According to other drivers, Nelson was swerving in and out of lanes at 90 to 100 mph when he rear-ended Patrick Mullane, who later died at the hospital. Witnesses say Nelson was acting erratically after the crash, jumping over freeway medians running up the mountain and then running back down. He told investigators he has schizophrenia, bipolar disorder, and ADHD and that he had not taken his medications in three days. Prosecutors are pushing to keep him in jail until trial.
