Carroll High School and Carroll Senior High School are both closed Wednesday due to a threat.

An anonymous report of a potential threat was received overnight, according to a CISD social media post.

The Southlake Police Department will conduct a “thorough investigation,” per the post. “The threat was isolated to CHS; however, due to the scheduling of students who take classes at each campus, we are closing both out of an abundance of caution.”

The report was received through the district’s STOPit System. It involved a message that was written on a bathroom stall door referring to the STAAR test and a potential school shooting, according to a news release from the Southlake PD.

No additional details about the potential threat were provided by the school district or police.

Community members are asked to contact Southlake PD if they have any information regarding the potential threat. All other campuses across the district are open and continuing with normal operations.

A number of school-related threats and violent incidents have been reported in the DFW area recently.

Classes were canceled at Roosevelt High School in Oak Cliff on April 26 following a drive-by shooting the previous evening where two students were shot, as covered by The Dallas Express. Dallas ISD canceled classes the next day, citing what they called a “credible threat,” according to a social media post from the district.

On April 24, a student at Bowie High School in Arlington was fatally shot by another student, as covered by The Dallas Express.

The shooter was identified as 17-year-old Julian Howard, who allegedly took the life of 18-year-old Etavion Barnes just before the school dismissed for the day. Howard was arrested and booked into the Arlington City Jail on a murder charge after allegedly shooting Barnes five or six times.

A 17-year-old student was shot in the upper thigh by another student in the bathroom at Wilmer-Hutchins High School on April 12, The Dallas Express reported. New details from the chief of Dallas ISD’s police department found that school staff did not follow proper backpack search and metal detector protocols, which allowed the student to smuggle the gun into the school.

Chief Albert Martinez told The Dallas Morning News that though the metal detectors went off, “there wasn’t a challenge. There weren’t the secondary steps that should have happened. And that’s our concern.”

In June 2023, Gov. Greg Abbott signed HB3 into law, requiring campuses across the state to have an armed security guard on campus beginning with the 2023-24 school year.

Since the start of this school year, Dallas ISD has had difficulty complying with the new law, citing a lack of security guards and funding. Last August, the district was short 167 armed officers, according to Fox 4 KDFW.
