For information on Heidi Yewman’s book, visit Beyond the Bullet.On the one-year anniversary of the shooting of 19 people in a Tucson, Ariz., Safeway parking lot, about 30 people in Vancouver gathered to encourage gun safety and promote ways to prevent gun violence.The candlelight vigil was at St. Paul Lutheran Church and featured a survivor of the Columbine High School shooting in 1999.Andrea Bannister of Vancouver said she was a 17-year-old junior at Columbine when that Colorado massacre left 15 dead and 21 injured.She said her best friend, Corey DePooter, died and her boyfriend, Austin Eubanks, was wounded. Both were in the library.Bannister said she wanted to see what was happening when shots rang out and a substitute teacher refused to let her leave the classroom.“He saved my life by not letting me go,” she said. The teacher later led students down a hallway, out an exit and over a chain-link fence and told students to “run like hell.”“It still affects my life today, and it always will,” Bannister said. “I still have nightmares. … I am not a victim, but I am a survivor, and I always will be.”The Vancouver event was one of 65 on Sunday in 22 states, said Heidi Yewman, a writer who lives in Salmon Creek. She is a former Littleton, Colo., student and her teacher and coach, Dave Sanders, died in the massacre.
