On Sept. 28, 2017, Christopher Grover was found dead from a gunshot wound in the Town of Poughkeepsie home he shared with Nicole Addimando, a 2007 FDR graduate.

At the time of his murder, Grover was the head coach at Mr. Todd’s Gymnastics in Poughkeepsie. According to his obituary, Grover graduated from Red Hook High School in 2006. He previously coached gymnastics at Fly High Gymnastics in Red Hook.

Investigators began what was described as a "painstaking six-month investigation"  involving phone records, internet searches, computer forensics, dozens of interviews, and more to determine there were inconsistencies in Addimando's alleged history of abuse and her claims of self-defense. There was also overwhelming evidence the murder was intentional, officials say.

Evidence at the trial proved Grover was killed by a point-blank shot to his head while he was sleeping on his couch, officials say.

In April 2018, a Dutchess County jury found Addimando guilty of murder after three days of deliberation.

“The defendant’s allegations of abuse and self-defense were exhaustively investigated for two years by many detectives and law enforcement agencies.” Putnam County District Attorney Robert Tendy said. “We took the defendant’s claims of abuse very seriously. In the end, everything pointed to the fact that Christopher Grover was asleep when the defendant executed him, and there was no evidence that he had ever abused her. In fact, there was evidence that she was extremely verbally abusive to him and planned the murder in advance. Fortunately, she didn’t get away with it. The jury reviewed the extensive forensic evidence and trial testimony and unanimously rejected the defendant’s claims.”

The Putnam District Attorney’s office was named a special prosecutor on the case due to a conflict with the Dutchess County District Attorney’s office.

In February 2020, Addimando was sentenced to 19-years to life in prison.

Addimando is scheduled to appear in court on Thursday to appeal her sentence. Oral arguments are expected to start around 10 a.m.

"The arguments will center around whether Nikki’s constitutional rights were violated during her prosecution and trial," the We Stand With Nikki Facebook page states. "The decision could take a month, a year, or maybe even longer. It’s statistically rare for appeals to be successful, however her legal team is confident in their arguments."
