SAC CITY - Police are continuing to investigate the discovery of human remains Monday in the basement of a Sac City home.
Sac County Attorney Ben Smith said because the investigation is ongoing, he's unable to comment on it.
Smith also declined to comment on whether investigators are looking at the possibility this discovery is related to the disappearance of Mark Koster, who was reported missing to Sac City police on July 4, 2009.
