OKLAHOMA CITY (AP) - Oklahoma House Speaker Kris Steele has named a task force to study the Department of Human Services.

Steele said Wednesday the task force will look at ways the agency can better serve children in the state.

The move comes after the deaths of some children who were returned to their families after being in DHS custody.

The deaths include a girl who was returned to her father even though she was injured earlier while in his care. Another girl who died was allowed to remain with her mother even though the child and mother both tested positive for illegal drugs when the girl was born.

The task force's chairman is Republican Rep. Jason Nelson and Republicans Pam Peterson and Pat Ownbey and Democrats Rebecca Hamilton and Wade Rousselot are members.
