"We'd like to identify that individual to see if he can help us learn what the vehicle's registered owner's activities were," said Sgt. Frank Bell of the /*San Bernardino County Sheriff's Department*/.
Investigators passed out fliers with the man's image at the shopping center hoping someone can identify the man.
Detectives said they are treating the discovery of a body found inside the burning Porsche as a homicide.
The SUV's owner withdrew a large sum of money, investigators said.
