4 Poway Residents Registered for Boston Marathon; 2 Explosions Reported

There were reports of two bomb explosions Monday near the finish line of the Boston Marathon, a race with four registrants from Poway.

It's not yet clear whether all of the registrants from Poway were actually in the race and if they were injured during Monday's race.

In a statement on its Facebook page, The Boston Marathon said, "There were two bombs that exploded near the finish line in today's Boston Marathon. We are working with law enforcement to understand what exactly has happened."

Many media outlets have speculated on the cause of the explosions, but no official cause has been announced. Several gruesome photos from the scene of the explosion have been shared on Twitter from reporters and runners who said they were there, some appearing to show individuals missing limbs and blood splattered across the sidewalk.

According to the athlete tracker on the Boston Marathon website, four people registered for the race are from Poway. Three of the listed runners had half and finish times, but a fourth had no times at all.
