DENVER - The investigation into the shootings during Saturday's 4/20 rally is being turned over to the Denver Police Department's Gang Unit, according to a tweet the department posted Sunday.

Investigators have talked to several witnesses but are asking anyone with video footage of the event to come forward, according to another tweet from Denver police Sunday.

Police are searching for the two men who fired shots during the rally in Civic Center Park, injuring three people and causing thousands of people to run away from the area.

"Does the behavior of the participants in these events reflect well on our state?" asked the head of Smart Colorado, Henny Lasley.
