Lamont Hines was denounced Tuesday for stabbing his wife 33 times and her aunt 13 times in an attack two years ago.
State Supreme Court Justice Deborah A. Haendiges ordered him to spend the next 30 years in prison, the maximum prison term after Hines pleaded guilty in June to two counts of second-degree attempted murder.
"You are their nightmare," Haendiges told Hines.
After Hines, 39, mumbled an apology, the judge told him she didn't believe him.
"The court does not believe you are truly remorseful," Haendiges told Hines,
She noted he had been convicted of a misdemeanor assault charge for an earlier attack on his wife.
Haendiges also cited Hines' "long and disturbing criminal history" over the past 25 years.
Caren Houston, 27, the mother of Hines' three young daughters, told the judge her nightmares "won't stop" when her now-former husband is in prison.
Houston told the judge she is still "often plagued by nightmares and anxiety attacks" over the latest assault by Hines who broke into her home and hid in a closet until she returned.
Houston's aunt, Gina Houston, was too emotionally upset to come to court for the sentencing, according to prosecutors Kristin A. St. Mary and Patrick B. Shanahan.
Defense attorney Robert Goldstein stressed to the judge that Hines suffers from mental illness and has sought help from the Buffalo Veterans Court. He served in the Navy during the first Gulf War.
Though court officials sent him for treatment, Hines was only a patient at the Niagara Falls Medical Center for five days before being released shortly before the knife attack, Goldstein told the court.
Goldstein insisted local government agencies did not provide his client with the professional help he needed and probably still needs.
St. Mary told the judge Hines stalked his wife for 14 days before the knife attack, which she called "the ultimate domestic violence case" and "one of the most deliberate and violent" crimes she has ever seen as a prosecutor.
Both victims "continue to be haunted" by the attack despite medical care and psychological counseling, both prosecutors told the judge.
After the sentencing, Victoria Houston said Hines damaged her car and her Buffalo house a day before the knife attack on her granddaughter, Caren Houston, who had lived with Hines about four years and married him only months before the attack.
