CLAYTON, Mo. (AP) – An organization that advocates for walkers and bicyclists in the St. Louis region is pushing for stiffer penalties for drivers who strike pedestrians.

The St. Louis Post-Dispatch reports that Trailnet wants more to be done to make sober drivers more accountable. The non-profit is specifically scrutinizing the deaths of 19-year-old LaTonya Williams and her 22-year-old boyfriend, Jermaine Byrd, who were fatally struck by a car last year while walking on a St. Louis County sidewalk. The driver wasn’t charged.

The accident was among several last year involving pedestrians in the St. Louis region in which no one was charged. Nationally, about 5,000 pedestrians are killed by drivers each year, accounting for 15 percent of all traffic fatalities.
