CLEVELAND (WJW) — Less than three hours after local and federal authorities asked for the public’s help in finding a 17-year-old boy they said is a “danger to the public,” the suspect turned himself in.

Antonio Baker, 17, was wanted on charges of aggravated robbery and for multiple shootings, including a murder at Arbor Park Village apartments on Sept. 20, said Cuyahoga County Prosecutor Michael O’Malley and U.S. Marshal Pete Elliott at a Thursday afternoon media briefing.

He turned himself in Thursday afternoon to U.S. Marshals and Cleveland police at the city’s 3rd District station, according to a Thursday update from the prosecutor’s office.

In the span of five weeks, Baker shot three people, O’Malley said during the earlier media briefing.

Authorities showed video of the Sept. 20 shooting, showing the 22-year-old victim riding away on a bicycle. The suspects fired 27 shots, including with an assault weapon, O’Malley said. The victim tried to run, but died there, he said.

“We need the public’s cooperation and we need to locate him or it is very likely there will be more people in the city of Cleveland who lose their lives, or Mr. Baker may lose his life,” said O’Malley.

Authorities believed Baker was in the area of Arbor Park, where the Sept. 20 shooting happened. Elliott urged Baker to turn himself in.

Anyone with information on Baker’s whereabouts was urged to call 911 or the Marshals’ hotline at 1-866-4-WANTED (866-492-6833). Reward money was available for “the right tip,” Elliott said.

The suspects in the Sept. 20 shooting are believed to be 17-year-old Baker, 18-year-old Bryce Tanksley and a 15-year-old.

U.S. Marshals tried to apprehend Baker on Monday, when he arrived with two friends at a local hospital after they had reportedly been shot on St. Clair Ave.

He fled when he spotted police, O’Malley said. Marshals then canvassed the area for the next two days, at the county’s request.

Then on Wednesday night, the 15-year-old was killed at King Kennedy North High Rise along East 59th Street, O’Malley said. The investigation into the teen’s death continues, he said.

“What it did was highlight the fact that we need to get Antonio Baker off the street before he is either shot or kills somebody,” O’Malley said.

U.S. Marshals arrested Tanksley Thursday morning on an aggravated murder charge along Lundy Avenue in Cleveland, Elliott said.

Baker is also believed to have been the shooter in two attempted murders in August, one along East 49th Street and another along Woodland Avenue. Each of the victims was shot multiple times, O’Malley said.

“This senseless violence continues to escalate. The proliferation of guns, the availability of guns, the comfort that juveniles have when using weapons continues to plague our community,” O’Malley said.

“Juveniles with guns are far more dangerous than adults with guns.”

There have been a record-breaking number of juveniles charged this year with homicides, O’Malley said. There have been 36 juveniles charged in the first nine months of the year, compared to 35 for all of 2021.

“As far as the retaliation, we see it far too often in our community. … Too often we are seeing one senseless homicide lead into another senseless homicide in the name of retaliation,” O’Malley said. “Let the justice system do its job and try to hold people accountable because answering guns with guns is never the solution.”
