The family of missing woman Naomi Irion traveled from South Africa to Nevada this week to assist in the search for their 18-year-old daughter.

Irion was last seen in a Walmart parking lot in Fernley, Nevada, where she typically parked her car and took an employee bus to her job at a Panasonic factory, on March 12. The FBI said she was "abducted" from the parking lot "by a nondescript male."

Security camera footage released by the Lyon County Sheriff's Office on Tuesday shows a potential suspect in her kidnapping – a male wearing jeans and a gray, hooded sweatshirt – walking from a nearby homeless camp into the Walmart parking lot. Authorities said in a March 15 Facebook post that the suspect got into the driver's seat of Irion's vehicle and left in an "unknown direction with Naomi in the passenger seat."

In a March 19 update, authorities said the suspect can be seen "at times … walking directly in front of vehicles and their headlights."

Authorities said the suspect is believed to be driving a new, dark blue or black Chevy 2500 truck.
