An explosion rocked the Trump International Hotel in Las Vegas on Wednesday morning, killing one person and injuring at least seven others.
The blast came from a Tesla Cybertruck parked near the entrance.
Officials are investigating whether the incident is linked to the earlier attack in New Orleans that killed 15 people.
Authorities found gas cans, fireworks and camping fuel in the truck's bed, but it's still unclear how the explosion occurred.
The Cybertruck driver died in the explosion, and his identity is still being confirmed.
Sheriff Kevin McMahill assured the public that there is no ongoing threat but stressed that the investigation is still in its early stages.
Federal agencies are also looking into whether the incident could be considered an act of terrorism.
The Cybertruck, rented through the Turo app in Colorado, was tracked through charging station footage.
The same app was used to rent the vehicles involved in the New Orleans attack.
Tesla CEO Elon Musk said the explosion was caused by materials in the truck, not the vehicle itself.
