The doll was found in the area of University Avenue East and the Highway 85 South overpass on Oct. 4 around 9:50 p.m. Police say the doll had racist and sexist messages written on it.

Officials describe the suspect as a man between 30 and 40 years old with an average build. An older model Toyota vehicle was seen nearby.
