A Bluff man has been charged with attempted homicide after Pittsburgh police said he wrote a letter to a detective confessing to a shooting last year.

Timothy Wynn, 21, was arraigned this afternoon on charges of attempted homicide, aggravated assault, conspiracy and other crimes.

Pittsburgh police wrote in a criminal complaint that Mr. Wynn wrote a letter to a detective earlier this month and then agreed to an interview.

During the interview, Mr. Wynn told police that he was in a parking lot near Crucible Street in Crafton Heights on April 19, 2012, when a man named Michael Thomas walked past and rudely asked, "What's up?"

Mr. Wynn told police that he didn't like the way Mr. Thomas responded when Mr. Wynn asked him where he was from.

Mr. Wynn told police he pointed a gun at Mr. Thomas, ordered him to the ground, stole his Chicago Bulls hat and wallet and then shot Mr. Thomas and ran away.

Two others -- Deron Taylor, 29, and Andrew Howard, 21 -- were also charged in connection with the shooting. Both are awaiting trial, according to online court records.
