HARRIS COUNTY, Texas (KTRK) -- A 15-year-old is charged with murdering his father, but the boy's family says it's a case of self-defense.

On May 5 around 3:45 a.m., police say officers responded to a family disturbance on the 21400 block of Sagrantino Court in west Harris County after a woman called 911.

The sheriff's office says there was an altercation between the woman's estranged husband, 35-year-old Samson Hernandez, who no longer lived at the home, and her boyfriend.
