San Diego Police Officer Eric Oberndorfer arrived to a pharmacy in Mission Valley on August 28, 2015 and found suspect Robert Hober walking toward him, armed with a box cutter.

In the span of eight seconds, Oberndorfer commanded Hober to “put the knife down”, took at least eight steps back from the approaching suspect and fired his weapon twice.

The encounter captured on the officer’s body camera was one of several video clips released Friday by San Diego County District Attorney Bonnie Dumanis as part of her department’s review of 10 officer-involved shootings in 2014-2015.

“In each and every one of these incidents, the individuals failed to comply with the officer’s commands,” Dumanis said, adding the videos often contain graphic language and images.

Hober, a 54-year-old transient, was shot in the legs and torso by two bullets. He died from his injuries.

A pharmacy employee was on the phone with police when shots were heard in the background. The employee told the dispatcher, "Now he's going towards them with the box cutter," according to the DA's review.

Investigators found the box cutter on the ground in the area where the officer was standing.

The investigation concluded Hober "posed a significant threat" to the officer and that Oberndorfer's actions were justified. Read the report here.

Toxicology test results showed Hober's blood-alcohol level at 0.15 percent.

In releasing video and information of the other investigations, Dumanis said seven individuals had drugs in their systems at the time they were shot. At least three were suicide by cop, she said.

In May, District Attorney Bonnie Dumanis publicly released video evidence including personal body camera footage of officers for the first time.

She acknowledged that the policy of sharing such video evidence was new and unfamiliar but necessary "in a world where all kinds of video evidence is becoming more and more prevalent."

District Attorney Bonnie Dumanis briefs media on the investigations into 10 shootings across San Diego County on June 3, 2016.

The policy of how to release the videos has not been finalized, according to Dumanis.

They are still drafting and crafting a policy for releasing video of officer involved shootings.

“The whole purpose of doing this again, as we did a couple of weeks ago, is so the public can review what we’ve done and give us feedback. And after each, we hope to again, maybe implement that into our policy,” Dumanis said Friday.

She says, so far, community feedback has been positive.

“Most of that framework has been embraced by the community. The only thing that always comes up, and I suggest it would probably come up from you too (media), is ‘we want the video yesterday. We want it right away,’” she said.

Public feedback sessions to solicit citizen involvement in formulating a policy were held last month and included San Diego Chief of Police Shelley Zimmerman and Sheriff William Gore.
