Shootings erupted across the country, in both rural and urban locations, during a holiday weekend commemorating the end of slavery after the Civil War.
In Milwaukee, gunfire after a Juneteenth celebration left six people injured, including the suspected gunman, authorities said Monday.
The wounded were between the ages of 14 and 19 and included four females and two males, Milwaukee Police Chief Jeffrey Norman said during a news conference.
He described their injuries as non-life threatening. The shooter is believed to be a 17-year-old male, Norman said.
Neither the victims nor the suspected gunman were identified and a possible motive remained unclear. It also wasn't clear how the 17-year-old was injured.
During the news conference, Milwaukee Mayor Cavalier Johnson described the holiday event as "glorious" but pleaded for people with guns to stay away.
"There were families out here," he said. "There were kids out here. There were babies out here."
"You don't have the right to steal the joy this community felt today," he said.
More than 1,600 miles away, in the small northern Idaho town of Kellogg, four people were found dead Sunday night after their neighbor allegedly gunned them down, Idaho State Police said.
The suspected shooter was identified only as a 31-year-old man, the agency said in a statement Monday.
He was booked into Shoshone County Jail on suspicion of murder, the agency said, adding that it would not provide details about a possible motive or the suspected gunman's relationship to the victims until after a first court appearance.
In Chicago, five people were injured in a shooting on the city's far South Side, police said. The precise time of the attack was not clear, but police started tweeting about it at 7:24 p.m. The conditions of the injured were not available.
Police in Washington, D.C., reported that four people were struck in two shootings Sunday night. The first happened about 8:45 p.m., police said, and the victims, 15 and 18, died at the hospital.
A little more than an hour later, two more people were struck by gunfire, Washington police said, with one of the victims, a 6-year-old boy, hospitalized in critical but stable condition. The other victim, an adult, is stable, police said.
In San Francisco, two people were injured Sunday evening in a shooting near Fisherman's Wharf and the Embarcadero, two of the city's most popular attractions for visitors, police said.
The victims' conditions were unavailable. The attack may have involved two vehicles, police said in a statement.
Officers responding to a 6:48 p.m. report of a shooting near the wharf found both victims and rendered aid, police said in the statement. The injured were rushed to medical facilities, police said.
"At the scene officers learned that there were possibly two vehicles involved in the shooting," the police department said.
No other suspect information was available.
Sunday's violence followed a night of mass shootings Saturday, when at least four people were killed and more than two dozen others were injured in Illinois, Washington state, North Carolina and St. Louis.
In the St. Louis shooting, gunfire struck 11 people ages 15 to 19 at a party around 1 a.m. Sunday.
One of the victims died, police said. A 12th person was hurt while getting trampled by people trying to flee the scene. A 17-year-old suspect has been arrested, police said.
In the Illinois shooting, one person died and 22 others were hurt when gunfire erupted after midnight Sunday at a Juneteenth celebration in Willowbrook, a suburb of Chicago, authorities said.
Meanwhile, a Juneteenth celebration in Asheville, North Carolina, ended with a shooting late Saturday that injured two juveniles, police said. A suspect, 16, was charged, police said.
As of midday Monday, the Gun Violence Archive had documented 112 deaths and 73 injuries since Saturday.
With several hours to go in the long weekend and data from shootings still to be reported, it was not yet clear how the scope of gun violence over the three days will compare with past year's. Over the three-day Juneteenth holiday weekend last year, 181 people were shot to death and 438 were injured by gunfire, according to the archive. During the three-day Memorial Day weekend, 180 people were shot to death and 464 were injured.
