  Minister of Communications, Infrastructure and Housing Miguel Ángel Díaz Bobadilla initiated an investigation that revealed the bus had been active for 30 years but still had a valid license to operate. He said that the cause of the accident was still unknown and that investigators were looking into whether the bus was overloaded with passengers.
  
  Investigators said they would check if the driver could have lost control due to brake fade.
  
  On the same day, the Public Ministry of Guatemala (Ministerio Público, MP) requested a post-mortem examination on the body of Billy Aníbal Foronda Azañón, the 24-year-old bus driver, to detect the presence of possible drugs. Preliminary investigations determined that his driver's license was for light noncommercial vehicles, not mass transit. The bus also was at an unapproved route.
  
  In addition, police found a gun in the wreckage, raising speculation that the driver may have been threatened with the gun. National Civil Police deputy director-general Helver Beltetón said the weapon was registered to a deceased passenger who worked as a private security guard, adding that "the brakes could have failed but we're also not ruling out an accident or a criminal act; all that will be investigated".
  
  By February 15, the wreckage still remained at the accident site as the MP prosecutors continued to inspect it.
