Sioux Falls Police say the driver of a Jeep Wrangler hit the motorcycle and the two people on it.
The accident happened at 26th Street and Grange Avenue in Sioux Falls, which is fairly close to the University of Sioux Falls.
It happened just after midnight and that's where people gathered, Saturday at dusk.
Friends and family have started a small memorial at the corner.
Many were seen holding candles, sharing hugs, laying down roses and saying a few prayers.
Sioux Falls Police aren't confirming the names of those involved but will only say they are both in serious condition.
People at this vigil told us someone did die, making it a sad night for friends, family and those who ride motorcycles.
One close friend to the victims say they were just riding and having fun.
"We were out riding around with friends of ours, clean, no one was drinking, we were having a good time. She gets hit by someone who was being stupid, absolutely stupid and not using their head," Andrea Osthus said.
"It's difficult, as a pastor and a friend, it's extremely difficult but sometimes out of the bad comes the good. It brings close family and the community together," Terry Barton said.
Here's a little more information about the crash:
Police tell us the bike slowed down at a traffic light and that's when the jeep hit the back of it, the bike was dragged for one block.
Police say the driver of the Jeep took off running and police say that person had been drinking.
The driver was found at a nearby home.
The driver of the Jeep is facing new charges, Saturday, including a second DWI, having no insurance and a hit-and-run.
