SIOUX FALLS, S.D. (AP) — A Sioux Falls police officer is being credited with helping save members of a family overcome by carbon monoxide gas in their home.

Police Chief Matt Burns says Officer Ryan Chase went "above and beyond the call of duty" by entering the house numerous times at the risk of his own safety to help rescue the family of six.

Michael and Marchelle Holloway and their four children were poisoned by the potentially deadly gas Saturday morning. Michael Holloway was able to get one child outside, and his wife was able to call 911.

Chase is a 17-year veteran of the police force but had never encountered carbon monoxide before. But he says he knew it was a bad situation, and that he needed to get everyone out of the house.
