On Thursday, officers from several surrounding towns descended on Bellmead Thursday morning. Soon after setting up a perimeter around Dauzat’s mobile home, authorities made contact with the young father, who barricaded himself inside his mobile home with his two young children, ages 1 and 2.

Ultimately, authorities convinced Dauzat to surrender, after which he allegedly emerged covered in blood, the spokesman says.

The children are now in the state’s custody, according to police spokesman.
