37 Tex. Admin. Code § 9.82 - Local Law Enforcement Responsibility
A local law enforcement agency with jurisdiction over the investigation of a killed or a seriously injured officer may submit a request for activation of the Blue Alert network. The request must be submitted using the appropriate Texas Department of Public Safety (DPS) form, available on the DPS website. A local law enforcement agency may submit the form after it has verified that all statutory criteria for activation are clearly established by the specific facts of the case. Local law enforcement shall provide a detailed description of the missing suspect and, if applicable, any available portion of the license plate number of a motor vehicle used by the suspect.
