Three people were killed and another person was injured in a fiery crash in Piedmont early Wednesday morning, police said.
The wreck happened at about 3 a.m. in the area of Hampton Road and King Avenue, according to police.
At 3:08 a.m., the 911 dispatch center received an alert from an iPhone indicating that a collision occurred, Piedmont police Chief Jeremy Bowers said. A short time later, a member of the public called 911 and reported that there had been a crash and a vehicle was on fire.
First responders found the Cybertruck engulfed in flames.
"Our officers applied their fire extinguishers in an attempt to extinguish the flames, but the fire was too intense for the extinguishers to be effective," Bowers said.
Four people were inside the truck. Three died at the scene. The fourth person was pulled out of the truck by a member of the public and taken to a local hospital in serious condition, Bowers said.

Video footage from the scene showed the mangled Cybertruck wedged between a retaining wall and a tree.
The cause of the crash is being investigated, but preliminary information suggests speed played a role.
"It's safe to say that speed was a factor," Bowers said. "Now are there other factors associated? That is certainly possible, but speed is likely a contributing factor in this collision."
Bowers said the investigation is in its infancy, adding that details could change.
"I want to keep the focus on the victims and the families that lost their loved ones," Bowers said. "I will tell you that our women and men who responded to this call did everything they could. It's devastating. The devastation pales in comparison to what these families are dealing with this morning the day before Thanksgiving."
