Why Did an 'Amber Alert' Catch California Off Guard?
(SAN DIEGO) -- Californians got a jolt overnight, and it wasn't from an earthquake. Many people were already in bed Monday night when alarms on their cell phones began sounding around 11 p.m. It was an Amber Alert for missing 16-year-old Hannah Anderson and her 8-year-old brother Ethan. And while this practice is familiar to some, it was the first time California law enforcement officials used the push notification system to alert the public of missing children via cell phone.
