GREENBELT, Md. (AP) — A real estate developer has been sentenced to two years in prison for his role in a bribery scheme involving former Prince George’s County Executive Jack Johnson.

Sixty-four-year-old Daniel Colton was sentenced Tuesday in federal court in Greenbelt.

Colton was involved in a project around the Greenbelt Metro station. Court documents show he and other co-conspirators gave more than $400,000 in cash and gifts to public officials, including James Johnson, the former county housing director.

Colton’s guilty plea was unsealed following Jack Johnson’s guilty plea in 2011 to corruption charges. He was the last of 17 defendants to be sentenced for their roles in what prosecutors called a “pay-to-play culture” in the county during Johnson’s two terms.

Colton previously served three years in federal prison for conspiracy and bank fraud.
