New Canaan's David Keeffe was on the subway, one stop away from the finish line of the Boston Marathon when two explosions went off.

"We didn't hear anything, but they shut everything down and sent everyone out into streets, which was chaos," Keeffe said in an interview Monday afternoon. Keeffe had finished running the marathon 10 to 15 minutes before the explosions. "I was on the corner of Massachusetts Avenue and Commonwealth Avenue, very near Boylston [Street]. Police were directing us to going any way but that."

Two bombs exploded near the crowded finish line of the Boston Marathon on Monday, killing two people and injuring more than 50 others in a terrifying scene of broken glass, smoke and severed limbs, authorities said. Keeffe said public transportation was shut down, there was no cell service, and police and ambulances were rushing to the area.

"It was like New York City after 9/11," he said.

Keeffe said he was picked up by a man leaving the Red Sox's Patriots Day game, the annual civic celebration of the battles of Lexington and Concord. The man saw Keeffe standing in his running clothes and drove him more than 10 miles to his car.
