COLLEGE STATION, Tx (KYLE) — More than four hours into one of the most prestigious marathons tragedy struck as two bombs placed about 100 yards apart detonated within 12 seconds of each other.
More than 170 were injured and three were killed.
Now thousands of Americans are trying to understand why and Texas A&M senior Zach Ginnings is one of them.
"As far as processing it goes, I mean it's still an on-going thing," said Ginnings. "I'm just trying to wrap my head around what happened not really knowing the ramifications of what that might mean."
Monday was Ginnings second time running the Boston Marathon. He finished the race about 40 minutes before the explosions and was in his hotel room when he heard the devastating news.
"I had like 20 texts and everyone was asking if I was ok. I didn't know what was going on so I was like, 'Yeah I mean I ran the race.' And then one person said something about an explosion and I was like, 'What?' so I turned on the TV and that's when I saw what was going on."
Along with Ginnings, six other runners from Bryan-College Station also ran in the race and are all believed to be ok.
Ginnings says he's grateful to be alive, "I keep seeing the video they show over and over again from the finish line of that man falling down from the explosion, I mean my feet literally ran right where he did and those [bombs] could have gone off when I went through."
