DA's office to dismiss cases due to narc bust

There is more fallout from the investigation into the Contra Costa County drug task force. The District Attorney's office says it will dismiss about a dozen cases involving arrests made by Norman Wielsch, the former head of the task force.

Both Wielsch and private investigator Christopher Butler are charged with selling drugs they stole from a county evidence room and drug task force seizures.

In the meantime, the public defender says the district attorney's office should be removed from the case because of a conflict of interest.
