A Jefferson Parish judge on Wednesday (Sept. 3) sentenced Michael A. Harris to two back-to-back life sentences for his conviction of shooting a couple from the back seat of a pickup truck parked in a Marrero home’s driveway. 

Harris, 36, of Terrytown, was convicted by a jury on Aug. 1 of two counts of first-degree murder in the deaths of David Sumera, 36, and Alexxis Eymard, 26. 

Sumera was driving a rented 4-door Ford Ranger that he had borrowed and was delivering heroin to someone in the 2600 block of Bay Adams Drive on the afternoon of Sept. 24, 2022. Eymard sat to his right in the front passenger’s seat. Behind her sat Harris, who was acquainted with the couple. 

Armed with a 9mm semiautomatic pistol and without provocation, Harris shot the Belle Chasse couple in the backs of their heads at about 1:45 p.m., minutes after they pulled into the driveway.  

“Their last moments on Earth were filled with the smell of gun smoke and the sound of gunfire,” Assistant District Attorney Matt Clauss told jurors in opening statements. 

For four hours, their bodies remained in the pickup, its engine running, until the woman who lived at the Bay Adams Drive residence found them and called 911. The woman, who slept through much of the day, did not hear the gunfire. She did notice the pickup in her driveway at one point during the day and assumed Sumera was in the neighborhood. 

Jefferson Parish Sheriff’s Office detectives canvased the neighborhood in search of residences with video surveillance systems. They found videos showing the pickup being driven into the driveway. 

Minutes later, Harris, concealing his identity with a cloth over his head, got out of the rear passenger’s side door, video shows. He opened the front passenger door, stayed there momentarily, closed it and then walked around to do the same to the driver’s side. 

Surveillance video also shows him walking away into the neighborhood carrying a black bag, similar to one that Sumera owned. Nearby, Harris is seen in surveillance video rummaging through that bag before making his escape.  

Harris walked on and discarded the cloth in the street. Upon seeing this video recording, detectives immediately recovered the cloth. It was a shirt. On it, Sheriff’s Office Crime Lab DNA analysts found genetic material consistent with Harris’s. 

The analysts also found DNA consistent with Harris’s on the rear passenger’s side door handle, where the shooter was seen stepping out of the pickup. 

Detectives learned that Sumera and Harris were acquainted. Days before the murders, a witness socialized with Eymard, Sumera and a man introduced to her as “Mike.” The witness then drove “Mike” to his home in the 800 block of Mystic Avenue in Terrytown – Harris’s home. 

Additionally, geolocation data obtained from the pickup truck’s infotainment system and from a cell phone that Harris used at the time suggested that Harris and Sumera were together in the hours leading up to the murder. Harris stopped using that phone shortly after he committed the murders.  

Armed with an arrest warrant for the murders, a U.S. Marshals fugitive task force located and arrested Harris in Memphis, Tenn., on Feb. 16, 2023. He was armed with a 9mm pistol and apparently was living on the streets. That pistol he had in Memphis was not the murder weapon, which has not been found. 

In addition to the two murders, the jury found Harris guilty of being a convicted felon in possession of the firearm used in the homicides. He was prohibited from possessing firearms because of his convictions of possession of heroin and distribution of heroin, both in Jefferson Parish. 

During the trial, Harris’s attorneys challenged the evidence linking him to the murders, saying there were no eyewitnesses and that Harris’s DNA could have been left on evidence at any time prior to the murders. The attorneys suggested that Sumera might have been targeted by someone other than Harris because of the assistance he had given to law enforcement previously. 

The jury deliberated almost three hours before reaching their verdicts on Aug. 1. 

In victim-impact testimony given during Wednesday’s sentencing hearing, Sumera’s younger sister and the mother of his child to the court that he was not perfect. But he didn’t deserve to be murdered by a man he considered a friend, they said. 

“David was my protector through a traumatic childhood,” his sister testified. “He made me feel safe. He made me feel loved. Now because of the choices made by the man sitting before you, that safety is gone.” 

The mother of his son said he “made a lot of mistakes in his life … but his life mattered.” 

“He was kind,” she said. “He was funny. He was talented. He was loved.” 

“You didn’t just take David’s life. You shattered ours,” she told Harris. 

After denying a defense motion for a new trial, Judge Raymond Steib of the 24th Judicial District Court on Wednesday sentenced Harris to life in prison without benefit of probation, parole or suspension of sentence for each of the two murder counts. He ran the sentences consecutively. 

Judge Steib also sentenced Harris to 20 years for the conviction of being a felon in possession of a firearm. That sentence was run concurrent with the two life sentences. 

Assistant District Attorneys Matt Clauss and Theresa King prosecuted the case.
