For two nights in a row we came home to find pool water tracked into the house, on the brown carpet near the sliding glass door leading out to the back porch.
We quietly and carefully searched each room but found no other traces of intruders.
On the third night, the sliding glass door was left open, and searching an upstairs bedroom revealed that the intruders had barricaded the door from the inside with mattresses, trapping themselves inside.
They turned out to te the next door neighbors kids.
