SAN ANTONIO – A threatening message referencing a possible school shooting, discovered in a restroom at Nimitz Middle School earlier this week, has been determined to be “not a credible threat,” according to school officials and police.
The message was reported by a student on the afternoon of April 20 after it was found written inside a girls’ restroom stall. According to a letter sent to parents, the graffiti read: “Tiroteo Mañana 4/21/2026, chao perras, están listas perras,” which translates to “Shooting tomorrow 4/21/2026, bye dogs, be ready dogs.”
“We immediately notified the North East Police Department (NEPD) and they are investigating,” said the letter.
In a follow-up letter sent April 21, it was determined the threat was not credible.
“Based on information gathered, NEPD does not believe this was a credible threat,” said the letter.
“We have reviewed camera footage and conducted interviews. However, at this time we have not been able to identify the person or people responsible.”
District officials said additional police officers were present on campus as a precaution. School leaders are also urging families to speak with students about the seriousness of threats.
Parents with questions or tips are asked to contact the school at (210) 356-5300.
