HARGILL (January 1, 2013)--A preliminary investigation into a mobile home fire that killed three young children indicates the likely cause was an electrical problem, Hidalgo County Sheriff Lupe Trevino said.
Trevino said investigators found no evidence of accelerants that would suggest arson and space heaters in the home also did not cause the fire early Sunday morning.
Trevino speculated that the family may have been running extension cords from one trailer to the other.
The side-by-side mobile homes were engulfed in flames when firefighters arrived.
Trevino says the victims were 15-day-old Victorino Robledo, 1-year-old Angelica Robledo and Salvador Robledo, 3.
The children's parents and grandfather were taken to San Antonio for treatment of burns and smoke inhalation.
