An upstate New York man will likely spend the rest of his life behind bars after being convicted of an octogenarian's brutal murder.

Jonathan E. Melendez, 40, was convicted by a jury of his peers in Jefferson County for the murder of Rena L. Eves, 88, on Thursday – with the triers of fact rendering guilty verdicts on all counts against the self-represented defendant.

"I didn't kill Rena," Melendez said when taking the stand in his own defense on Monday, according to a courtroom report by NNY360 .

But when it was all said and done, jurors simply did not agree.

In sum, the defendant was convicted on one count each of murder in the second degree , assault in the first degree, criminal possession of a weapon in the third degree, and tampering with physical evidence.
