Locke Senior High School

Locke High School English teacher Katy Bridger tried to give her fifth-period seniors a test while Byron Gordon sharpened pencils noisily, Deon Crockett wandered the room complaining at full volume and a girl cursed just as loudly at Deon for being rude. Daniel Dominguez dozed in the back. Pressing on, Bridger, a 23-year-old recent political science graduate from Tennessee, told students to put away their cellphones and iPods. One student demanded to know why, muttering the F-word.
