STRUTHERS — A 17-year-old is in custody, the second person accused in the Sept. 21 shooting death of 4-year-old Rowan Sweeney.

Members of the Northern Ohio Violent Fugitive Task Force on Wednesday arrested the teen after finding him in Youngstown.

He attempted to flee from a home in the 100 block of South Pearl Street but was apprehended, the U.S. Marshals Service said in a news release. Three firearms and ammunition were taken out of the home.

The name of the teen was not released by the marshals service or others close to the case.

Michael Yacovone, Mahoning County assistant prosecutor, said Thursday that charges the 17-year-old will face could lead to him being tried as an adult.

The matter remains under investigation, Yacovone said, though the case is pending in county juvenile court.

David Sweeney, Rowan’s father, on Thursday expressed his gratitude to investigators.

“Nothing can describe how I feel. I’m so thankful for our law enforcement. Their dedication to this case will ensure justice is served for Rowan,” he said.

This arrest is the latest development in the ongoing investigation.

Kimonie Bryant, 24, has been held in the Mahoning County jail on aggravated murder, accused of killing Rowan in the early morning shooting.

Bryant also is accused of shooting four adults who were in the home at the time: Andre McCoy, Yarnell Green Jr., Sweeney’s mother Alexis Schneider and Cassandra Marsicola.

Mahoning County Prosecutor Paul Gains previously suggested a large amount of money was a reason behind the shootings. Green, a self-employed barber, had recently received federal pandemic unemployment assistance. About $5,000 in cash remained from the check and was on a coffee table.

In the moments after the shooting when the gunman fled, the cash was gone.

Later on Sept. 21, Bryant was taken into police custody.

The child was asleep when the gunman entered the home around 2 a.m. at 111 Perry St.

Schneider covered Rowan, begging the gunman not to shoot the boy, authorities have said.

Bryant was indicted on aggravated murder with death penalty specifications last month, making it the first time in four years that someone has been indicted on death-penalty level charges in Mahoning County.

He also is indicted on four counts of attempted murder and four counts of felonious assault, as well as aggravated burglary and aggravated robbery charges.
