<p>SALEM, Ore. — Oregon’s attorney general and a district attorney announced Thursday that a joint investigation will be conducted into the police killing of Robert Delgado in Portland. </p>
<p>The shooting occurred April 16 after a 911 caller reported Delgado had been seen practicing quick-draws in a park with what looked like a pistol but was not pointing it at anyone.</p>
<p>Minutes after officers arrived, Officer Zachary DeLong shot and killed Delgado. It turned out the handgun was a replica. </p>
<p>Attorney General Ellen Rosenblum and Multnomah County District Attorney Mike Schmidt expect a grand jury will determine if the use of deadly force was a legal act of self-defense or defense of others.</p>
<p>The investigation will begin after a police probe is concluded. The Portland Police Association union did not immediately respond to a request for comment.</p>
<p>Delgado’s family previously called for an independent investigation of the shooting. Their attorney, J. Ashlee Albies, has said video of the encounter and witness accounts are “deeply disturbing and alarming.”</p>
<p>“We see that Robert is having a mental health crisis,” she said. “He is clearly struggling to keep his composure and we hear the way that the police were responding.”</p>
<p>DeLong fired at Delgado from behind a tree about 90 feet away. </p>
<p>Delgado suffered from anxiety and depression and had been living outside and staying with friends, according to his family and court records, the Oregonian/OregonLive has reported. His sister said he struggled with substance abuse addiction.</p>
<p>Rosenblum will assign an assistant attorney general to work with two Multnomah County deputy district attorneys to oversee the criminal investigation. </p>
