EDMOND, Okla - It all began on Craigslist when a student was trying to unload a used iPhone, according to police.
The student agreed to meet the prospective buyer outside an apartment complex on E. Ayers in Edmond.
According to police, the two UCO students were completing their transaction when a stranger came out of nowhere and robbed them both at gunpoint.
He allegedly stole their wallets and smartphones before disappearing into the darkness.
Felicity Diaz isn't too surprised. She said this complex is an ideal location for crimes of opportunity.
"It's dark and secluded. You don't see many street lights because of the trees. It's pretty dark. You gotta stay cautious," Diaz said.
Kendyn Webster has been victimized twice since moving here. His car was burglarized in the parking lot.
"It's very close to the college and you wouldn't expect it in an area like this," said Webster.
Authorities warn all college kids to be alert, travel in packs and avoid short cuts.
If you plan to buy or sell anything online, take your transaction to a safe place.
It can't get any safer than the police department.
"Obviously, it's being video recorded and there are people here all the time. It's just a safer environment," said Jenny Monroe, with the Edmond Police Department.
