WASHINGTON - JUNE 26: Archbishop Donald Wuerl, Catholic Archbishop of Washington, greets and thanks people who attended an interfaith prayer service to honor those who died in a Metro train collision earlier in the week at Old St. Mary's Catholic Church June 26, 2009 in Washington, DC. The firefighters who attended the religious service were the first-responders to the accident, which left nine people dead and is the worst in the mass-transit system's 33-year history.
