Dr.?Howard Gregg Diamond

SHERMAN, Texas - A North Texas doctor faces federal charges after prosecutors say he wrote unnecessary prescriptions for powerful drugs that contributed to the overdose deaths of at least seven people including one in Abilene.

Howard Gregg Diamond, 56, of Sherman, was indicted July 6 and arrested Tuesday in Sherman.

He's charged with conspiracy to distribute controlled substances, possession with intent to distribute controlled substances, health care fraud, money laundering and aiding and abetting.

The names of the victims have not been released. The indictment only includes what is believed to be the initials of the victims.

Prosecutors say Diamond began issuing prescriptions in 2010 for substances such as hydrocodone, oxymorphine, methadone, fentanyl, morphine, oxycodone, alprazolam, and zolpidem, without a legitimate medical purpose.

Those prescriptions are blamed for the overdose deaths of at least seven people from 2012 to 2016 in Abilene, McKinney, Sulphur Springs, and four cities in Oklahoma - Ardmore, Idabel, Yukon, and Hugo.

Diamond pleaded not guilty to all 21 counts. He's in the custody of U.S. Marshals and is scheduled to appear in court on Friday.

Sherman is 65 miles north of Dallas and about 240 miles northeast of Abilene.
