Two people were shot in the leg at Denver’s Civic Center during Saturday’s 4/20 pot rally and a third person was grazed by a bullet.
A man and a woman were both shot, said Denver Police spokesman Sonny Jackson. Their injuries are not life-threatening. A juvenile who was grazed by a bullet walked to a nearby hospital.
Both victims are in their 20s. They were taken to Denver Health Medical Center.
Police are looking for at least two suspects involved in the shooting. Investigators do not know what sparked the shooting.
