A man accused of driving his car into oncoming traffic, killing a mother and her two children, was convicted of three counts of second-degree murder. Prosecutors said John Dunagan was driving at a high rate of speed on Highway 154 in October of 2019. His Chevy Camaro crashed into Vanessa Bley’s Chevy Volt, killing her and her children on impact. Dunagan faces 45 years to life when he’s sentenced next month.
