WASHINGTON (AP) — A judge promised more openness Tuesday after months of confidential post-trial proceedings in the case of murdered Washington intern Chandra Levy, disclosing for the first time why a key prosecution witness could be discredited.

Prosecutors and defense attorneys were in court again Tuesday for a hearing in the case of Ingmar Guandique, who was convicted of Levy's death and sentenced to 60 years in prison. Defense attorneys have said they intend to request a new trial for Guandique based on the information about the prosecution witness.

NEW YORK (AP) — Microsoft is the last of the three big video game console makers to unveil its latest gaming system. Tuesday's unveiling comes nearly eight years after the Xbox 360 went on sale. It follows last fall's debut of Nintendo's Wii U and a preview in February of the upcoming PlayStation 4 from Sony.

Each machine has a set of features designed to draw gamers away from rival consoles. There's one thing all three have in common, though: They are about more than gaming and include entertainment services such as television, movies and music.

DES MOINES, Iowa (AP) — A massive search is underway for a 15-year-old girl who was abducted yesterday from an Iowa bus stop.

Authorities say the man who is suspected of taking her and another girl has been found dead.

Dozens of federal, state and local authorities are searching by air, land and water for Kathlynn Shepard. She and a 12-year-old girl were taken from a bus stop yesterday afternoon after accepting a ride from a stranger. The younger girl was able to escape.

PORTLAND, Ore. (AP) — The final ballots are getting dropped off Tuesday in Oregon as Portlanders decide for the first time in more than 30 years whether to add fluoride to their drinking water.

If voters say no, Portland will remain the largest U.S. city yet to approve fluoridation to combat tooth decay.

Voters in Portland twice rejected fluoridation before approving it in 1978. That plan was overturned two years later, before any fluoride was ever added to the water.
