The Texas Education Agency is no longer investigating San Antonio Independent School District's outgoing superintendent after he was accused of failing to report educator misconduct, according to a letter from the agency shared with KSAT Investigates.

The district and superintendent Jaime Aquino received the letter one day after the TEA confirmed to KSAT it had opened an investigation earlier this month.

In a letter sent to Aquino on Wednesday, the TEA said it closed the case after the agency determined the allegations were "unsubstantiated." KSAT Investigates checked Aquino's educator certificate on Wednesday, which shows there is no longer a flag stating that his educator certificate is under review.
