Flooding Death Toll From Extreme Weather in Texas And Oklahoma Rises to 17

The death toll from extreme weather in Texas and Oklahoma has risen to 17 after a man's body was found in the Brays Bayou area in Houston. Meanwhile, the search went on for at least 11 people who were still missing in Hays County, including a group that disappeared after a vacation home was swept down the river and slammed into a bridge. Flood waters are slowly starting to recede this afternoon in Houston, where a record-setting four inches of rain in just a few short hours wreaked havoc and led to at least three deaths. Interstate highways in the nation's fourth-largest city turned to raging rivers, neighborhoods became lakes and hundreds of people had to be rescued from flooded homes and stranded vehicles. The flooding had one other horrifying consequence - snakes and other creatures that were flooded out of their homes crept into homes and vehicles in search of high ground.

A casket with human remains inside was found on a hiking trail in Houston on Tuesday and police say the storm waters may have torn the coffin right from its grave.

Walter Rubio got quite a fright when he saw the casket as he was biking in Keegan's Bayou early on Tuesday morning.

'I was on my bike and when I came, I seen the casket and I got a little scared so I had to go to the main street and get the cops,' Rubio told ABC.

Click 2 Houston reports that after unsuccessfully trying to move the casket he called the police, and a woman's body was found inside. A medical examiner is trying to confirm the woman's identity.

Police believe the casket was ripped out of the nearby Riceville Cemetery, where some people have been buried since 1989, and was then carried 100 yards to the bike trail.

'It's disheartening when you have a situation like this,' Deacon Reginald Fields said. 'Nobody wants to come eight years later to re-live someone's death.'

The storm also left hundreds of basketball fans trapped in the Toyota Center for up to six hours after the Houston Rockets-Golden State Warriors Eastern Conference Finals game Monday when the National Weather Service declared a flash flood emergency and an announcer asked fans not to leave because of severe weather. Rockets star Dwight Howard stayed with fans into the night and helped to entertain them.

Eight of those who are still missing are from one vacation house in Wimberley that was washed off its foundation and smashed into a bridge Sunday night. Five adults and three young children from two different families are assumed dead.

One mother made one final, frantic phone call as her vacation home was being swept away by flash flood waters on the Blanco River on Sunday night.

'I'm in a house. I'm floating down the river. Tell mom and dad. I love you, and pray,' 33-year-old Laura McComb told her sister, according to KXAN-TV.

Mrs McComb and her two children Andrew, 6, and Leighton, 4, are among the people still missing following flash floods near the popular vacation spot of Wimberley over Memorial Day weekend. (Dailymail)
