Police, school districts investigating threats on social media

There is an increased police presence at southern Denton County middle and high schools on Friday morning as police departments and school administrations investigate possible threats of gun violence that are circulating on social media.

In an email to families, Lewisville ISD acknowledged “a concerning message posted to social media that is circulating and being reposted in numerous areas of the LISD community, with various campus names attached to it.”

The district assured families that it is taking the situation seriously and working with police to investigate fully. The Lewisville Police Department has been working with LISD since the first threat was made toward a Lewisville school on Wednesday. More threats have surfaced since, and all of them have been determined to be non-credible, a Lewisville police spokesman said, and there have been similar non-credible threats on social media throughout the country. However, out of an abundance of caution, the district wanted to keep families informed and have an increased police presence at several campuses.

Lewisville police discredited a new social media post on Friday afternoon that falsely claimed there was a violent incident involving a car crash on Main Street.

LISD asked families to report, not repost, concerning information.

iSchool of Lewisville informed families that its campus will be on a modified lockdown and have an increased police presence on Friday due to a threat on social media.

Guyer High School families received an email saying that there had been a vague social media threat that doesn’t name the school, but Denton police and the district are investigating and there would be an increased police presence at school on Friday.

Marcus High School, one of the schools that was named in some of the social media posts, had a large number of student absences Friday and canceled the scheduled pep rally.

“Days like today are difficult and take an emotional toll on everyone, but we are prepared and we are here for your students to guide them through this day and in the days ahead,” Marcus Principal Will Skelton said in a letter to families.
