A Tonawanda man has pleaded guilty to second-degree murder for killing his wife with a hammer at a Cleveland Drive residence, but the criminal case remains pending until sentencing. Police found her body during a middle-of-the-night 911 call just months earlier. Nicholas M. Malvaso, 37, admitted in court this past Friday that he intentionally struck 51-year-old Tiffany L. Malvaso with a hammer, ending her life at a residence in Tonawanda.
Malvaso entered his plea on September 25, 2026, before New York State Supreme Court Justice Kelly Vacco in Erie County, according to Syracuse.com. He had been indicted by an Erie County grand jury following his arrest in May, and per Frontpage Detectives, he remains held at the Erie County Holding Center without bail as he awaits sentencing.
According to the Erie County District Attorney's Office, Malvaso intentionally killed his wife by striking her with a hammer. District Attorney Michael J. Keane's office confirmed the plea, and Malvaso now faces a maximum sentence of 25 years to life in prison, per Syracuse.com.
A 2:45 a.m. Call Led Police to a Body
Police and paramedics responded to a 911 call at 2:45 a.m. on May 16, 2026, and found Tiffany Malvaso dead inside the residence on the 300 block of Cleveland Drive in Tonawanda, according to Syracuse.com. The Erie County Medical Examiner's Office determined she died from blunt force trauma to the head and neck and ruled her death a homicide.
Tiffany Malvaso was found at a Cleveland Drive residence. Nicholas Malvaso was a member of the United States Air Force at the time of his arrest.
Defense Dropped an Intoxication Argument
Early in the court proceedings in May 2026, defense counsel for Malvaso had signaled plans to argue he lacked the intent to kill due to severe intoxication, an argument reported by the Buffalo News. Malvaso later pleaded guilty to intentional second-degree murder. Under New York law, second-degree murder is codified under Penal Law § 125.25 and classified as a Class A-I felony, the state's highest felony severity level, according to Konta Georges & Buza P.C.
New York Penal Law § 70.00 mandates that a Class A-I felony conviction for second-degree murder carry an indeterminate prison sentence of 15 years to life, with parole eligibility beginning only after the court-ordered minimum is served, per the same firm's explainer. Formal sentencing for Malvaso is scheduled for Tuesday, November 24, 2026, at 11:00 a.m., according to Frontpage Detectives.
Investigators Recognized for Homicide Case
Following the plea, the Erie County District Attorney's Office recognized Town of Tonawanda Police Department Detectives Robert Kubus, Mark Muscoreil, Mark Shell, and Joseph Kazmark, along with Officers Justin Okun and Nick Thomas, for leading the homicide investigation, Frontpage Detectives reported.
Part of a Troubling Regional Pattern
Domestic violence numbers in Western New York have been rising even as overall crime has gone down, and domestic homicides have been described as an area of concern, according to Buffalo Toronto Public Media. A Family Justice Center official has discussed rising domestic violence numbers, domestic homicides and safe places to go.
The Erie County Sheriff's Office maintains a specialized Domestic Violence Unit that follows up on every Domestic Incident Report filed by law enforcement in the county, offering crisis intervention and safety planning resources, according to the Erie County Sheriff's Office.
