A federal jury on Tuesday found General Motors at fault in a rollover accident that killed a 14-year-old boy, awarding his parents $3.5 million following a two-week trial.

Bonnie Reynolds, now 48, was at the wheel of a 1995 Chevy Blazer on June 3, 2002. She and her son, Matthew, were riding south on Interstate 985 in Gainesville, Ga., when a drunk driver veered off the highway and lost control attempting to re-enter the highway and spun into the Reynolds’ SUV, according to a police report.
