During the afternoon of April 15, 1986, 36-year old Lynda Moore (b. April 20, 1949) was doing yard work outside her home in Saxtons River, Vermont, a short distance from I-91. That evening, her husband returned home to find his wife's dead body, bearing multiple stab wounds. The crime scene suggested a fierce struggle had taken place.

Numerous witnesses reported having seen a slightly stocky, dark-haired man with a blue knapsack lingering near Moore's home the day of the murder. The man was thought to be between 20 and 25 years old, clean shaven, with a somewhat round face, and wearing dark-rimmed glasses. The following year, a composite sketch was released.

, Boroski then saw the driver of the vehicle walking around the back of her vehicle. He then approached her open window and asked her if the pay phone was working, at which time he immediately grabbed her and pulled her from the vehicle. Boroski struggled, and the man accused her of beating up his girlfriend and asked if she had Massachusetts plates on her car. Boroski responded that she had New Hampshire plates, but this did not deter her attacker, who proceeded to stab her 27 times before driving away and leaving her to die.

Boroski managed to return to her car and drive on Route 32 toward a friend's house for help. As she neared the house, she noticed a vehicle driving in front of her and realized that it was her attacker. Boroski finally reached her friend's home at which the occupants immediately came to her aid. Her attacker apparently performed a u-turn and slowly passed by the house as Boroski was tended to before speeding away into the night.

Boroski was treated at the hospital, where it was determined that the attack had resulted in a severed jugular vein

, regarded Michael Nicholaou as strange and quiet. As his marriage to Michelle became more troubled, Michelle attempted to leave him, taking her two children with her. This prompted Nicholaou to pursue Michelle's whereabouts, making contact with her family during this period. Michelle, who told family members that she feared for her life, eventually returned to Nicholaou, but expressed intentions to family to leave him for good. In December 1988, Michelle's mother dropped by the home of Michael and Michelle to check on her daughter after weeks of no contact; she found spoiled food in the refrigerator, an abandoned baby book, and the apartment vacant. There was no trace of Michelle, Nicholaou, or the two children.

Carty read about the tragedy in the newspaper and was compelled to investigate Nicholaou's past, as well as explore other New England crimes around the time of Michelle's disappearance. It was then that Carty began reading about the Connecticut River Valley killings and suspected that Nicholaou could have been the perpetrator. Among many points of interest to Carty was that one of Nicholaou's ex-wives was a nurse, a profession shared with three of the Connecticut River Valley victims.

While Nicholaou's residence in Holyoke was about 90 miles (144.8 km) from Claremont, Carty was able to determine that Michelle had relatives in the area, and a note in the abandoned baby book placed her in 1986 at the same Hanover, New Hampshire

Hanover is a town along the Connecticut River in Grafton County, New Hampshire, United States. The population was 11,260 at the 2010 census. CNN and Money magazine rated Hanover the sixth best place to live in America in 2011, and the second best in 2007....

, hospital from which Barbara Agnew would disappear a short time later. It was also determined that Michael Nicholaou owned a Jeep Wagoneer on August 6, 1988, which is consistent with the vehicle described by Jane Boroski.

Carty began communicating with Boroski shortly after Nicholaou's murder-suicide (both were interviewed in a 2008 episode of THS Investigates: Serial Killers on the Loose that focused on the Connecticut River Valley killer). Carty shared her findings about Nicholaou with Boroski. Boroski was shown pictures of Michael Nicholaou and expressed that there was "some resemblance" between him and the man that attacked her. The culmination of Carty's interactions with Boroski was that Boroski is now convinced that Michael Nicholaou was her attacker and, by extension, the Connecticut River Valley killer.

New Hampshire cold case detectives, in 2007, stated that they were in the process of examining surviving physical evidence, as well as Michael Nicholaou's possible connection to the case. To date, no conclusions have been publicly announced, and Nicholaou has not been conclusively linked to the crimes of the Connecticut River Valley killer.

It's worth noting that Nicholaou's candidacy as a suspect is hampered by the fact that he appears to have been living in Virginia at the time of the Courtemanche, Fried, and Morse murders (reinforced by the date of his obscenity trial), and likely both up to and beyond that time. Furthermore, online sleuths have variously posited Nicholaou as being the Colonial Parkway Killer

There is no physical or compelling circumstantial evidence presently available to the public which factually connects Nicholaou to any of the "Connecticut River Valley" cases or other case in VT or NH beyond his slight resemblance to some sketches.

 and set out to Vermont, where they abducted, murdered, and dumped 38-year old Barbara Agnew, who had long been considered a victim of the Connecticut River Valley killer.

Westover provided the names of the three friends and Minnon recorded them on a piece of scrap paper. Thereafter, Minnon shared Westover's information with his wife, daughter, and law enforcement. Minnon felt, however, that authorities were not interested in his information. Westover died in March 1998, and Minnon died in 2006.

In August 2006, one of Westover's aunts wrote Anne Agnew, sister of the victim, with the information originally given by Westover to Minnon. Agnew forwarded the letter to Carty, who ran the name of Michael Nicholaou by Westover's aunt, who stated that the named "sounded familiar." Carty believes that authorities are in possession of the names Westover provided to Minnon, and further speculated that Westover may have become acquainted with Nicholaou at an area Veterans Affairs hospital, although none of this has been confirmed and the Connecticut River Valley killings remain unsolved.
