Deputy District Attorney Carolina Lugo said in closing arguments Tuesday that trucker Marcos Costa was guilty of gross negligence for continuing to drive his 18-wheeler down a mountainous highway when it was spewing smoke from its brakes.

She said he was stopped along the way and warned that the Angeles Crest Highway was too dangerous for his 25-ton rig to navigate. He was told to turn around but she said he did not.
