A Phoenix man has been sentenced to 20 years in prison after a jury found him guilty of second‑degree murder in the shooting death of his roommate inside a west Phoenix group home. The case stems from Jan. 25, 2024, when officers were called to a transitional‑living house and found a resident shot in a stairwell. Prosecutors identified the defendant as 37‑year‑old Michael Lanunziata and the victim as Joseph Lephiew.
Maricopa County Attorney Rachel Mitchell announced the sentence, calling the killing “a deadly and unjustified act of violence inside a place where people should have felt safe,” as reported by Arizona's Family. The outlet reports that Lanunziata received a 20‑year term following his conviction for second‑degree murder. Mitchell’s statement characterized the shooting as an escalation that began when Lanunziata brought a gun into the shared home.
According to a Phoenix Police media advisory from the Phoenix Police Department, the shooting occurred the night of Jan. 25, 2024, near 43rd Avenue and Encanto Boulevard. Officers responding to the scene found the wounded man on a stairwell and later took Lanunziata into custody after he exited the residence through a second‑story window. The advisory says police recovered a handgun at the top of the staircase along with multiple shell casings.
Lanunziata told investigators the victim “came at him” and claimed he fired in self‑defense. Other residents, however, reported hearing an argument followed by several gunshots, and prosecutors said those eyewitness accounts, combined with the physical evidence, undercut the self‑defense narrative. He was ultimately charged with and convicted of second‑degree murder, the verdict that led to Monday’s 20‑year sentence, according to Arizona's Family.
What the charge means in Arizona
Under Arizona law, second‑degree murder applies to killings that are not premeditated but involve an intent to cause death, knowing conduct that results in death, or reckless behavior that shows extreme indifference to human life. The offense is classified as a class 1 felony, and sentencing guidelines for a first‑time offender range from a minimum of 10 years to a presumptive term of 16 years and a maximum of 25 years in prison. Those ranges are outlined in A.R.S. § 13‑1104 and the sentencing table in A.R.S. § 13‑710.
Context: congregate living and safety
Officials said the house was operating as a transitional‑living residence and that five men were living there at the time, a setup that can raise recurring questions about oversight and access to firearms in shared housing environments. Hoodline previously covered Lanunziata’s January 2024 arrest and the initial police response in West Phoenix in its report on the fatal West Phoenix shooting.
Prosecutors described Monday’s sentence as holding Lanunziata accountable for a killing that rattled the small household, while court records will contain the full legal filings and the judge’s remarks for anyone seeking a more granular look at how the case played out in the courtroom.
