South Floridians who returned from Boston after attending the marathon described the chaos when two bombs exploded at the finish line.
John Carlin works between Miami and his hometown of Boston. He attended the marathon Monday to cheer on a friend who was running, and arrived at Miami International Airport Tuesday morning.
SPECIAL SECTION: Boston Marathon bombings
"We were just watching our friend compete," he said. "We heard two blasts within about 10 seconds of each other. People running, flashing lights -- we knew something was wrong."
Carlin said he was about one block from the blast site and didn't know where his friend was.
"We were worried about our friend because he was in that area," said Carlin. "Luckily, he had finished and decided to go home, so we all met him at home and it ended up being a happy reunion."
"It was very upsetting," said a woman who was vacationing in Boston and arrived in Miami Tuesday.
"We just have to keep going through our daily routines and hope for the best," added Carlin.
