Three people were fatally shot at homeless encampments in Minneapolis over the weekend and three others were injured, Minneapolis police said.

On Sunday afternoon, two men were killed and a woman was wounded in a shooting at a camp on the 4400 block of Snelling and Hiawatha avenues, according to a news release from the Minnesota State Police Department.

A man was fatally shot and two men were wounded early Saturday morning at a camp near E. 21st Street and 15th Avenue S., Minneapolis Police Chief Brian O’Hara said.

According to the release, at approximately 2:21 p.m. Sunday, officers from the 3rd Precinct who responded to a shooting at the small camp near Hiawatha Avenue located two men and a woman suffering from gunshot wounds. The two men died at the scene. The Hennepin County Coroner’s Office will identify the victims.

Three adult males were initially detained but were freed and released. According to the statement, police have not ruled out the possibility that the Sunday afternoon and Saturday morning shootings are related.

O’Hara provided the following details about Saturday’s shooting, which happened about 3 1/2 miles north of Sunday’s episode:

Shortly before 5 a.m., officers were called to the homeless camp on reports of a shooting. Officers discovered three men had been shot. One man was “lifeless,” O’Hara said. Officers performed CPR on all three men until they were taken to the hospital, he said.

A man died. The other two were in critical condition with life-threatening injuries, he said.

Early information indicates that between 4:30 and 4:45 a.m. three people approached the camp and the shooting occurred, O’Hara said. He noted that one of the victims had a small BB gun that looked like a real gun, but investigators aren’t sure what role it played in the shooting.

O’Hara confirmed that a 911 caller reported sounds of automatic gunfire at the scene of the shooting.

He said the encampment is an ongoing problem for neighborhood residents and was formed after a much larger encampment near Franklin Avenue near the underpass was dismantled.

“There is something about these camps that causes crime around them,” he said. “That’s just what the data shows.”

O’Hara said 13 percent of all murders in the 3rd Precinct occur within 500 feet of an encampment and 19 percent of all gun violence occurs within 500 feet of one.

“We know that 23 percent of this year’s shooting victims were within 500 meters of a camp,” he said, later adding that camps are not “humane” places for people.

Last month, two men were killed in shootings at the camps.
