SOMERVILLE, NJ - A man who is already in jail in connection with the murder of Carolyn Stone in the Bradley Gardens section of Bridgewater in 2009 was indicted Friday on charges of perjury and false swearing.

According to Somerset County Acting Prosecutor Michael H. Robertson, the indictment came from a grand jury against Gary Wilson, 33, concerning perjured testimony given at the trial of co-defendant David Granskie Jr. in September 2014.

Wilson is currently lodged in New Jersey State Prison.

Wilson is now being charged with three counts of perjury and two counts of false swearing.

According to Robertson, during Granskie's trial on charges of murder, aggravated sexual assault and conspiracy to commit both murder and sexual assault of Stone, Wilson was called as a witness for the defense. When under oath, Robertson said, Wilson testified that he saw Granskie go into the house and that he was not present for the murder and sexual assault that took place in the backyard.

In addition, Robertson said, Wilson said he had not observed co-defendant Rocky DiTaranto engage in sexual intercourse with the victim or choke her during sexual intercourse.

According to Robertson, these statement allegedly materially affected the outcome of the trial, in that they may have led the jury to reach a decision it might not have otherwise reached.

At the end of the trial, Robertson said, Granskie was acquitted of the murder counts that would have led to a sentence of life in prison without parole. He was also acquitted of knowing murder and aggravated manslaughter.

In addition, Robertson said, the jury could not reach a decision concerning the counts of felony murder, conspiracy to commit murder, conspiracy to commit sexual assault and reckless manslaughter.

The statements Wilson had made at trial, Robertson said, were counter to what he had previously said under oath and also contradicted statements made by Granskie later in his own guilty plea.

According to Robertson, during Wilson's guilty plea in July 2011, he said he had observed DiTaranto engaging in sexual intercourse with Stone in the backyard of the house and choking her while doing so. Wilson did not mention Granskie then, but Granskie pled guilty in November 2015, and acknowledged he had not gone inside the home, but had assisted in carrying the victim to the backyard where Wilson and DiTaranto planned to sexually assault her.

In addition, Robertson said, Granskie said that Wilson's statements at trial about his lack of involvement were not true.

Wilson was sentenced to 45 years in New Jersey State Prison, 85 percent to be served without parole, in July 2013 for the murder of Stone.
