The firefighters department in the city of Balsas says the victims are an elderly woman, her daughter, grandson, the pilot and a nurse.
The three residents of the home where the small plane was crashed today escaped any injuries. The family told local media the plane crashed into their 11-year-old son's room, but he had asked his parents to let him sleep in their bed yesterday night.
The plane was taking the patient and her family from Balsas to a hospital in the city of Teresina.
