Thousands of people were at Civic Center Park in Denver for a 420 rally Saturday when suddenly shots rang out at 5:02 p.m.
Police said the primary suspect in the shooting was described as a black male with a light complexion, 6 foot tall, 180 lbs., wearing a gray hoodie, black pants and a Carolina blue baseball cap. Photography student Alexander Pringle told 7NEWS he saw the shooter open fire and managed to snap a photo of the shooter running away. (See that photo above, click on the number 2.)
A man and woman, between 20 and 30 years old, were shot in the leg, Denver police said. Their injuries were considered non-life-threatening.
A third victim, a juvenile, was grazed by a bullet and walked into a nearby hospital, police tweeted.
On Sunday, Denver police said they turned the shooting investigation case over to the Gang Unit.
Miguel Lopez, who organizes the 4/20 rally, told 7NEWS in the 29 years the rally has been held in Denver this is the first time there's been a shooting.
