Topeka ? Kansas Attorney General Derek Schmidt is asking people to wear blue on Friday to raise awareness of child abuse.

Schmidt notes that April is national Child Abuse Prevention Month.

The attorney general and the state’s Child Death Review Board also are asking Kansans to be aware of clues of possible abuse.

Schmidt’s office says the signs include parents or caregivers who have no social contacts outside their families and who are controlling or resentful of a child. Also, abusers tend to belittle children with criticism or put-downs and avoid talking about a child’s injuries.

Also, the attorney general’s office says black eyes, human bite marks and burns seldom come from everyday play.
