Derrick Jones was shot to death on November 8, 2010 by Oakland Police Officers Eriberto Perez-Angeles and Omar Daza-Quiroz.

Jones was unarmed when he was shot. Officers said they saw a metal object in his hands, which they believed was a weapon. This morning, Oakland Police identified the object as an electronic pocket scale.

Perez-Angeles and Dara-Quiroz were both involved in a previous shooting incident on July 19, 2008 that resulted in the death of Leslie Allen, according to records from the Oakland Police Department and the Alameda County District Attorney.

The Jones shooting is being investigated by the Alameda County District Attorney’s office, as well as the Homicide and Internal Affairs sections of OPD. District Attorney’s reviews often take several months to complete, and have been known to stretch on for years.  Former Chief of Police Batts asked the FBI to investigate the shooting.

Perez-Angeles is the fourth current member of OPD’s SWAT team to be involved in an officer-involved shooting since 2003, according to OPD records. Both he and Daza-Quiroz remained on paid administrative leave, which is standard practice after an officer-involved shooting.

From the February 2011 Alameda County DA’s report on the shooting of Derrick Jones:  “There is a lack of evidence to support a prosecution against eitherofficer. This office will take no further action.”
