Federal prosecutors have asked a judge to set a June 27 hearing to consider whether the suspect in the Tucson shooting rampage is mentally fit to stand trial.

Jared Lee Loughner is being treated at a Missouri prison facility where he has been forcibly medicated for about 10 months in a bid to try to make him mentally fit.

Loughner has pleaded not guilty to 49 charges stemming from the January 2011 shooting that killed six people and wounded former U.S. Rep. Gabrielle Giffords and 12 others.

U.S. District Judge Larry Burns had ruled in the past that Loughner isn't psychologically fit to stand trial, but believed Loughner can eventually be made ready for trial after more treatment.

Loughner's stay in Missouri is set to end June 7. The report by Loughner's psychologist isn't expected to be publicly released.
