Responding to a flurry of 911 calls about shots fired, officers arrived just after 12:15 a.m. Sunday at Seventh Street Truck Park, a bar on a busy dining stretch near downtown St. Paul, where they found more than a dozen gunshot victims. Law enforcement officials worked with “good Samaritans” to help render aid to prepare the victims for transport, St. Paul police said in a news briefing early Sunday.
