Myrtle Beach police say they are investigating what happened at the hotel but no charges were filed. Phone numbers for Wilkerson's husband were disconnected.
Harrell told the dispatcher that Wilkerson was "talking about Jesus and how there are demons in my house and how I'm trying to control her but I'm trying to keep them safe."
Harrell said she had taken Wilkerson's car keys away but her sister had found another set and driven off with the children.
After the call to dispatch, Daytona Beach officers stopped Wilkerson's black Honda Odyssey and she expressed fear that her husband would be coming to Florida to harm her and her children.
The children were sitting quietly, smiling, and showed no signs of distress, the police report said.
"It was clear during my conversation that Wilkerson was suffering from some form of mental illness, but she was lucid," the Daytona Beach police officer said in the report.
