Multiple shooters opened fire at a crowded block party in south Baltimore early Sunday, killing two people, wounding 28 more and fueling an intense manhunt for the killers and a call for an end to violence in the city and across the nation.

Acting Police Commissioner Richard Worley said a 20-year-old man and an 18-year-old woman were killed and at least two survivors were in critical condition. Seven others also remained hospitalized late Sunday.

The victims ranged in age from 13 to 32; four of them were under 18, Worley said. Officers were studying video and interviewing witnesses to try to identify suspects. Worley said the block party organizers had not obtained a city permit so details of the party were not immediately known. He described he crime scene as “huge” and said several blocks remained cordoned off more than 15 hours after gunfire rocked the neighborhood shortly after 12:30 a.m.

“We know there were at least two shooters,” Worley said. “We don’t know if they were targeting or just shooting indiscriminately down the street.”

Mayor Brandon Scott said “every single city agency” will help the neighborhood in its recovery. He urged anyone with information on the killers to come forward.

“This was reckless, cowardly act that happened here that has permanently altered many lives,” Scott said “I want those responsible to hear me, hear me very clearly − we will not stop until we find you. And we will find you.”

Baltimore homicides were trending lower this year

Just three days ago, Maryland federal prosecutor Erek Barron announced that, because of the crime reduction efforts led by his office, homicides and non-fatal shootings in Baltimore were continuing to “trend down significantly.”  For the first half of 2023, homicides were down 22.2% and non-fatal shootings down 12.6%.
