McKelvey is charged in the deadly shooting on Adair Avenue that killing Corey Owens in April of 2014.
Owens would die from a single gunshot wound to the back of his head, fracturing his skull, and injuring his brain.
The jury found McKelvey guilty of malice murder, felony murder, aggravated assault, and possession of a firearm during the commission of a crime Friday afternoon.
"They have been waiting three years for justice for Corey Owens, so I'm happy we could deliver that to them, so they can go home, and get some closure," said Lead Prosecutor, Chris Williams following the verdict.
A cold-blooded, pre-meditated murder is what the state was attempting to prove of 25-year-old Sacorey McKelvey.
"He knew that he was going to ambush Corey Owens. He knew that he was going to get his idea of revenge. Corey Owens did not know Sacorey McKelvey planned to ambush him at the bottom of that hill," said Don Kelly, during closing arguments.
Throughout the course of the trial, the defense team for McKelvey working to establish lack of proof and credibility in witness testimony.
"The timing here is critical. There is absolutely no evidence, no testimony that Sacorey McKelvey has any way of knowing that Corey Owens would be coming down that hill at that point. No evidence at all," said Defense attorney for McKelvey, Susan Henderson.
Jurors ultimately deciding in the State's favor.
"We are just pleased that justice was done for Corey Owens, and Mr. McKelvey was held accountable for what he did. Senseless killing," said Williams.
McKelvey faces the minimum of life without the possibility of parole. Judge Mcbride, who is presiding over this case set a sentencing date for September 5, at 9 a.m.
