Chief Homer Delgado said the department has turned over the footage to the district attorney’s office and ordered an investigation into how the error occurred.

Officials in Uvalde revealed on Wednesday that they failed to release some officer body camera and dashboard footage related to the 2022 Robb Elementary School shooting as required by a settlement agreement with news organizations that sued for access.

After the city released hundreds of records on Saturday to news organizations, including ProPublica and The Texas Tribune, an officer informed the Uvalde Police Department that some of his body camera footage from the May 24, 2022, shooting was missing, according to a news release from the city.

In response, police Chief Homer Delgado ordered an audit of the department’s servers, which turned up “several additional videos.” The city did not say which officers or cruisers the missing footage belonged to.
