CARTHAGE, Texas (AP) -

Investigators say an East Texas teenager has been charged with killing his stepfather to stop an attack on the youth's mother.

Panola County jail records show 17-year-old Koby Yoder of Carthage was booked Thursday on a murder charge and freed on $25,000 bond.

Sheriff's Chief Deputy John DePresca on Friday said 43-year-old Leonard Digiliormo was punching and beating his wife when her son intervened. DePresca says Yoder retrieved a handgun and fatally shot Digiliormo Wednesday night at the family's home near Carthage.

The woman's 13-year-old daughter was also present. DePresca says the mother and both teens told investigators that the woman was being attacked. She was treated and released from a hospital.

Jail records do not list an attorney for Yoder.

Carthage is 150 miles southeast of Dallas.
