For more than a year, the state Department of Public Safety has blocked the release of records that could offer more clarity into the police response. The agency can appeal the ruling.

The ruling by 261st Civil District Court Judge Daniella DeSeta Lyttle calls on DPS to fulfill 28 records requests filed by the news organizations, which include ProPublica and The Texas Tribune, subject to redactions such as personal information of police officers and blurring the faces of minor victims in crime scene photographs.

The files would shed light on the failed police response, in which officers waited more than an hour to confront the shooter who had an AR-15-style rifle. Nineteen children and two teachers died that day.

Lyttle issued a preliminary order in June. The one issued Tuesday is the final judgment. It requires DPS to provide the records sought within 20 days, unless the state police agency appeals the ruling.
