SAC CITY, Iowa — The skeletal remains found buried in the basement of a Sac City home are those of a man last seen three years ago.
Sac City Police Chief John Thomsen says the state medical examiner's office used dental records to confirm the identity as Mark Koster. He was listed as a missing person in 2010. His family reported he was last seen in May 2009.
Koster who was 58, was the prior owner of the home and had been living with an unknown man about three months before he disappeared. Police are investigating the death.
No one had lived in the house after Koster disappeared and family members sold the house in May.
The new homeowner was remodeling the basement and found the buried remains.
