MOORE, Okla. - Emergency crews searched the broken remnants of an Oklahoma City suburb Tuesday for survivors of a massive tornado that flattened homes and demolished an elementary school.

As the sun rose over the shattered community of Moore, the state medical examiner's office cut the estimated death toll by more than half but warned that the number was likely to climb again.

Gov. Mary Fallin said an untold number of people were still missing.

The massive tornado that ripped through a handful of Oklahoma City suburbs and killed at least 50 people grabbed the attention of the sports world on Monday, especially the players and coaches with ties to the area.

Kevin Durant, a three-time scoring champion for the NBA's Oklahoma City Thunder, posted on his Twitter account that he was praying for everyone involved.

Mets pitcher Jeremy Hefner went to Plaza Towers Elementary School in Moore, just south of Oklahoma City.
