LOUISVILLE, Ky. (WDRB) --It's almost been two weeks since this scene on River Road shocked witnesses, the EMS Community, and the victim's families.

"Oh my gosh, it was heartbreaking, absolutely heartbreaking," co-worker, Major Mary Taylor said.

John Morgan and Jon Johnson were working to get to a call, like they had done several times before, when they collided with a blue car, killing the driver. They were alive, but badly hurt.

"He had a tibia plateau fracture, and a sternum fracture," Johnson's fiance,Tammy Hall, said.

One of the very ambulances they work out of had to rush them to a hospital, where they've been since.

"One of the individuals needed up to 30 units of blood. That's three times what the body normally has in it," said Anchorage Fire Chief Bill Rockwood.

"It could've been far more tragic if when they showed up to the hospital, that the blood wasn't there to save lives," Lindsay English from the American Red Cross explained.

The blood given after that terrible crash was from a donor, and you can give the same kind of gift next weekend at Churchill Downs. It's called the Holiday Hero Independence Day Blood Drive.

"It's really to shore up the supply, and prevent a shortage as we head through the summer months," English said.

Each person that walks in the door could very well save the next person in need, just like someone did for one of the EMTs.

"We're used to being the ones who actually save people and assist people in the community, and it's good that people are also there for us," Taylor said.

When you show up to Churchill to give, you'll get one free admission pass to King's Island and some ice cream.

It's happening from July 8-10, beginning at 12 p.m. and ending at 7 p.m.

Organizers ask that you make an appointment. You can do that by calling 1-800-RED-CROSS.
