A Texas man sought in the deaths of two children who were discovered inside a burning car was found dead Monday, officials said.

The Cooke County Sheriff's Office has said in a Facebook post that 37-year-old Mandeep Singh of Fort Worth was sought after a vehicle was discovered Sunday on fire in the middle of a roadway in the rural northwest area of the county about 18 miles northwest of Gainesville.

Firefighters put out the flames and discovered the bodies of the two children in the backseat.

A relative told FOX4 the victims were two children, ages 3 and 5, and that Singh was their father.

Authorities initially said Singh was considered to be "armed and dangerous" before his body was discovered in a wooded area on Monday not far from where the car was discovered burning.

No additional details were given about what may have caused him to kill his children.

Court records obtained by FOX4 said that Singh was charged with family violence in 2016 and received two years deferred adjudication.
