Investigators say Nathan Siqueiros, 19, sought out victims selling cell phones on craigslist and then would arrange a meeting to steal the victim's property.
One of the victim's spoke with Action News two weeks ago.
The woman says she arranged to meet a potential buyer at a shopping center in Southeast Fresno to sell him her iPhone.
She says the buyer showed up with a second suspect, and then he grabbed her phone and ran off with it.
