34 year old Horton was found guilty of 9 counts by the jury, the most serious of which was aggravated murder.
That carries a mandatory sentence of life in prison, without parole.
Throughout the case, Horton's Attorney Richard Rich never denied the fact that Horton robbed the Chemung Canal Trust bank in Big Flats, or that he killed New York State Trooper Andrew Sperr.
But, Rich always contended that Horton never intended to kill Sperr.
Chemung County District attorney John Trice said in his closing arguments, the fact that Horton shot Sperr 6 times proved he intended to kill him.
During deliberations, the Jury did return to the courtroom with two questions, defining aggravated murder, and the difference between 1st and second degree murder.
It took them only 2 and a half hours to convict him on all 9 counts.
Horton will be sentenced on October 19th.
