A potential tragedy averted at a Sharyland school after security officers sprang into action to protect everyone on campus.
Sharyland ISD students and employees can rest assured the security measures that the district has in place are working to protect those who study and work there.
On the morning of Tuesday, March 18, a Sharyland High School staff member received a threatening text message from her husband, Adan Diaz Jr.
"Her husband told her he was going to her place of work and he was going to kill her," Mission Police Corporal Manuel Casas said.
Casas says the woman immediately reported the threat to her supervisor and they called in back up from Mission police.
When Diaz arrived at the security gate about 45 minutes later, police were ready to protect the students.
"It was real, she feared for her life. This guy shows up, we know he is probably armed and sure enough he was," Casas said.
Mission police arrested the 44-year-old right then and there.
Diaz has since been charged with attempted criminal murder.
Over the weekend, Sharyland ISD released a statement assuring parents that students and staff were in no danger and no lockdown was ordered.
"At no time did we feel any student or staff member was in danger, Superintendent Dr. Virginia Richter said. We knew that the gentleman was coming over and we had our officers and security guards act in the proper manner so he was apprehended right there at the gate, and never allowed on campus."
Richter says this latest incident is why they review crisis management plans with the staff every year.
"We were ready to handle a situation like this. It could have been worse but because of the preparations that took place he was immediately stopped at the guard shack and never allowed on campus," Richter said.
Diaz is booked in the Hidalgo County jail on a bond of $250,000.
Every campus in Sharyland ISD has security doors that every visitor must walk through before they can reach any classroom.
