SAC CITY, Iowa (AP) – Sac City police say human remains discovered in the basement of a recently purchased house could be those of the previous homeowner who disappeared in 2009. Police Chief John Thomsen says “all signs point” to Mark Koster.
He was last seen with a friend on July 4, 2009. He was 58. The remains were found on Monday by the new homeowner, who was remodeling the basement.
Police searched the house in 2009. Thomsen says there was no indication of foul play, and it appeared Koster left. He was declared legally dead in October 2011. No one lived in the house after Koster disappeared. Family members sold the house in May.
