The driver of a car Foster was found in is also being looked at by investigators, according to the station. He is no longer being held.
The victim, who has not been identified, was hit in the leg, police said, and was taken to a hospital in stable condition. Authorities think the shooter and victim were acquainted.
The event’s permit was for 200 people, but the crowd grew to thousands as word got out.

Many people at the event got into their vehicles and tried to drive away when the gunshots rang out, causing a traffic logjam, according to authorities. Some were injured in the scramble to leave.
“We had a number of police resources that were in the area already,” police Maj. Darin Schierbaum said, “and started mitigating traffic in park and on foot and in vehicles.”
