HARTFORD — A city man who fatally shot his sister's fiance in 2010 pleaded guilty in Superior Court Monday to first-degree manslaughter.

Akeem Pottinger pleaded guilty under the Alford doctrine. With Alford pleas, the defendant doesn't admit guilt but acknowledges there is enough evidence for a conviction.

The original charges against him included murder; the reduced charge was the result of a plea agreement. The sentencing is scheduled for Sept. 8.

Pottinger had to be extradited from Virginia two months after the homicide.

Police said he fatally shot Stephen Wynn on Feb. 27, 2010 at Pottinger's Sargeant Street apartment,.

According to the warrant for his arrest, Pottinger was upset over the way Wynn, his sister's fiance, had reprimanded Pottinger's niece. Wynn had punched holes in Pottinger's closet door while yelling at the girl, and then left the apartment, the warrant said.

Pottinger's sister told police she was lying down in her bedroom when she heard Wynn and Pottinger arguing. She went out to tell them to stop and, as she returned to her bedroom, she heard three gunshots, the warrant says.

She told police Wynn was on the living room floor bleeding from the face.

One of the children told police she had attempted to stop the argument by wedging herself between the two men. When they didn't stop arguing, she went to the dining room and watched as Pottinger shot Wynn, the warrant states.

Pottinger had said he was trying to defend the girl and other children who were in the home at the time, prosecutor Thomas Garcia said outside of court.
