CHARLOTTE, N.C.—Law enforcement officers with an arrest warrant demanded that a man come out of a house in North Carolina before four were killed by gunfire, the victims unable to survive shots coming from inside the dwelling, a witness and officials said Tuesday.
Still reeling from Monday’s attack—the deadliest against U.S. law enforcement officers since 2016—investigators in Charlotte said they weren’t sure whether there was a second shooter and that more work was needed to determine a precise timeline of events.
