On April 23, 2021, Delgado's family asked Oregon Governor
Kate Brown, Oregon Attorney General
Ellen Rosenblum, and Multnomah County District Attorney
Mike Schmidt to appoint a special prosecutor to the criminal investigation of Officer DeLong. That request was joined by community organizations including the Oregon Justice Resource Center, the Mental Health Association of Portland, and the ACLU of Oregon. Other organizations, such as the Mental Health Alliance were outraged by the killing. On the afternoon of April 23, the Delgado family was joined by over 200 community members for a peaceful memorial gathering at Lents Park. Also on April 23, the police bureau denied a media request for an un-redacted version of the 18 minute 911 audio. Schmidt affirmed the PPB denial saying that, as of May 25, releasing the audio was premature. On April 27, Portland Police chief
Chuck Lovell said the Bureau would cooperate with any review of the deadly shooting, including a special prosecutor appointed by the state's attorney general. On April 28, Rosenblum and Schmidt announced there would be a joint investigation into the death of Delgado. == Grand jury ==
