Shortly after the secretariat he heads announced the discovery of the single-engine Cessna 208-B, which disappeared Monday, Ruiz Esparza said on Twitter that regrettably there were no survivors.
The wreckage of the airplane was spotted by a helicopter Wednesday in the Sierra de la Giganta mountain range just west of the Loreto airport, where it took off Monday morning, the secretariat said in a statement.
The airplane was carrying 13 passengers and one pilot.
A search-and-rescue mission was launched Monday, two hours after the plane took off, the statement added.
The airplane was carrying 13 passengers - mostly members of the same family, including two minors - and the pilot.
The aircraft, property of the private company Aeroservicio Guerrero, went missing 25 minutes after taking off from Loreto on a flight to Ciudad Constitucion, apparently due to bad weather.
The plane was authorised to fly despite adverse weather conditions in Baja California Sur state caused by Tropical Storm Octave.
