A week after state investigators searched Gary Hazen's home, the U.S Drug Enforcement Administration sought personnel files from his time as a Casper city employee, court documents show.

The DEA subpoenaed Hazen's "personnel and disciplinary files" on Nov. 14 -- four days after Wyoming law enforcement agents revealed an ongoing investigation into Natrona County's then chief deputy corner. The state investigation centers on suspicions Hazen took prescription drugs and pornography from dead people's homes.

Federal court records don't indicate the nature of the DEA's interest in Hazen. Reached Tuesday, administration spokesman Mike Turner said he couldn't comment on whether his agency, which is charged with enforcing federal drug laws, had an ongoing investigation involving Hazen.

The federal documents don't state whether the DEA's subpoena has any connection to the Wyoming Division of Criminal Investigation's case.

Laramie County District Attorney Scott Homar, the prosecutor involved in the state's case, said he couldn't comment on any means used by DCI or the federal government to obtain evidence.

"I'm not aware the federal government is looking at filing any charges in this matter," he said Tuesday afternoon. "If they are, I don't know about it."

As of Tuesday, Hazen had not been arrested or charged with any crimes. He was put on administrative leave in November and fired last month from his job at the coroner's office.

His attorney did not immediately return a call Tuesday afternoon. Hazen has not commented publicly on the charges since authorities disclosed the investigation.

On Nov. 14, the same week as that disclosure, a special agent with the Drug Enforcement Administration subpoenaed the Casper Human Resources Department for Hazen's records, according to a motion filed by the city in federal court. Hazen worked for the city as a police officer from 1978 to 1998.

The city argued Wyoming law prevented it from releasing personnel records without a court order. Its motion, filed Dec. 18, was signed by Deputy City Attorney William Chambers. He was out of the office Tuesday when the Star-Tribune tried to reach him for comment.

On Dec. 23, U.S. District Judge Clarence Brimmer ordered the city to turn over the records. He set a Monday deadline for the city to comply.

Officials with Casper and the U.S. Attorneys Office in Wyoming, which represented the DEA in the matter, declined to comment on whether the city obeyed the judge's court order. An online federal courts database did not include any entries beyond the court's Dec. 23 order.

In addition to his jobs as a police officer and deputy coroner, Hazen also worked as a Natrona County School District campus supervisor.

Natrona County Interim County Attorney Heather Duncan-Malone said she didn't know of any requests for Hazen's personnel records. Hazen was not an employee of the county commission, but rather the coroner's office. State agents conducted a search of that office in November.

School district attorney Kathleen Dixon, a former county commissioner, declined to comment on whether the DEA has asked for Hazen's personnel records for his time as a campus supervisor.

"At this time, I'm not able to answer any questions or comment on any legal documents the school district might have received from the federal government on this matter," she said.
