YOUNGSTOWN — Antonio E. Davis, who was 17 at the time he was indicted in the shooting death of a Farrell, Pa., boy who came to Youngstown to sell two iPhones, got 11 years in prison Wednesday.

Davis, 20, will serve less than nine years because he received credit for about 2 1/2 years in the Mahoning County jail awaiting trial. Davis pleaded guilty in October to a reduced charge of involuntary manslaughter and two counts of aggravated robbery, plus three gun specifications in the death of Damon Marinoff, 15. Judge Anthony Donofrio of Mahoning County Common Pleas Court handed down the sentence.

Davis used an Alford plea, which means he pleaded neither guilty nor innocent but “accepts the ramifications of a guilty verdict … without first attesting to having committed the crime,” according to the Legal Information Institute on the internet, which is a project of the Cornell Law School.

Prosecutors said Davis was with another person who fired the fatal shots, but Davis was indicted on aggravated murder and murder and aggravated robbery for participating in the crimes.

Marty Hume, county assistant prosecutor, said Marinoff intended to sell two iPhones on the Letgo computer app for $275 and met the “buyer” at 722 Sherwood Ave., with his sister’s boyfriend driving him there.

When they got there, Davis stood at the driver’s side window with a gun and robbed the driver of his wallet and money, Hume said. Davis was 16.

“On the passenger side, a co-conspirator and person Mr. Davis was aiding and abetting in commission of a robbery” got into a conflict with Marinoff, leading the other person to shoot Marinoff, killing him, Hume said during an earlier hearing. No charges were ever filed against the second person.

Donofrio also ordered Davis to make restitution to Marinoff’s family of $4,350 for funeral expenses.

During the hearing, Davis read a statement, saying he knows what it feels like to lose someone.

“Earlier this year I lost my baby sister of 10 years of age. I think about it every day. So I know how it feels,” Davis said. He was referring to Persayus Davis May, 10, who was shot to death Aug. 18 while inside her family’s home on Samuel Avenue on the South Side. The shooting took place at 2:27 a.m. and also injured three adults who were outside of the home.

No arrests have been made in the case.

Donofrio said he knows that Davis is “a very young man,” but he “started out his life the wrong way.” He said if Davis got 11 years in prison, he could still “turn his life around” when he gets out.

The judge mentioned that Davis committed another crime that caused him to be incarcerated for several years that involved similar circumstances as those in the Marinoff killing. That crime involved the robbery of a pizza delivery person, the judge said.
