This year's service to honor EMS personnel killed in the line of duty will remember 73 heroes -- the largest ever.

Services are set for 6 p.m. Saturday, May 24 at the First Baptist Church in Roanoke, Va.

"In addition to those who died in 2007, we are honoring people who died in incidents in previous years," said Kevin Dillard, president of the National EMS Memorial Service. NEMSMS previously waited for notifications of EMS line of duty deaths from the agencies of fallen responders. However, this year NEMSMS staff went back and researched these deaths to find those that were not reported.

The weekend events begin Friday evening when bicyclists from the National EMS Memorial Bike Ride are welcomed by family and friends of the fallen heroes. Police officers escort the group through the streets of Roanoke where they receive waves and applause.

The riders begin in Kentucky and New York City six days earlier and ride an average of 75 miles each day to arrive in Roanoke for the memorial service.
