AUBURN — A Utica man was sentenced on Thursday to 20 years to life in prison for robbing and assaulting a Sterling man in February 2017.

Derrick Sedore, 32, was convicted of nine felony charges in October for his crimes involving unlawfully entering a Sterling residence, injuring a man by striking his head with the butt of a loaded, operable rifle, and stealing property — including rifles and handguns.

Sedore didn't act alone, and the crime wasn't a first for him and his co-defendant, Caleb Pilkenton. The two were previously sentenced to seven years in prison for committing a 2011 burglary — previously described by prosecutors as "a bloody mess." At the time of the February 2017 crime, both were on parole after being released from custody less than four months earlier.

Sedore faced a maximum sentence of 25 years to life for convictions on six class B violent felonies including three counts of first-degree burglary, two counts of first-degree robbery, and one count of second-degree kidnapping. He was also found guilty of one count each of second-degree burglary, a class C violent felony, second-degree assault, a class D violent felony and fourth-degree grand larceny, a class E felony.

Sedore "shows no remorse for his actions" and "utterly refuses" to accept responsibility, Senior Assistant District Attorney Brittany L. Grome Antonacci said in Cayuga County Court Thursday as she asked Judge Thomas Leone to impose the maximum sentences for his crimes.

Joseph Sapio, Sedore's defense attorney, said Sedore asked him to request the court not to impose a life sentence. Sapio said Pilkenton, 27 at time of Sedore's conviction, committed the same crimes and received a 12-year prison sentence. He said the main differences were that Pilkenton pleaded guilty and accepted responsibility. Even if the court didn't believe Sedore was accepting one iota of responsibility, he said, he didn't believe it warranted being sentenced to an additional 13 years to life in prison.

"I'm sorry for what happened to (victim) ... I had nothing to do with it," Sedore said, claiming Pilkenton was the one that tied up and beat the victim. He claimed that Antonacci was making "false allegations" against him and "there's numerous things saying I'm innocent." One thing he pointed to was that his shirt color didn't match that of descriptions initially give at the time of the incident.

"He's not being punished for taking this case to trial," Antonacci said. She added that the victim testified Sedore struck him in the head with a firearm.

Antonacci said the lowest offers made available to Sedore prior to trial were 18 years or 20 years to life in prison, never 12 years. Leone noted Pilkenton faced fewer criminal charges and said he offered Sedore a 16-year prison sentence the day of the trial, but Sedore turned it down and walked into trial with "eyes wide open."

"The evidence against you is overwhelming," Leone said. He added that 12 jury members "didn't believe a word you said."

For his six class B felonies, Leone sentenced Sedore to 20 years to life in prison. Sedore was additionally sentenced to 16 years to life for his class C felony, 12 years to life for his class D felony and 15 years to life for his class E felony.

Sedore indicated that he plans to appeal the sentence and has already retained an appeal attorney.
