The city of New Haven and its police department are facing more litigation with a lawsuit on behalf of a man falsely imprisoned for nearly two decades for a murder he did not commit.

Marquis Jackson’s March 13 federal lawsuit comes six months after his friend, Vernon Horn, filed a similar claim. The two men had their murder convictions vacated on the recommendation of New Haven State’s Attorney Pat Griffin, who said publicly the state no longer had confidence that the men were responsible for the crimes for which they were convicted.
