on Tuesday released a sketch of the man they are looking for, while eyewitnesses say they noticed another man "being real flirty"
with Heeringa shortly before she went missing from the Norton Shores, Mich., Exxon station where she was working the late shift alone.

Christian VanAntwerpen, an employee at a store adjacent to the gas station where Heeringa was working, said he noticed a man in a silver minivan approach the 25-year-old while she was at a gas pump.
"He was just like, 'Hey, what are you doing over here? Aren't you supposed to be inside?' Just kind of being real flirty, weird about it," VanAntwerpen told ABC News. "It was just bizarre that he seemed to be actively looking for her, like he knew her and then had this attitude that he wanted to have a conversation with her and then conduct business, and that is what seemed really out of place to me."
Surveillance footage shows a gray minivan — similar to the one VanAntwerpen saw — traveling northbound away from the Exxon station Friday night. Witnesses described the driver as a white male, 6-feet-tall, with a medium or heavy build.
Police also released the 911 call from Friday around 11:15 p.m., when a concerned customer reported an eerily empty gas station.
"There's nobody here. There's a car here. There's another car out in front, but it's very suspicious why there's nobody here," the caller said.
Police said Heeringa's last transaction took place at 10:55 p.m., leaving a small window of time between when she was last known to be in the store and when she was reported missing.
"There is no sign of a struggle in the store, so it's possible she knew who the person was as a customer or as an acquaintance," Norton Shores Police Chief Daniel Shaw told ABC News.
