High and fast waters were hampering search efforts.
“We are doing what we can. We did an extensive search last night to no avail,” Fire Maj. Tammy McKinney said. “As fast as that water is moving it's hard. The water is dictating what we do. Our reports were possibly one adult and three children were swept away by a wall of water while trying to seek shelter from the tornado.”
It's not clear whether the 4-year-old is among the nine people _ two children and seven adults _ whose tornado-related deaths have been confirmed by the state medical examiner's office. The medical examiner has identified four of those victims and is asking for the public's help in identifying the five others.
“If someone is missing a loved one from last night's tornado, we would encourage them to contact our office at 405-239-7141, said Amy Elliott, chief administrative officer for the office.
