After a brief hearing Thursday morning, a Fauquier County Circuit Court judge approved the full reimbursement of $39,856 in expert services for the prosecution of a man convicted of first-degree murder in the 2017 shooting death of a Warrenton CVS store manager.

A jury on Aug. 3, 2018, convicted Bernard C. Duse Jr. of the execution-style killing of Rex Mack Olsen, 64, of Culpeper, in the parking lot the Warrenton CVS on Blackwell Road. The jury also sentenced Mr. Duse, 78, of Alexandria, to life in prison.

The commonwealth’s attorney office sought the reimbursement on behalf of the Town of Warrenton, which paid three firms for cellular phone data analysis, DNA evidence analysis and expert testimony during last summer’s five-day trial.

Deputy Commonwealth’s Attorney Jamey Cook on July 10 first asked Judge Herman A. Whisenant Jr. to authorize the use of state funds to pay for the expert services costs.

But, Judge Whisenant, who presided over the Duse trial, postponed a decision on the request until Ms. Cook could provide additional details about the consultants’ work.

Ms. Cook recently submitted to the court a three-page memo detailing the expenses.

Judge Whisenant reviewed the memo with Ms. Cook, noting the amount each consultant would receive and the combined total for their services. The Aug. 8 hearing lasted about four minutes.

Based on court documents:

• Pittsburgh-based Cybergenetics, which processed, analyzed and documented DNA evidence, received $23,306.

• Morrisville, N.C.-based Envista Forensics, which provided cellular data analysis, received $8,375.

• Bartonville, Texas-based Hawk Analytics, which provided cellular data analysis and two days of expert testimony, received $8,175.
