Usually the state agency Child Protective Services appears in news articles as investigators of child abuse.
But police in Abilene say they've executed search warrants at the local CPS office and a supervisor's home and car.
The Associated Press reported Tuesday that the police searches come after the death of a 22-month-old girl whose mother claimed her military husband's deployment overseas left her too stressed to care for their three children.
Abilene Police Chief Stan Standridge said police began a rare investigation of CPS after "a refusal of certain CPS supervisors to cooperate" with officers looking into the death of Tamryn Klapheke.
Agency spokesman Patrick Crimmins said a caseworker assigned to investigate allegations of medical neglect against Tiffany Nicole Klapheke closed the case soon after being promoted to supervisor. In doing so, she violated agency guidelines that require a final face-to-face visit, he said.
