TUCSON, Ariz. (AP) – The supervisor of a drug unit at the Sierra Vista Police Department has been forced to resign after it was discovered that he was having a sexual relationship with a confidential informant and that he took her cell phone out of evidence.
Acting police chief Adam Thrasher said Cpl. Michael Mitchell began the relationship around May and that the department learned about it in July.
An investigation revealed that Mitchell had taken the informant’s cell phone out of a truck that was in evidence.
Mitchell could not be reached for comment. He resigned at the end of October after being told he was being fired.
Thrasher said that about 17 felony drug cases were dropped because Mitchell, who was a necessary witness, had been on leave pending the investigation.
