Nearly 160 Iowans were registered to run in Monday's Boston Marathon, where two bomb blasts killed three people and injured dozens more.
Three brothers from Cedar Falls ran in the race. Joey, Daniel, and David Sevcik are members of the Iowa State Running Club and according to Joey, they left the finish line area about 10 minutes before the explosions.
Sevcik said his group only heard one of the explosions and didn't know what was going on until they started receiving messages on their cell phones.
The explosions happened about three hours after the winners crossed the finished line. Des Moines attorney Doug Gross got a phone call from his daughter, shortly after the bomb blast, saying she was O.K.
Molly Gross was part of a group running to raise money for "Best Buddies," an organization that helps people with disabilities.
