Las Vegas, United States—Authorities are investigating the explosion of a Tesla Cybertruck outside the Trump International Hotel in Las Vegas as a potential act of terrorism, although the suspect’s motive remains unclear.

FBI Special Agent Spencer Evans told reporters on Thursday that agents are examining all possibilities, but no definitive ideology has been identified. "The motivation at this point is unknown," Evans said, adding that it was "not lost" on investigators that the blast occurred in front of a hotel linked to US President-elect Donald Trump, with Tesla owned by Trump supporter Elon Musk.

Gunshot wound raises suicide speculation

Authorities later revealed that the suspect, who died inside the Cybertruck, had sustained a gunshot wound to the head before the explosion. Las Vegas Sheriff Kevin McMahill said evidence from the coroner's office suggests the suspect may have died by suicide prior to the detonation.

"We also discovered through the coroner's office that the individual had sustained a gunshot wound to the head prior to the detonation of the vehicle," McMahill stated.

No link to New Orleans attack

Meanwhile, the FBI confirmed that the Las Vegas incident does not appear to be linked to the New Orleans truck-ramming attack that killed 15 people on New Year’s Day.

FBI Deputy Assistant Director Christopher Raia said during a press conference, "At this point, there is no definitive link between the attack here in New Orleans and the one in Las Vegas."

Investigations into both incidents remain ongoing.
