A Bakersfield city firefighter and his wife, an E.R. nurse at San Joaquin Hospital, were both at the Boston Marathon.
They say after the explosions, they raced into action, looking for people to help.
This is the second year Dennis and Hope Roe attended the marathon.
Dennis says soon after his wife crossed the finish line, they heard the explosions.
"Saw a big puff of smoke, explosion pretty much immediately and everybody looked hard toward the explosion and everybody was going, what was that, what was that," said Dennis Roe. "And then the next explosion happened a few minutes later, the second explosion didn't seem quite as loud and I figured wow, that sounded like a bomb because I don't know what else it could have been because those are pretty decent explosions -- huge columns of smoke came rising up."
Both have attended many marathons throughout the years.
Dennis says he took a picture after Hope finished the race, minutes before the first explosion.
"I could see construction in front of me so my first thought was something fell, something dropped, something is going on there," said Hope Roe." Then the other one went off and I heard someone ask someone else, is that normal? And the person goes, no. So we're all kind of walking around and there's kind of a surreal feeling and I was a block behind it so I didn't see it, didn't see any people. There was a lot fewer people where I was, but you can feel the tension in the air."
Both say their medical backgrounds prompted them to spring into action and look for people to help.
They say they were directed to several medical tents near the finish line.
"Few emergency vehicles passed by, finally a couple of firemen came by -- they were looking ready to go to battle, said Dennis Roe. "They had their gear on and I asked them if they would like some help, I was firefighter and my wife is a ER nurse and they said we have people coming from all directions, we're good right now."
But the Roe's say they still looked for people to help before they were told to evacuate.
"The main issue is they were trying to get everyone out because they didn't know the full implications how many other sites there might have been," Hope Roe added.
Dennis Roe says the FBI has asked for several videos he took minutes before the explosions.
The Roe's are scheduled to fly home Saturday.
