3 dead, 2 missing as severe weather slams Oklahoma

Three people are dead and two others are missing after severe weather slammed Oklahoma over the weekend.

Several Oklahoma agencies, including the Tulsa County Sheriff's Office and the Wagoner County Sheriff's Office, are conducting a search for two people, one of them being a child, after their vehicle was swept away in flooded waters on Sunday.

The incident occurred along Oklahoma Highway 64, south of Leonard.

Authorities said two others who were riding in the same vehicle have been rescued.

Among those killed over the weekend, one person was found dead after a tornado swept through Spaulding, Oklahoma, on Saturday night, according to Hughes County Emergency Management.

"Two homes were destroyed and several small structures along with many trees suffered damage," HCEM said in a post on social media on Sunday. "There were two injuries including one fatality."

Two others died when their vehicle was swept off the road due to flooding caused by the heavy rainfall in Moore, Oklahoma, police said.

Following a search, the bodies of two people -- an adult female and a 12-year-old child -- were found outside one of two vehicles that were swept away, Moore Police spokesperson Clint Byley told ABC News early Sunday.

Moore Police Department reported conducting a "swift water rescue involving two vehicles stranded in flood waters" in the early hours of Sunday.

"One of them left the roadway and was swept under the bridge. At the time of the incident all but two occupants were rescued," officials wrote in a post on Facebook. "It is with great sadness that we report that two individuals, an adult female and a 12-year-old male, were later located deceased."

Both vehicles were submerged in the water after being washed off a bridge, police said.

More than 30 million Americans were on alert for severe weather over Easter weekend.

Several states in the Heartland had already been slammed with tornadoes, hail and damaging winds.

"This was a historical weather event that impacted roads and caused dozens of high-water incidents across the city," the Moore Police Department said on social media. "We would like to extend a thank you to our neighboring agencies who assisted in rescue efforts. Our thoughts and prayers go out to the family and friends of the victims."

Officials had earlier said they were working to assist "more than a dozen" motorists whose vehicles were stuck in high water.

"Multiple roads and neighborhoods have water over the curbs," the department said on social media late on Saturday. "Stay home if at all possible."
