Lindsay Parry, 35, lives in South Africa, works at Victoria University; visiting Boston with his wife and three friends for the marathon
Finished at 2:47, more than an hour before the attacks
He was 400 meters away from where the first explosion when off — at a pub with his three friends and wife in the Lennox Hotel on the first floor
“The cops and the police and the actual marshals of the race were incredibly efficient. They tore down all the barriers and ripped the advertising off the barriers to see if they could find any more explosions. Immediately, the medics started wheeling people off.
“When we left the hotel after 10 or 15 minutes, we walked out on the street to go back to our hotel [Liberty Hotel, a few blocks away], and there were people who weren’t even aware that the explosion had happened — people in restaurants, having coffee and laughing.”
“We saw people who were being wheeled out, but by that stage we hadn’t seen anybody lying or injured on the floor. I didn’t see anyone who I was certain was dead.”

Good afternoon, everybody. Earlier today I was briefed by my homeland security team on the events in Boston. We’re continuing to monitor and respond to the situation as it unfolds and I’ve directed the full resources of the Federal Government to help State and local authorities protect our people, increase security around the United States as necessary and investigate what happened.
The American people will say a prayer for Boston tonight and Michelle and I send our deepest thoughts and prayers to the families of the victims in the wake of this senseless loss. We don’t yet have all the answers but we do know that multiple people have been wounded, some gravely, in explosions at the Boston Marathon.
I’ve spoken to FBI director Mueller, and Secretary of Homeland Security Napolitano, and they’re mobilizing the appropriate resources to investigate and to respond. I’ve updated leaders of Congress in both parties, and we reaffirmed that on days like this, there are no Republicans or Democrats; we are Americans, united in concern for our fellow citizens.
I’ve also spoken with the Governor Patrick and mayor Menino and made it clear they have every single federal resource necessary to care for the victims and counsel the families and above all, I made clear to them that all Americans stand with the people of Boston. Boston police, fire fighters and first responders as well as the National Guard responded heroically and continue to do so as we speak. It’s a reminder that so many Americans serve and sacrifice on our behalf every single day without regard to their own safety, in dangerous and difficult circumstances and we salute all those who assisted in responding to quickly and professionally to this tragedy.
We still do not know who did this or why and people shouldn’t jump to conclusions before we have all the facts. But, make no mistake, we will get to the bottom of this and we will find out who did this, we will find out who did this, we will find out why they did this. Any responsible individuals, any responsible groups will feel the full weight of justice.
Today is a holiday in Massachusetts, Patriots Day, it’s a day that celebrates the free and fiercely independent spirit that this great American city of Boston has reflected from the earliest days of our nation and it’s a day that draws the world to Boston’s streets in a spirit of friendly competition.
Boston is a tough and resilient town, so are its people, I’m supremely confident that Bostonians will pull together, take care of each other and move forward as one proud city and as they do the American people will be with them every single step of the way. You should anticipate that as we get more information our teams will provide you briefings. We’re still in the investigation stage at this point but I just want to reiterate we will find out who did this and we will hold them accountable. Thank you very much.
