A former supervisor in the Baltimore City Department of Transportation pleaded guilty Friday to extortion, federal prosecutors say.

Daryl Christopher Wade, 50, of Rosedale faces up to 20 years in federal prison when sentenced Aug. 10.

Wade worked for the city from 1988 through last year, most recently as a construction project supervisor in the DOT's street cut unit, which monitors and administers fines and permits related to street cuts.

He admitted in a plea agreement to claiming he could void fines in return for payments, and accepted multiple cash payments to do so. Street cut permits are valid for 120 days, and are needed for companies who need to impede into a public right-of-way for construction. City officials assess a $50 fine per day for each street cut that isn't repaired by the expiration date.

Wade admitted that he and co-defendant Jerome Walter Stephens, the owner of a Baltimore construction and utilities company, extorted or tried to extort other businesses that either were located in Baltimore or had contracts in Baltimore. In one case, according to the plea agreement, Stephens attempted to bribe a Virginia-based underground utility construction executive who was also acting as a confidential source.

Wade himself interrupted an appeal hearing on a street cut fine to bribe a confidential source who ran a plumbing and drain construction business. In early September 2016, he met in-person with that source and agreed to accept $5,000 to remove the fine. On Sept. 22, 2016, the source paid Wade the first $3,000, throwing it into Wade's city-owned vehicle. Wade then said, "You good for life with me," laughing and later telling the source, "We in cahoots now."
