Texas Medical Board suspends doctor arrested in connection with East Texan's death

TYLER, Texas (KETK) - A doctor connected to the death of an East Texan has been suspended by the Texas Medical Board.

On July 6, Howard Gregg Diamond, 56, was indicted and charged with conspiracy to distribute controlled substances, possession with intent to distribute controlled substances, health care fraud and aiding and abetting and money laundering and aiding and abetting. The indictment indicates an alleged pattern of practice which includes prescribing dangerous controlled substances with a risk of abuse and diversion for no legitimate medical purpose.

According to the indictment, beginning in 2010, Dr. Diamond is alleged to have conspired with others to write prescriptions for substances such as hydrocodone, oxymorphine, methadone, fentanyl, morphine, oxycodone, alprazolam and zolpidem, without a legitimate medical purpose. The conspiracy is alleged to have resulted in the overdose deaths of at least seven individuals from 2012 to 2016. Those deaths occurred in Sulphur Springs, McKinney and Abilene. He's also connected to deaths in Ardmore, Oklahoma; Idabel, Oklahoma; Yukon, Oklahoma; and Hugo, Oklahoma.  

On Thursday, the disciplinary panel of the Texas Medical Board suspended Dr. Diamond after determining his continuation in the practice of medicine poses a continuing threat to public welfare. The suspension was effective immediately.

Dr. Diamond appeared at detention hearings on July 14 and 18, 2017. He has requested release from jail, but as of the drafting of the temporary suspension/restriction application, staff has reason to believe Dr. Diamond remains incarcerated.

The TMB says a temporary suspension hearing with notice will be held as soon as practicable with 10 days' notice to Dr. Diamond, unless the hearing is specifically waived by Dr. Diamond.

The temporary suspension remains in place until the board takes further action.


Dr. Diamond's stepdaughter was found dead in a creek over the weekend.

According to Fox 4, Dallas police found the body of Mikayla Mitchell, 17, floating in a creek at Blair Park in Dallas on Sunday. Fox 4 reports a friend of Mitchell's said her body had been tortured and dismembered.

Relatives of Mitchell say her death has nothing to do with her stepfather's case, according to Fox 4.

An investigation into Mitchell's death is underway. If you have any information regarding this case, please contact the Dallas Police Department.
