A 14-year-old boy has confessed to killing his family of five by shooting them with a 9mm handgun in their Alabama home, cops said early Tuesday.

The teen called 911 late Monday to say he heard shooting upstairs in the house in Elkmont, according to WAFF.

Officers found five people shot, including an adult and two children who were dead at the scene.

Another adult and juvenile were airlifted to a hospital in critical condition but later died, officials confirmed.

“The 14-year old caller was interviewed and confessed to shooting all five members of his family in the residence,” the Limestone County Sheriff’s Office said in a tweet.

“He is currently assisting investigators in locating the weapon, a 9mm handgun that he said he tossed nearby.”

The dead were the teen’s father, stepmother and siblings, the sheriff told WAFF.

A motive has not yet been released.
