Defendant Admitted Replacing Diverted Drugs with Saline, Impacting Treatment of More Than 200 Animals

PORTLAND, Ore. — Dr. Brenda Brown-Carlson, a Portland veterinarian, was sentenced to 60 months of supervised probation on January 13, 2026, in Multnomah County Circuit Court as part of a plea agreement. Brown-Carlson admitted to diverting controlled substances for her personal use and replacing them with saline, impacting the treatment of more than 200 animals at two veterinary clinics where she was employed.

“DEA has a long-standing relationship of trust and partnership with veterinary providers who are authorized to handle and administer controlled substance to care for animals that are sick,” said Robert A. Saccone, Special Agent in Charge, DEA Seattle Field Division. “ Ms. Brown-Carlson abused that relationship and trust by diverting prescription drugs for her own personal use and, in doing so, compromised the care of more than 200 animals.”

Brown-Carlson pled guilty to one felony count of Tampering with Drug Records, two felony counts of Computer Crimes, and one felony count of Attempted Animal Neglect in the Second Degree.

According to court documents, Brown-Carlson diverted hydromorphone, a Schedule II controlled substance,  buprenorphine, a Schedule III controlled substance, and butorphanol, a Schedule IV controlled substance, for her own use. Rather than administering the appropriate doses of these medications, animals undergoing surgery and medical procedures received diluted doses, compromising their care.

Co-workers became aware of drug discrepancies and reviewed the clinics’ computerized drug-dispensing machine, records, and surveillance video. Video footage showed Brown-Carlson diverting controlled substances and refilling vials with saline.

The veterinary clinic reported the diversion to the Drug Enforcement Administration (DEA) in Portland in February 2024. A Diversion Investigator from the DEA Seattle Field Division, Portland District Office, initiated an investigation and reviewed the evidence. During an interview, Brown-Carlson initially denied the diversion, even after being shown video evidence, and later admitted to the conduct, showing little remorse. She surrendered her DEA Certificate of Registration during the interview.

Following testimony by the DEA Diversion Investigator before a Multnomah County Grand Jury, a state indictment was issued. Brown-Carlson was arrested and charged with 14 felony counts of Tampering with Drug Records, 13 felony counts of Computer Crimes, and two felony counts of Animal Neglect in the Second Degree, involving more than 40 animals.

As part of the plea agreement, Brown-Carlson ultimately pled guilty to reduced charges and was sentenced to 60 months of supervised probation. Conditions of probation prohibit her from being employed by any business whose primary purpose is the treatment of animals. She is also prohibited from having contact with animals during probation, except that she may own and care for her own pets. She may not provide veterinary care for her own pets or for the pets of others, and may only have contact with other pets in the presence of their owners.

“This sentence makes clear that drug-related crime has consequences, but it also acknowledges that meaningful accountability includes addressing addiction through structured treatment to reduce the risk of re-offending in the future,” said Multnomah County District Attorney Nathan Vasquez.

Action by the Oregon Veterinary Medical Examining Board regarding Brown-Carlson’s state veterinary license is pending. Civil penalties for violations of the Controlled Substances Act related to her DEA Certificate of Registration are also pending.

The OCHC is comprised of seven citizens. It is empowered by the Legislature to maintain a listing of all historic cemeteries in Oregon, make recommendations for funding, seek legislative appropriations for historic cemeteries, and assist in the coordination of restoration, renovation and maintenance of historic cemeteries statewide. The commission develops online resources, offers workshops, and promotes the value of historic cemeteries through storytelling.
 

The group meets four times per year in different locations around the state and online. There may be an occasional additional meeting for extra projects, programs, and grant selection. Commissioners are also asked to organize informal meetings in their regions or work on other projects outside of meeting time. Travel costs are reimbursed.
