Gunfire erupted at a block party in Baltimore on Sunday — killing two people, wounding 28 and leaving an extensive crime scene that marred the U.S. holiday weekend, police said. Three of the wounded were in critical condition and more than a dozen were under 18. The shooting took place just after 12:30 a.m. when at least two people opened fire at a block party in the Brooklyn Homes area in the southern part of the city, said Richard Worley, Baltimore's acting police commissioner. No arrests had been made by late afternoon. It wasn't clear if the shooting was targeted or random, Worley said. The shooting comes amid gatherings around the country leading up to the July Fourth holiday. Elsewhere, a shooting in Kansas left seven people with gunshot wounds and two more victims hospitalized after being trampled as people rushed out of a nightclub early Sunday morning, police there said.
