Bank employee gave 'go signal' to boyfriend in violent attempted robbery, prosecutors say A bank employee gave a "go signal" to her boyfriend before a violent attempted robbery in Texas, prosecutors said in court on Wednesday. Shelby Wyse was the third person taken into custody in connection with Friday's assault in Houston that has left a woman critically injured. A fourth suspect remains at large. Surveillance video shows the victim parking at a gas station after making the withdrawal of $75,000 at Wallis State Bank. She was taking the money to her family's place of business, according to ABC 13. Video shows a man running up to her and trying to grab her purse. She holds onto the purse as she falls to the ground. As another man tries to help the victim during the violent struggle, a car driven by a suspect backs into the woman, and the assailants flee with some of the money.
