Authorities say the 25-year-old boyfriend of a Long View woman killed her 1-year-old son and hurt her 3-year-old daughter while babysitting them.
Investigators said William Lail was charged with murder and two counts of intentional child abuse inflicting serious injury after being questioned Friday night.
Authorities say Lail came out of the home around 1 p.m. Friday, holding the boy and screaming for help. Police have not released details of what caused his death.
Witnesses say the 3-year-old girl appeared to suffer burns. She was taken to the hospital. Her condition has not been released.
Lail was seen crying in a patrol car after the children were taken away. He remains in jail, and it wasn't known if he has an attorney.
