HARTFORD, Conn. (AP) A Connecticut judge has dismissed charges against a mentally disabled former dishwasher who was convicted of killing his wife's 88-year-old grandmother in 1987 and spent almost 26 years in prison.

Richard Lapointe's conviction was overturned in March, with the state Supreme Court ruling that prosecutors failed to disclose notes by a police officer that suggest the crime occurred when Lapointe had an alibi. He was released from prison in April.

On Friday, prosecutors acknowledged that new DNA testing didn't implicate Lapointe and they didn't have the evidence to go forward with a new trial.

Superior Court Judge Joan Alexander then dismissed the case and told the 69-year-old Lapointe he was free to go.

She also apologized to the family of victim Bernice Martin, saying the justice system had failed them.
