SAN FRANCISCO — Passengers on a crowded San Francisco commuter train were so absorbed in their phones and tablets they didn't notice the gunman until he randomly shot and killed a university student who had just exited the train, authorities said.
The man drew the gun several times on the train, with surveillance video showing him pointing it across the aisle without anyone noticing and then putting it back against his side, authorities said.
Before that moment, footage showed the man pull out the .45-caliber pistol and once wiped his nose with the hand holding the weapon, District Attorney George Gascon and police Chief Greg Suhr said.
"On the surveillance video we have, everyone is looking at their cellphones and personal devices and nobody notices," Gascon said recently when announcing murder charges against Nikhom Thephakaysone in the Sept. 23 fatal shooting of Justin Valdez, 20, a student at San Francisco State University. "I find that to be very concerning."
