Simi Doctor under investigation for death related to over-prescribing drugs

troche arial, case sans-serif;”>On May 28, 2015, the Ventura County Interagency Pharmaceutical Crimes Unit (PCU) continued their investigation into a Simi Valley physician regarding claims of over-prescribing opiate and other controlled substance medication.

A search warrant was served at Dr. Matzner’s Simi Valley office. Numerous medical files and other items of evidentiary value were seized during the service of the warrant. The search was related to a several month investigation centered on the amount of prescription drugs coming from Dr. Matzner’s office. The investigation revealed Dr. Matzner’s office had become a source of supply for drug seeking and drug dealing patients. During the service of the warrant, Dr. Matzner resigned his DEA registration eliminating the possibility of him legally writing prescriptions for controlled substances.

A death related to his practice of medicine is also being investigated.

The Ventura County Sheriff’s Office East County Narcotic’s Street Team assisted in the investigation.

The investigation is ongoing. Anyone with information regarding Dr. Matzner may call the Ventura County Interagency Pharmaceutical Crimes Unit at (805) 383-8700 or email [email protected]
