A sports vehicle driver plowed into a crowd of spectators at a Boise, Idaho, auto show, injuring at least eleven, authorities say.
On Saturday, a group of automotive enthusiasts hosted this season's, but final "Cars and Coffee" event.
Authorities said an investigation is underway and the evidence will be sent to the prosecutor for "possible charges".
Six of the injured were transported to the hospital via ambulance, while five went by private vehicles.

Boise Police say that while the examination is continuous, preparatory data demonstrates that the driver of the Porsche was quickening quickly as he cleared out the auto indicate onto eastward Overland Road, lost control, and kept running into the group.
The driver was on scene cooperating with police.
Eastbound Overland Road remains closed from Entertainment Way to Cole Road.
"We do not have any information that this was an intentional act", Lebar said. He lost control and drove into the crowd. "And after that it was sheer screaming".
Lt. Lebar said "excessive acceleration" is to blame for what happened. This can be confirmed in a video sent to the local news where the vehicle succumbs to oversteer and the driver fails to correct the action.
The event has occurred each month since 2013, according to the Facebook profile. Check back for updates as they are confirmed.More news: Liverpool Drop Points in Frustrating Home Draw Despite Dominance over Burnley
