The Travis County Medical Examiner's office reversed their previous position Monday on the investigation into the police shooting of Daniel Rocha.

The ME now says Rocha did have drugs in his system when he was killed by an Austin police officer on June 16. Original toxicology reports showed no traces of drugs in his system.

"We feel very bad that this happened, but this is a very special case and it could have happened in any other office," Travis County Medical Examiner Dr. Roberto Bayardo said.

Rocha, 18, was shot in the back and killed after police say he struggled with Officer Julie Schroeder after a traffic stop in Southeast Austin.

The Travis County Medical Examiner's office said APD detectives "strongly believed" Rocha had smoked marijuana before the incident, and pushed for a different, more specific test.

"Immediately upon being notified of the results, I contacted the District Attorney's office and urged them to seize the blood and urine evidence and send it to a third party laboratory for analysis," Knee said.

"We are very disturbed, too. Exceptionally disturbed, and we are very glad that we are going to submit the specimens to another laboratory to confirm our findings," Bayardo said.

The shooting death upset many in his neighborhood. One week after the event, police and city leaders hosted a community forum. For many, it was a night to vent frustrated emotions. The forum is available on News 8 on Demand, channel 1458 on Time Warner Cable.

The Hispanic Advocates and Business Leadership of Austin hosted another panel Monday to try and rebuild that trust.

Police chief Stan Knee and Austin City Manager Tobey Futrell attended the meeting and talked with neighbors.

City leaders say the timing of the forum with the announcement of Rocha's new toxicology report was just a coincidence.
