Los Angeles firefighters are fighting two grass fires bracketing Interstate 405 to the southbound 118 in the San Fernando Valley.
The fire broke out in a homeless encampment on one side of the 405, before spreading across the highway to two more locations.
A body was found in the camp by fire crews. An investigation is underway by police detectives from Devonshire Station.
The fires erupted Wednesday morning, close to residential neighborhoods.
A view from KABC-TV's news helicopter shows the fires appear to be confined to roadside landscaping, although one of the fires sent up high flames.
According to Officer Leland Tang of the California Highway Patrol, one lane is closed on the 405 and a separate LAPD investigation is underway.
Units are still on the scene, according to police. At least two units of the CHP and one unit of the LAPD are investigating. The fire itself has mostly been contained.
Correction: An earlier version of this story said that the fire killed one person; it's unclear if the person was killed by the fire or was already dead.
