A general surgeon from Kansas says he was pressed into service helping the injured just moments after finishing the Boston Marathon.

Dr. Chris Rupe tells The Salina Journal he heard a loud explosion about 10 yards away after finishing his run Monday in a time of 4 hours, 4 minutes, 23 seconds. Rupe says he headed to what he thought was a building or grandstand collapsing, then heard the second blast.

He was directed to a medical tent where doctors usually help runners with problems like exhaustion.

Rupe spent about an hour inside, treating people mainly with injuries to their extremities. After that, Rupe says, most of the injured had been taken to hospitals.

Rupe’s wife _ pediatrician Abbey Rupe _ had finished the marathon well before
the explosions.
