TURTLETOWN, Tenn. (AP) -- Polk County authorities are investigating what an incident report describes as vandalism.

The couple who live in the mobile home where a cinder block crashed through a window say a note taped to it contained a racial slur and threatened their lives.

Ellis Weatherspoon says he and his 3-year-old son were in the kitchen around midnight on June 13 when the block crashed through a window near them. They were not hurt.

Weatherspoon is black. He lives with Jennifer Weatherspoon who is white and the couple consider themselves married, according to the Chattanooga Times Free Press.

Polk County Sheriff Bill Davis says evidence has been sent to a crime lab and results should be back in about a week.
