(Vancouver, WA)  --  Police are searching for a man accused of stealing a man's Nike Air Jordans at gunpoint in Vancouver.  Police say the victim posted an ad for the shoes on social media and received a reply from the suspect.  The two agreed to meet at the Vancouver Mall last night for the sale, but police say the suspect pulled out a gun instead of his wallet.  Police pursued the suspect in his car but called off the chase near the Expo Center after the suspect reached speeds up to 120 miles per hour on his way into Oregon.
