NEW ORLEANS — Two former Louisiana law officers with a Drug Enforcement Administration task force are facing criminal charges in a grand jury indictment made public Tuesday.

Most of the charges were lodged against 49-year-old Karl Emmett Newman of Kentwood. Among charges on the indictment are conspiracy to possess with intent to distribute cocaine and oxycodone, robbery, possessing a firearm during a crime of violence and falsifying records. Johnny Jacob Domingue, 27, of Maurepas is charged with falsifying records in a federal investigation.

Both men are former sheriff’s deputies in Tangipahoa Parish.

Both are in federal custody after pleading not guilty Tuesday, according to court records.

The indictment says Newman had been a DEA task force officer since 2003. It alleges a series of crimes by Newman that date back to 2014, continuing into early 2016. They include a drug distribution conspiracy believed to have run from August 2015 until January of this year, theft of drugs, witness tampering in an obstruction of justice count and an Aug. 14, 2015, armed robbery.

Domingue is charged with altering and making a false entry in federal records in January of this year.

Court records show that criminal charges first were lodged against the two in May. A superseding indictment was returned by a grand jury Oct. 7 and unsealed Tuesday.

A Feb. 6 trial date was set by U.S. District Judge Eldon Fallon.
