Sherman doctor charged in patient overdose deaths to remain jailed, for now

Howard Gregg Diamond

SHERMAN, Tex. (KXII) - An arraignment and detention hearing was held Friday morning at the federal courthouse in Sherman for the 56-year-old Sherman doctor arrested earlier this week on federal drug conspiracy charges.

Howard Gregg Diamond was indicted last week 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.

Diamond was arrested Tuesday in Sherman. At a detention hearing Friday, his attorneys asked he be released on his own recognizance on conditions, including the surrender of his medical license. But the judge did not rule, and Diamond was taken back to the Fannin County Jail.

According to the indictment, beginning in 2010, Diamond, who operates pain management centers in Sherman and Paris, 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, Texas; Ardmore, OK; McKinney, Texas; Idabel, OK; Yukon, OK; Abilene, Texas; and Hugo, OK.

The judge can rule at any time on the request of Diamond's attorney to release him on his own personal recognizance.

If convicted, Diamond faces up to life in federal prison.

Coming up tonight on News 12, hear from Diamond's attorney for the first time since his arrest.
