Investigator Jack Frost, now with the Liberty County, Georgia, district attorney’s office, was among the first detectives called to a south Georgia swamp on Dec. 2, 2022, after hunters discovered a female torso in a ditch. Detectives recovered a Milwaukee-brand knife, a plastic storage tote with what appeared to be blood, and wipes. Frost later found the rest of the body five days after the initial discovery. Authorities said the woman had defensive wounds; assistant district attorney Laurie Baio said, “There’s no one that winds up dismembered in the woods that’s not a — a victim of homicide.”
The Georgia Bureau of Investigation released forensic sketches to help identify the woman. The sketches generated hundreds of tips. One came from Heather Thomas, 500 miles away in Virginia, who recognized the image and believed it looked like Mindi Kassotis. Heather knew Mindi because Mindi had married Heather’s ex-husband, former Naval JAG officer Nick Kassotis.
Nick had served globally — in Iraq, Italy and at the Pentagon — and worked on sensitive cases. He and Heather divorced in 2015; that same year Nick began dating Mindi, a legal secretary in Washington, D.C. They married in 2016. Friends described Mindi as romantic and enthusiastic about starting a family; she produced a podcast called “Compelling Women.”
Over time, Mindi’s life grew strange. She and Nick moved often, living in three states. Mindi increasingly communicated with friends only via the encrypted app Signal, reportedly at Nick’s suggestion. She told friends they had been hacked, their bank accounts frozen, and that they were being surveilled — allegedly due to Nick’s classified work. Friends said Mindi grew terrified, rarely leaving the house, and believed an undercover team disguised as tree surgeons had installed surveillance cameras around their home.
Heather Thomas had been trying to track Nick for nearly two years after their divorce, partly because he owed her $1.5 million under a court judgment. Using connections, she followed his movements and suspected he was in the Southeast. In late 2022, while Heather was still tracing him, Nick and Mindi were hiding in Savannah. That summer Mindi told friends she was pregnant.
After Thanksgiving 2022, friends say Nick called to tell them Mindi was gone, saying she had died from a sudden medical problem and been cremated without a funeral. Heather and Mindi’s parents received conflicting messages, including an email falsely claiming Nick had died in a car crash. Heather grew suspicious and contacted Georgia authorities after seeing the forensic sketch; DNA and genetic genealogy confirmed the swamp victim was Mindi Kassotis.
Investigators could not find any evidence Nick had died. Instead, they found a new identity and a driver’s license: Nicholas Kilian James Stark. He had been living in Lancaster, Pennsylvania, with a third wife, Samantha Kolesnik, a tech worker and fiction writer, who had believed she married a widower. In May 2023, detectives brought Nick to Georgia for questioning. He told a story of being pursued and harassed by unknown actors tied to past Pentagon work. He said a man calling himself Jim McIntyre, claiming to be an FBI agent, had come to their home and exerted control over their lives, telling them when to move and what to do. Nick claimed they obeyed Jim for years, believing he was protecting them.
Detectives grew skeptical and began building a circumstantial case. Surveillance from a remote pumping station recorded a green Ford Explorer — matching Nick’s vehicle — driving near the property where Mindi’s remains were found. Frost checked retailers and matched the Milwaukee-brand knife found at the scene to a purchase from a Home Depot 50 minutes from the hunting club, bought with a debit card tied to Nick. Surveillance photos show a man identified as Nick with the knife after paying for it. Records also tied Nick to a Bass Pro Shop purchase of a seven-piece field-dressing kit and a bone saw. Subpoenaed phone records and the vehicle’s GPS placed Nick’s phone and car at the same location where the body was recovered.
During interrogation, Nick gave conflicting accounts about Mindi’s last days. He claimed she had reported a fall and checked into a clinic around Thanksgiving 2022; when he arrived to retrieve her, he said, a doctor told him she had died suddenly. He could not provide names, locations, or details of the facility. He insisted he had asked to see her but said he was not allowed. He denied killing Mindi and suggested the mystery man Jim McIntyre might be responsible.
Prosecutors argued Nick fabricated elaborate stories to cover his tracks. They pointed to physical evidence tying him to the crime scene: his vehicle, his phone, and purchases of knives and tools consistent with dismemberment and field dressing. Laurie Baio told jurors the knife found near Mindi’s body matched the brand Nick bought and that surveillance showed him with it on the day investigators believed Mindi may have been killed. Investigators who searched for Jim McIntyre located one local man by that name who managed a dental implant company; he was not an FBI agent and had no discernible connection to the case. The prosecution submitted there was no credible evidence a federal agent named Jim McIntyre controlled the couple, contending Jim was a fabrication.
The defense painted Nick as a frightened man manipulated by a mysterious figure. Defense attorney Doug Weinstein described Nick as “a man who lived in fear” and argued he had been duped and deluded, not a killer. Nick testified that he had given this Jim McIntyre access to their lives and bank accounts and that he believed McIntyre was who he claimed to be. The defense offered no photographs, records, or independent evidence of McIntyre; Weinstein acknowledged he had no proof that McIntyre existed beyond Nick’s testimony.
Witnesses painted a mixed portrait of Nick. Some former colleagues and friends, including retired Commander Cameron Nelson, described him as a decorated, helpful officer who stepped up in hard situations. Others recounted being financially deceived. Cameron testified that she lent Nick money and gave him a credit card after he said his accounts were hacked; she said he charged about $198,000 and never repaid it. Heather Thomas testified Nick failed to comply with the divorce judgment ordering payment to her. Nick’s third wife Samantha testified she felt “horrified, shocked … traumatized, violated, deceived” upon learning Nick had misled her about his past and Mindi’s status.
The prosecution argued motive lay in betrayal and control. Laurie Baio acknowledged motive was the hardest question but told jurors she believed Nick wanted a family and had learned Mindi was not pregnant; Mindi’s death certificate later showed she was not pregnant. Baio urged jurors to focus on the evidence and Mindi’s life rather than the defendant’s narratives. The defense reiterated the case was circumstantial and said the state had to prove guilt beyond a reasonable doubt.
After deliberating just over an hour, the jury convicted Nick Kassotis on all counts, including malice and felony murder. The judge sentenced him to life without parole. At sentencing, friends and family expressed the betrayal they felt. Morgan Paddock addressed Nick directly: “She loved you and trusted you to tell her the truth, to protect her, to live out your marriage vows. And yet you were the one that she needed protection from.”
The case hinged largely on circumstantial evidence and Nick’s contradictory statements, his travel and phone records, and retail surveillance tying him to purchases and locations connected to the crime. The alleged puppet master, Jim McIntyre, never materialized in court as a corroborating witness. Mindi’s friends and family now remember her for her podcast, her efforts to highlight other women’s stories, and the life she lived before she became the center of a case that revealed layers of deception, control, and ultimately a guilty verdict against her husband.
