Collin County District Attorney Greg Willis announced that Jhirrell Harris, 44, of Monroe, Louisiana, has been sentenced to life in prison without the possibility of parole after being convicted of Capital Murder in the fatal 2023 shooting outside a Walmart in Frisco.
On the night of November 15, 2023, Frisco police responded to reports of shots fired at the Walmart on Preston Road. Officers discovered two victims: 62-year-old customer Dung Doan, who later died from his injuries, and 22-year-old Army veteran and Walmart employee Zachary Lowe, who was on a break at the time and survived.
Doan had recently immigrated to the United States with his family and was building a new life in North Texas when the crime occurred.
Detectives Kyle Marks and Sanja Trtanj of the Frisco Police Department led the investigation, which revealed that Harris and an accomplice planned a robbery that turned deadly. Cellular mapping, forensic testing, social media records, and an anonymous tip to Frisco PD’s 411Tip line tied Harris and his accomplice to the crime. Records also showed Harris fired the murder weapon in Louisiana just weeks later.
After a three-day trial, a Collin County jury found Harris guilty. Judge Benjamin Smith handed down the mandatory sentence of life without parole under Texas law.
“Harris was a menace whose cold-blooded violence stole the life of an innocent man and left a young Army veteran wounded outside a neighborhood Walmart,” said DA Greg Willis. “Collin County and beyond are safer tonight with him locked up for good.”
The case was prosecuted by Assistant Criminal District Attorneys Dewey Mitchell and Christina Skipper, with support from District Attorney Investigator Laurie Gibbs and Victim Assistance Coordinator Melissa White.
