Police dispatcher Heidi Feathers, 46, is under both a criminal investigation and a department personnel investigation.
The release said the search of Feathers' home stemmed from an investigation of an allegation of employee misconduct. She was arrested at about 6:30 p.m. Sept. 27 at her home in the 5100 block of Monaco Drive.
"At the residence, investigating personnel discovered illegal narcotics and drug paraphernalia. The employee was subsequently arrested for violation of section 11377 of the Health and Safety Code (possession of a controlled substance) and booked into Santa Rita County Jail," the report stated.
Capt. Craig Eicher said police found what they suspect is about two grams of methamphetamine along with prescription medications in bindles -- small packages used to hold drugs -- for which Feathers did not have a prescription.
Feathers is listed as the Police Department's shop steward for local 955 of the American Federation of State, County and Municipal Employees (AFSCME) on the local 955 website.
She was booked at Santa Rita Jail, posted bond and is on paid administrative leave pending the outcome of the case against her.
