From an article:

The 17-year-old son of a man who was found shot to death Monday at a home near Abita Springs is being held in the St. Tammany Parish jail on two counts of first-degree murder, and has not been granted bond, St. Tammany Parish Sheriff Jack Strain's office said Tuesday.

Jacob Middleton Jr., of 1601 Haring Road in Metairie, is accused of fatally shooting his father, Jacob Middleton Sr., 35, and his 2-year-old half-sister, Makayla Middleton. ...

The younger Middleton admitted to shooting his dad and half-sister, when questioned by investigators early Tuesday, Strain said in a press release. Strain would not say whether investigators found a weapon at the crime scene.

Jacob Middleton Jr. "indicated that his actions were the result of, among other things, his hatred of his father for what he claimed was years of abuse and family violence," Strain said.
St. Tammany Parish court records show Jacob Middleton Jr.'s parents divorced in 2011.

In 2010, a 22nd Judicial District Court judge granted Middleton's mother a protective order that prevented Jacob Middleton Sr. from going within 100 yards of her home, court records show. In her petition requesting a protective order, Middleton's ex-wife claimed he slapped, choked, shoved and threatened her with bodily harm and with a weapon.

Strain said Monday that deputies been called to the Carnation Street home in the past for domestic violence and mental health issues.

The article did not state how the teen got the gun and ammo.
