The single fatality in yesterday's early morning collision at Octavia and Oak has been identified as 52-year-old UCSF professor Dr. Kevin Mack, a psychiatrist, who was on his way to work. Mack was ejected from the UCSF shuttle bus that was involved in the crash and landed underneath the big-rig vehicle transport. He was pronounced dead at the scene.

Witnesses are reporting that the UCSF shuttle may have run a red light at the intersection, precipitating the crash. This remains under investigation. Supervisor Ross Mirkarimi, who represents the district in which the collision occurred, seems to be defending the layout of Octavia as a "fabulous boulevard."

Mack is survived by his husband and their two children. Three other passengers of the shuttle bus were injured and taken to the hospital for treatment. They ranged in age from 58 to 85 years old, and we're guessing they were also UCSF employees, given the early hour.
