The active-duty Green Beret behind the suicide bombing in a Tesla Cybertruck in Las Vegas and the Army veteran who plowed a truck through a crowd in New Orleans on New Year’s Day had a brief overlap in their service at Fort Liberty, North Carolina.

However, despite their shared history at the base, formerly Fort Bragg, law enforcement officials have said there’s no evidence the two events were linked. The men, Master Sgt. Matthew Livelsberger and Shamsud-Din Jabbar, who were both killed in the incidents, never served in the same unit, according to unit histories provided by the Army.

Livelsberger was a Special Forces operator, serving most of his time in 10th Special Forces Group in Germany and Fort Carson, Colorado, with a short stint in the National Guard’s 19th Group in Columbus, Ohio. Jabbar, who pledged allegiance to the Islamic State terrorist group, had spent his Army career in support roles, serving as an information technology specialist with the 82nd Airborne Division at Fort Liberty and what is now the 11th Airborne Division in Fort Richardson, Alaska. He left the service as a staff sergeant in 2020 after 12 years.

Livelsberger served at Fort Liberty from December 2012 to October 2013, supporting the school that trains upcoming Green Berets, according to service records. Jabbar served at the base from June 2012 to January 2015 with the 82nd Airborne Division’s Headquarters and Headquarters Company, 1st Brigade Combat Team.

Fort Liberty is a big base and one of the Army’s most high-profile installations, serving as the headquarters for its special operations forces and the 82nd Airborne — both among the most prestigious organizations in the service. More than 50,000 soldiers are assigned there.

“At this point, there is no definitive link between the attack here in New Orleans and the one in Las Vegas,” FBI Deputy Assistant Director Christopher Raia said Thursday.

The two men also deployed to Afghanistan simultaneously in 2009, with Jabbar in the 25th Infantry Division when the division’s 4th Brigade Combat Team was operating in the volatile Paktika and Paktia provinces. That element of the 25th Infantry has since been redesignated as the 11th Airborne Division.

Livelsberger’s military career spanned nearly two decades, including nine deployments to Afghanistan, Tajikistan, Congo, the Republic of Georgia and Ukraine before Russia’s invasion.

In a series of notes Livelsberger wrote ahead of his death, he outlined political and cultural grievances on a wide range of domestic and international topics.

“Americans only pay attention to spectacles and violence. What better way to get my point across than a stunt with fireworks and explosives?” Livelsberger, who died from a self-inflicted gunshot wound before detonating the truck bomb, wrote in a note released by police Friday. “Why did I personally do it now? I need to cleanse my mind of the brothers I’ve lost and relieve myself of the burden of the lives I took.”

A former girlfriend told multiple news outlets that Livelsberger’s behavior shifted in 2019 after a deployment abroad, during which she says he suffered traumatic brain injuries. Those injuries can have devastating symptoms and are linked to increased risk of suicide.

Livelsberger received mental health treatment through the Army, according to Brig. Gen. Amanda Azubuike, a spokesperson for the service.

“We encourage our soldiers, if they need help, mental health treatment or need to speak with someone, to seek proactive behavioral health treatment,” Azubuike said in a statement.
