Man Pleads Guilty To Obstruction In Atlanta Corruption Case

An Atlanta man who threw a concrete block through a city contractor’s window and left dead rats on his porch pleaded guilty Tuesday to obstructing justice in a federal investigation into a pay-to-play scheme for city contracts.

Shandarrick Barnes, 41, was trying to keep construction contractor Elvin R. Mitchell Jr. from cooperating with investigators, federal prosecutors said. This was the fourth guilty plea in the ongoing investigation — Mitchell, another contractor and a former city official have also admitted wrongdoing.

Mitchell pleaded guilty in January to a conspiratorial bribery and money laundering charge. He was sentenced last month to serve five years in prison and ordered to pay more than $1.12 million in restitution. Mitchell’s lawyer has said he is cooperating with investigators.
