The Limestone County Sheriff’s Office tells CBS 42 that the 9mm handgun allegedly used by the shooter was in the house illegally, but has now been found. Sheriff’s confirm that the 14-year-old was assisting them in locating the weapon.

According to investigators, the 14-year-old shooter told authorities that he was in the basement when he heard shots. When questioned by Sheriff’s, inconsistencies in his story emerged. Ultimately, he confessed to the shooting.

The shooter was a student at Elkmont High School and officials with Limestone County Schools say extra counselors will be on campus for as long as needed.

Tragedies of this nature are uncommon in Elkmont, which according to the Census Bureau has a population of less than 500.

It’s quiet. It’s peaceful.

That’s why resident Karen Middleton has called it home for the last 11 years. “[Elkmont is] very friendly. Everybody says ‘hi’ whether you know them or not,” said Middleton.

That’s why this incident is so shocking to many, including officials.

“[This is] a tragedy on a scale that we are not used to here,” said Stephen Young, Public Information Officer for the Limestone County Sheriff’s Office. “This is going to have a ripple effect among family. Among friends. Upon the local community in the Elkmont area.”

Members of the community have recognized the pervasive impact Monday night’s events have had on the community.

Thom Porter, the Senior Pastor at Elkmont United Methodist Church, tells CBS 42 that Tuesday afternoon, 10 pastors and 20 residents from around the area were inside his church praying for the family.

Tuesday at 7 P.M., he’s hosting a public vigil.

“The ripple effect affects more than just their particular family. It affects their neighbors, their neighbors’ neighbors, their extended family, their school, it affects everybody,” said Porter. “We’re just trying to help out.”

But for people like Middleton, there’s still only one feeling that can be articulated.

“Right now, it’s shock. Everybody is in total shock,” said Middleton. “As a community, we’re just reeling with shock right now.”
