He was charged with <a href="http://globalnews.ca/news/3371673/david-dao-drug-offenses-united-airlines-overbooked/" target="_blank">98 counts</a> of illegally prescribing and trafficking painkillers. He was then convicted in 2004 and placed under a 5 year supervised probation. </p><p>His questionable behavior didn't stop with his drug charges. It was discovered that he was sexually pursuing a male patient, Brian Case who he knew from church. This included performing unnecessary physical examinations, writing prescriptions he didn't need and eventually hiring him as his office manager. The man eventually left his job after filing a criminal complaint indicated that Dao arranged to provide him with prescription drugs in exchange for sex. </p><p><!-- [invalid-shortcode] --></p><p>Dr. Dao was arrested when Case, who was 26 at the time- less than half the doctor's age, agreed to go undercover. After being caught with his shirt off and his pants unbuckled, he denied what was about to occur. </p><p>Due to these transgressions, his medical licence was suspended in 2003, and was eventually reinstated in 2016 after completing workshops and undergoing psychological evaluations. During his evaluations he stated that regaining his medical licence was a matter of "family honor". 4 of his 5 children are doctors. His wife Teresa is a pediatrician, their eldest son Tim practices medicine in Texas, their second son Ben is a medical graduate, their daughter Christine is a doctor in Durham NC, and their youngest daughter Angela is a medical graduate of the University of Kentucky.
