Denise Hart was a 24-year-old mother from Hartford, Connecticut, who traveled to Sudbury, Vermont, in January 2015 to visit friends. She spoke daily with her mother until the calls abruptly stopped on January 25, 2015, the last day anyone is known to have seen her. On January 26 a car she had been driving was found burning in a remote area of Cornwall, Vermont.

Months passed with no sign of Denise. On December 22, 2015, a dog walker found human remains in a wooded area in Goshen, Vermont. An autopsy identified the remains as Denise Hart and determined the cause of death was a gunshot wound to the head; the death was ruled a homicide.

Early in the inquiry, the friend Denise had been staying with, Josh Preseau, was the last known person to see her and was treated as a person of interest; he told investigators she left his residence on January 25 to meet someone, cooperated with police, took a polygraph, and was later cleared. Preseau pointed investigators to two other men, Chris Richards and Todd Norris, who allegedly made comments about eliminating competition; authorities questioned them but no arrests have been announced and the case remains unsolved.

Did anyone in the Sudbury or Cornwall area at the time notice Denise or her car around January 25?
