Horace Dexter McDade, a revenue technician, and John Vincent Haile, an ex-Metro Transit Police officer, are set to appear before U.S. District Judge Leonie M. Brinkema at 2 p.m. in Alexandria.

McDade’s job was to collect bills and coins from fare machines and truck the cash to a collection facility in Alexandria, while Haile stood guard. Authorities say the two stashed bags of money for their own use and had been conspiring since at least 2010, according to an affidavit . Both men have since been fired. McDade had worked for Metro since February 1979. Haile had worked for the Metro Transit Police since August 1997.

Haile used stolen money to buy Virginia Lottery tickets — sometimes paying with bags of change, authorities said. Between October and December, he used more than $28,000 in coins and cash to purchase tickets, according to the affidavit. Records from the Virginia Lottery show that Haile won nearly $63,000 in the past few years.

Attorneys for McDade and Haile had asked a judge to delay indictments earlier this year, saying they were exploring plea agreements.

Metro brought in Deloitte, the accounting and professional services firm, to do a forensic review of its revenue center and processes. That audit is ongoing, according to a spokesman. Transit Police Chief Michael Taborn and the transit authority’s inspector general also are conducting reviews.
