Save this story for later. In September, 2009, a card dealer named Evie Oquendo arrived at her apartment, on the far east side of Las Vegas, with groceries for her fifteen-year-old son, Tanner Chamberlain. Tanner, who struggled with bipolar disorder, had stayed home from school that day, and Oquendo wanted to make beef stew, one of his favorite meals. But, before she could start cooking, Tanner became extremely agitated. Not long afterward, she discovered that he had swallowed a handful of her anti-anxiety pills. She wanted to take him to the hospital, but first she called her sister, a former New York City police officer. Her sister told her to call 911. “I said, ‘I’m not calling the police, because I’m afraid they’re gonna shoot him,’ ” Oquendo recalled. “She told me, ‘Evie, don’t be ridiculous. They’ll know how to handle it.’ ”
