A driver whose pickup truck plowed onto a youth soccer field, killing a young boy and a father, will not face criminal charges following an investigation, prosecutors announced.

Last month, the driver, who has not been identified by authorities, drove into players and spectators at the Stryker Sports Complex in Wichita, Kansas.

Cole Adrian, 6, and Nicholas Schafer, 35, were both killed and several others were injured in the Oct. 17 incident.
