A Texas truck driver kidnapped and killed an Army veteran last year before dumping her body in the woods — and on Thursday, he learned that he would spend the rest of his life behind bars.

Naasson Hazzard, 28, of Austin, was convicted by a jury in February of kidnapping resulting in death, which carries a mandatory sentence of life imprisonment. Once that sentence was made official on Thursday, authorities honored the completion of the case as well as the victim, Caleigha Zangari, an Army veteran and San Diego-area mother.

“The tremendous, relentless work of multiple law enforcement partners brought the terrible acts of this predator to light, and the jury answered the call for justice by finding him guilty,” acting U.S. Attorney for the Northern District of Texas Nancy Larson said in a United States Attorney’s Office press release. “Now, the life sentence he will serve reflects the value and sanctity of this victim’s life. We hope that this sentence helps her family in the healing process.”

On Aug. 15, 2024, Zangari entered Hazzard’s semi-truck in Dallas at about 9:30 p.m., according to surveillance video evidence presented during the trial. She was believed to be a sex worker who had traveled from California to Texas with her child the week of Aug. 5, 2024, according to an arrest affidavit for Hazzard.

On Aug. 21, 2024, the San Diego County Sheriff’s Office relayed to Homeland Security Investigations’ North Texas Trafficking Task Force that Zangari and her son had been reported as missing persons at risk. Two days later, on Aug. 23, 2024, her body was found in a wooded area around Pittsburg, Texas, with a black plastic bag tied around her head.

Authorities did not release a cause of death. It is also unclear what happened to the victim’s son. Law&Crime reached out to the U.S. Attorney’s Office for additional information.

Cell phone records proved to be investigators’ biggest lead. They found that Zangari, who had posted advertisements online in the preceding days, had communicated with a number about 13 times in the two days before she was kidnapped, according to the affidavit. That number belonged to Hazzard.

Investigators obtained Hazzard’s cell phone records and found that he traveled from the pickup location in Dallas to a parking lot nearby and remained there for 17 minutes. He is said to have then driven more than three hours to the wooded area east of Dallas, where he texted his boss that he would be taking a sick day the following day. He then remained in that area for nearly an hour.

Prosecutors detailed how the next day, Hazzard and his wife returned to the scene in Pittsburg, before going to dinner in Tyler, which is located about an hour south.

The coming days were revealing for investigators. Hazzard is said to have switched cell phones, deleted his Google and Life360 location sharing accounts, cleaned his truck with bleach, and searched online for: “how many years for first second and third degree murders.”

His wife appeared to have had suspicions, reportedly searching, “Pittsburg Texas news.”

The same day Zangari’s body was found, her cell phone was located shattered on the side of the road on the route Hazzard drove on the night of Aug. 15, prosecutors said.
