Susan Orfanos also said her son, Telemachus Orfanos, survived the Las Vegas mass shooting last year.
"My son was in Las Vegas with a lot of his friends and he came home. He didn't come home last night and I don't want prayers. I don't want thoughts. I want gun control, and I hope to God nobody sends me anymore prayers. I want gun control. No more guns," she said.
Orfanos was one of 12 people killed while attending a college night event at the Borderline Bar and Grill on Wednesday night.
