State fire authorities are investigating a New Year's Day blaze in a mobile home in West Texas that left three people dead, including an infant.
Motley County Sheriff's officials say a fire in a fireplace and small heaters were being used at the trailer home in Matador, about 70 miles northeast of Lubbock, but the state fire marshal's office would look into finding a cause.
A relative of the victims says his nephew, the nephew's fiance and their 1-month-old child died in the blaze.
Three other people managed to flee the burning home. The sheriff's office says the fire is not being investigated as a crime.
