A US family is desperately searching for answers after a young mother was abducted from a petrol station while working the late shift.
Authorities have pinpointed a 15-minute window in which Jessica Heeringa, 25, vanished from the Exxon Mobil station at Norton Shores, a small town in the US state of Michigan, last Friday night.
The station did not have any surveillance video installed so there is no CCTV vision of what happened that night.
Ms Heeringa made her last sale at 11pm, local police said.
At 11.15pm, a concerned customer called police reporting that the petrol station had been left unattended.
Ms Heeringa left behind her car keys and purse. On the counter sat the cleaning supplies she normally uses when tidying up at the end of the night.
Investigators are relying on tips to help them piece together what happened during the 15-minute time frame Ms Heeringa went missing.
It appeared robbery was not a motive and the store's cash drawer was left untouched, police said, adding that there was no sign of a struggle.
"She was going to get out in 15 minutes," Shelly Heeringa, Jessica's mother, told ABC News. "In 15 minutes that store would've been closed and she would've been on her way home."
The mother added that someone saw her daughter "walk out of the store with this guy like there was no problem," but when they got to his van, a struggle ensued.
Investigators are searching for a grey minivan seen behind the station shortly Ms Heeringa went missing.
The driver is described as a white male, about 30-40 years old, wearing a bright red or orange sweatshirt.
The mother said she told her daughter several times that she worried about her working late by herself.
"She said, 'Mum, don't worry. I can handle anybody,'" Shelly Heeringa said.
