VERO BEACH, Fla.--Two people are dead following a travel trailer fire in Vero Beach Friday morning.
Now, fire investigators are trying to determine what caused the deadly fire, and determine who was inside the trailer.
Fire officials say the fire started around 6 a.m.
Minutes after the fire was controlled, investigators say they found two bodies and the body of a pit bull.
Neighbors woke up to watch fire crews battle the fire.
"I opened my blinds and I see there's a fire so I grabbed my daughter, my wallet, my phone and my car keys," said neighbor Jerome Louis.
Louis said he didn't realize anyone was in the trailer.
Other neighbors say the homeowner where the trailer was parked would often let family or their friends sleep in the trailer.
Investigators say trailer fires are very hot, dangerous and spread quickly. Fortunately, it did not spread to any homes.
"They always have propane in them, they have paneling, things of that nature. They're made of aluminum or in most cases fiber glass which melt and burn rapidly. Very hot fires, very intense," said Indian River County Fire Asst. Fire Chief, Brian Burkeen.
Investigators say because of the condition of the bodies, they will be using dental records to make a positive identification.
The fire marshal will be determining the cause of the fire.
