A 55-year-old New Haven resident was found guilty of the brutal killings of a father and son and received a 120-year prison term in Connecticut.

The judge who oversaw the sentencing on Tuesday claimed that the case spanned more than three decades and was characterized by an exceptional amount of violence and terror.

A jury found Willie McFarland guilty of murder in November for the deaths of the two men, Fred Harris, 59, and Greg Harris, 23.

McFarland was sentenced to 60 years for each of the murders, terms that are to be served consecutively, according to a statement by New Haven State Attorney John P. Doyle Jr. The father and son were found bound and with their throats slashed in their Hamden, Connecticut, home in 1987.

Greg Harris had freed himself and tried to escape, but McFarland caught him, tied him up again and sexually assaulted him, The New York Times reported, citing the police affidavit.

Capt. Ronald Smith of the Hamden police told the newspaper the murders were “bone-chilling.”

“Any murder is horrific, but this was over the top,” he told The Times.

In handing down the sentence, Judge Elpedio N. Vitale called McFarland “an unqualified menace to society.”

McFarland quickly became a suspect and was questioned soon after the killings. But for years, authorities had no physical evidence linking him to the crime. They continued to look, conducting DNA testing around 2006 and again in 2018.

McFarland was arrested in 2019.
