KCBS’ Bob Melrose Reports:

This news comes as the San Francisco District Attorney’s Office prepares to prosecute a domestic violence case involving Sheriff Ross Mirkarimi, who is facing misdemeanor charges of domestic violence battery, child endangerment and dissuading a witness, all stemming from an incident involving his wife, Eliana Lopez, on New Year’s Eve.

Mirkarimi has pleaded not guilty in the case and Lopez denies that any violence occurred.

Nikaein helped prosecute the case of a wheelchair-bound homeless man accused of assaulting a San Francisco police officer with a knife last January.

Police fired two shots at the defendant in that case, Randall Duncan, after prosecutors said he disobeyed repeated orders to drop the knife. The jury ultimately acquitted Duncan of the assault charges.

A spokesperson for the San Francisco District Attorney’s Office said the California Attorney General’s Office is handling the investigation.
