A 17-year-old girl and her 18-year-old boyfriend have been arrested on suspicion of killing the former's 61-year-old grandmother, Tammy King.
The woman was found dead on Thursday night, when the authorities were carrying out a security check on the house.
On Sunday, Tara King and Uriah Urek were arrested and charged with capital murder. The woman was fatally shot, but the motive for the crime remains unclear.
Neighbors reported that the elderly woman was responsible for taking care of her granddaughter, and that Urick, her boyfriend, lived with his wives in their home in Bacliff, Texas.
