根据短文内容回答问题。
Red Ribbon Week is held every year, usually during the last week of October. It started with a police officer named “Kiki” Camarena. He was sent to Mexico in order to investigate(调查) a Mexican drug company and stayed there for four and a half years. His efforts helped put a stop to several major drug making companies. So the bosses wanted to murder the men who brought them down. When Camarena left his office for a lunch date with his wife on February 7, 1985, a car drove up and kidnapped(绑架) him, and a month later he was killed. At that time he was only 37 years old.
Shortly after his death, people in Camarena’s town began wearing red ribbons in his honor. Then Camarena’s high school friend, Henry Lozano, started Camarena Club. Hundreds of people joined the club and promised to be drug-free in order to honor the death of Camarena. And then schools in several states began to join in. Now, at the end of every October, millions of Americans wear red ribbons in memory of “Kiki” Camarena. So, in 1988, the first national Red Ribbon Week was founded in America.
Red Ribbon Week has become the largest drug education and prevention organization in the United States. It encourages communities to stand up against drugs and it encourages children to make a promise not to take drugs in their life.
