DES MOINES, Iowa (AP) — Des Moines police have charged a driver who investigators say may have caused another driver to swerve his car and plunge over a concrete wall to his death in a parking lot below. The Jan. 27 crash killed 32-year-old Grant Stokka and injured his 8-year-old son. Police say another vehicle entering traffic may have caused Stokka to abruptly change his direction of travel and go over the wall.
The charges announced Thursday indicate that investigators suspect 26-year-old Des Moines resident Tessa Mullen was driving the other vehicle.

She’s charged with failure to yield, reckless driving and with committing a driving violation that resulted in death.
