The State Fire Marshall’s Office is investigating a residential fire in the City of Blue Earth over the weekend that claimed 2 lives. The fire at the home on East First Street in Blue Earth was reported at just before 5am Sunday morning. When firefighters arrived they found the bodies of the home’s resident, 39-year-old Rudy Carmona, and his cousin, 47-year-old Fidel Bello of Elmore. Autopsies to determine their causes of death are being performed. An initial investigation found the cause of the fire may have been a lightning strike to the home, which authorities say had no functioning smoke detectors.
