GARLAND (CBSDFW.COM) – Police in Garland have found the car that was used in a violent robbery involving a child last week in University Park.

They arrested the driver, a woman named Tiffany James, and charged her with an unrelated robbery.

Investigators said they hope James will lead them to the woman who held a knife to a 7-year-old boy’s throat, as she robbed his mother last Friday at the Snider Plaza Shell Station in University Park.

Police said shortly after the robbery, the suspect attempted to use a stolen credit card at a department store. Investigators were able to pull security footage of the person they believe is responsible and the car she used to get away in after the robbery.
