Tucsonan Shirley Reilly finished the Boston Marathon about an hour before the explosion. She was in her hotel room when she heard two explosions. She went to the window. “It was kind of crazy. There was a lot of smoke and I saw a lot of people running away from that smoke. It was kind of scary.” she said.

"I’m really sad. My thoughts and prayers go out to the people who have been injured or died," she said.
