Michael Lanunziata was convicted after prosecutors said the evidence contradicted his account.
PHOENIX, Ariz. — A fatal shooting inside a west Phoenix transitional home ended with a 20-year prison sentence for Michael Lanunziata, whose claim of self-defense was rejected by a Maricopa County jury.
The case began not in a public place, but inside a shared residence near 42nd Drive and McDowell Road. Joseph Lephiew and Lanunziata had lived there together for about one year, along with other adult male residents. Prosecutors said the home was meant to provide transitional living space, but on Jan. 25, 2024, it became the scene of a deadly argument, a staircase shooting and a murder case that turned on the location of a gun, shell casings and Lephiew’s body.
Police responded after multiple 911 calls reported a shooting at the residence. When officers arrived, Lanunziata did not meet them at the front door. Prosecutors said he had gone out through a second-story window and onto the roof, where he spoke with first responders for several minutes. He told them there was one gun in the house and that it belonged to him. Officers then entered the home and found Lephiew on the stairs. He had been shot multiple times and was pronounced dead at the scene. “The defendant chose to bring a gun into that home, escalate a conflict, and take a life,” County Attorney Rachel Mitchell said after the sentence was announced.
The staircase became central to the case. Officers found Lanunziata’s handgun at the top of the stairs and shell casings nearby. Prosecutors said Lephiew was unarmed and that there was no evidence of any weapon near his body. Other residents told investigators they heard an argument, followed by multiple gunshots. The county attorney’s office said evidence confirmed the shooting happened on the staircase, placing the physical record against Lanunziata’s account that Lephiew “came at him.” Prosecutors said his later statements were inconsistent. They described his explanation as a story shaped after the fact rather than an account supported by the scene.
Lanunziata was charged with second-degree murder, a class one dangerous felony. A jury found him guilty before sentencing. The 20-year prison term gave prosecutors the outcome they sought after arguing that the killing was not legally justified. Mitchell called the shooting “a deadly and unjustified act of violence inside a place where people should have felt safe.” That statement reflected the county’s framing of the case: a residential conflict that did not end with a fight broken up by housemates or police, but with one resident dead and another on the roof while officers moved through the home.
The setting also separated the case from many public self-defense claims. The shooting did not unfold at a bar, parking lot or street corner. It happened in a house where the men lived, a place where residents shared space and where ordinary conflict could turn dangerous if a firearm entered the argument. Prosecutors released limited information about what the men argued over. They did not describe a long-running dispute, a specific threat before the shooting or a weapon in Lephiew’s hands. The known evidence, as described by the county attorney’s office, focused instead on the unarmed victim, the defendant’s gun and the shell casings found at the top of the stairs.
Lanunziata’s history gave the prosecution and the public another point of reference. In 2016, he was accused in a fatal shooting in Henderson, Nevada, after Lamar Reid Jr. was killed at a townhouse. Local reporting at the time identified Reid as a relative of former U.S. Sen. Harry Reid. Lanunziata said he acted in self-defense in that case, too. Clark County District Attorney Steve Wolfson later said the evidence did not support a murder prosecution that could be proved beyond a reasonable doubt. A witness disputed that conclusion in public comments, but charges were dropped and Lanunziata was not convicted in Reid’s death.
The Nevada decision did not control the Arizona verdict. The Phoenix case had its own scene, witnesses, gun evidence and jury. Still, the comparison was striking: two fatal shootings involving housemates, two self-defense claims, and two very different legal endings. In Nevada, prosecutors said a knife found under Reid’s body supported Lanunziata’s account. In Phoenix, prosecutors said no weapon was found near Lephiew. In Nevada, the case was dismissed. In Arizona, a jury convicted Lanunziata and a judge imposed a two-decade term. The difference underscored how self-defense cases often turn on physical evidence as much as on what a defendant says.
After sentencing, Lanunziata was moved into state prison custody, and records cited by local reporting placed his projected release in 2041. The Maricopa County Attorney’s Office did not announce any further hearings tied to the case. For Lephiew’s family and the men who were inside the home that day, the court process has moved from trial to punishment, but the sentence does not change the facts prosecutors emphasized: the argument, the gunshots, the unarmed victim and the staircase where the shooting ended.
The case now sits in the post-conviction stage, with Lanunziata serving a 20-year sentence and no additional charges announced in the Phoenix shooting.
