The Alabama teen who allegedly stabbed his mother to death and severely injured his father in a violent knife-wielding attack at their home has been identified as the military couple’s eldest son, Brandon Baker.

Brandon, 17, was arrested on murder and attempted murder charges Sunday following the shocking bloodbath in which he butchered his mother, Samantha Baker, 37, and left his father, Lance Baker, 46, bloodied and begging for his life.

Cops hadn’t released the teen’s name due to his age, but a next-door neighbor in the Bladwin County neighborhood where the horror occurred confirmed to The Post on Tuesday that the suspected killer arrested was Brandon, the couple’s oldest of their two sons.

A social media account run by Samantha also confirms that her son Brandon is 17 — the age of the suspect provided by cops — and a rising senior in high school. 

The Facebook page painted the image of a beaming family of four with her as a doting mother to her two boys, who gushed over her alleged killer son’s junior prom photos and fretted over him growing up too quickly — calling him “my baby.”

Samantha, who worked as a realtor, frequently posted photos of her family regularly attending high school football games and church services to the joint Facebook account with Lance.

“Welcome to the Baker house. We laugh then holler then act like nothing happened until it’s time to holler and laugh again. It’s a s*** show over here. Enter at your own risk,” she lovingly joked in one post. 

On Brandon’s birthday last September, she affectionately wrote, “Happy birthday to my first born! 17 years has flown by! You are an amazing person and yet at the same time you make my blood boil…I love you, B!”

In another post, the mother-of-two wrote that she prays that the couple “raise our boys to be men of God, respectful husband, patient fathers and good friends.”

Samantha and Lance Baker were found with multiple stab wounds outside their private Belforest community home around 9 p.m. Sunday, WALA reported.

The matriarch of the family was pronounced dead at the scene while her husband — who ran door-to-door for help, leaving behind a trail of blood — remains in critical condition in the hospital. He was heard screaming that he “didn’t want to die,” according to traumatized neighbors.

The married couple, who had met while serving in the US Army Reserve, had attempted to flee Brandon’s knife-wielding attack that erupted after an argument over their discipline of the teen, the outlet reported. 

The 17-year-old had allegedly stabbed his parents inside and outside their family home before barricading himself and calling 911, according to the Baldwin County Sheriff’s Office.

The family’s younger teenage son was not at the home at the time of the attack, police said.

Brandon is being held on a $1 million bond following his arraignment on Monday. He is expected to be tried as an adult.
