A U.S. Army Veteran is missing after going to possibly see someone about a car he found for sale on Craigslist.
Robert Polk, 22, was last seen on Saturday around 7 p.m. when he went to inquire about the vehicle and never returned home.
"I know something happened to my child," said Kayleen Jones, Polk's mother. "He had been looking for a car. We were looking on Craigslist."
Polk was meeting someone on Newstead about a black Mustang, but since he left to meet the seller, no one has heard from him.
Jones has been searching since her son went missing. She's put up posters, but says because he is an adult, others were slow to take his disappearance seriously.
"Now everyone wants to call and help. If you had helped the first day, we could have found him if he was hurt," Jones said. "It's almost been a week now. He could be in someone's field dead now."
Police are tracking Polk's cell phone and debit card. The debit card was used at a QuikTrip somewhere in the county.
Anyone with information is asked to contact the St. Louis Metropolitan Police Department at 314-444-5309.
