A dozen more cases involving a former Philadelphia narcotics officer are being dismissed by the district attorney.

A judge had already overturned 53 convictions based on testimony from Jeffrey Walker.

Walker was arrested in May. An FBI sting allegedly caught him plotting to rip off drug dealers.

Prosecutors continue to investigate Walker's involvement in other drug cases.

Pending the investigtion, it could lead to more of those cases being dismissed.
