A 34-year-old man was arrested Thursday on allegations that he was a perpetrator in a shooting Tuesday in Minneapolis shortly before midnight that left three people dead and two wounded.
The shooting was the first of three on the city‘s South Side within 20 hours that left a total of five people dead.
During a media briefing late Thursday afternoon, Minneapolis Police Chief Brian O‘Hara said James Duane Ortley, recently of Minneapolis, is believed to be responsible for the mass shooting, but the chief added that others may have been involved. O‘Hara said arrests have yet to be made in the two other fatal shootings that quickly followed.

The U.S. Marshals Service said Ortley was arrested about 3:30 p.m. in the 1600 block of S. 4th Street on a warrant alleging multiple counts of second-degree murder. There is also a federal warrant for his arrest tied to a felon in possession a gun allegation.
“This is a significant step forward in what has been an intense and fast-moving investigation into the most violent incident the city has suffered this year,” O‘Hara said.
Murder charges filed against Ortley in Hennepin County District Court remained under seal and out of public view as of late Thursday afternoon. Ortley’s criminal history in Minnesota includes one conviction each for first-degree robbery, second-degree assault, illegal weapons possession and fleeing police.
Earlier Thursday, police said they were joining with other law enforcement agencies and activating “every available resource” toward finding those responsible for the outburst of shootings.
The last of the killings from three shooting incidents occurred about 7:45 p.m. Wednesday on 15th Avenue S. near E. Lake Street, where officers found a man in his 50s with critical gunshot wounds. Emergency medical responders took him to HCMC, where he died, police said.
