Two Edinburg Consolidated Independent School District schools were placed on a brief lockdown due to an investigation of a possible weapon at one of the campuses.

According to a news release from Edinburg CISD, the investigation of a possible weapon occurred at Robert Vela High School. Longoria Middle School was placed on a brief lockdown "out of an abundance of caution" as a result of the investigation.
