Police arrested a Lodi dentist Wednesday and were searching for her boyfriend after investigators found methamphetamine at her Fairmont Avenue dental office, Lodi police said.

Lavonne "Vonnie" Sawyer, 49, was arrested at her office after a monthlong investigation. Police want to find her boyfriend, Donald Lewis, 41.

On May 5, police visited the office, at 828 S. Fairmont Ave., because Lewis was there and had five outstanding warrants, Officer Dale Eubanks said.

When officers arrived, Lewis fled. Officers noticed liquor in the office, and staff members told investigators that Lewis would rifle through patients' medical records despite instructions not to, Eubanks said.

Following the visit last month, police contacted the state Dental Board, which opened an investigation and discovered Sawyer had dispensed about 1,000 prescriptions for medication such as Vicodin in one year. Thirty-nine of those prescriptions, investigators said, were for her boyfriend.

When investigators visited the practice, they found suspected methamphetamine hidden in a patient's medical file, Eubanks said.

Sawyer was booked on suspicion of meth possession. The Dental Board is still looking into her practice and could take further action, including revoking her license, officials said.

Lewis has outstanding warrants for charges including child abuse, battery on a spouse or cohabitant, grand theft and violating a domestic violence court order.
