An outside investigator has concluded there was “no wrongdoing” by former D.C. Mayor Adrian M. Fenty in the issuance of parks and recreation contracts to firms with ties to his administration.

The report, authorized by the D.C. Council and conducted by the law firm of Trout Cacheris, was released Monday following a yearlong investigation.

Last year, allegations Fenty steered contracts to friends and fraternity brothers became a key issue in his unsuccessful bid for reelection. But the Trout report essentially clears Fenty of doing anything illegal.

The report does recommend that the U.S. Attorney’s Office follow up with further investigation of Omar Karim and Sinclair Skinner, the contractors on the projects. The report alleges Skinner and Karim overcharged the city. It also alleges Skinner’s firm, Liberty Engineering, was not qualified to do the work.
