Three people are dead after a severe storm blew through southeastern Missouri.

Scott County Sheriff Rick Walter says damage assessments are underway in Diehlstadt, Missouri, where a man and his two adult sons were killed.

Walter says they are not releasing the names of the victims until their families can be notified.

Walter tells reporters several homes were damaged in the storm Monday night, especially on and near Highway 77. One home had its roof torn off by high winds.

Walter says the mobile home where the three people were killed was blown away.

Scott County was under a tornado warning around 9 p.m., but it is not yet known if a tornado caused the damage.
