A man that went missing several years ago, was finally found when a man was renovating his home, according to police reports.

A man renovating his home in Sac City, Iowa, found what appeared to be human remains in his basement. He immediately called police. Authorities arrived at the scene and confirmed his suspicions.

"The skeleton was found buried in a very accessible place in the basement," Sac City Police Chief John Thomsen said. "There are suspicious circumstances to this find just by the way that the remains were found."

The remains were sent to the Office of the Medical Examiner of the State of Iowa for autopsy, according to police. Dental records positively identified the remains as those of Mark Koster.

Koster, 58, disappeared on July 4, 2009. His disappearance was investigated at the time and a search warrant that was executed at the home showed signs of foul play. He was declared legally dead at the request of his family in 2010.

According to reports, there was an unidentified male companion living with him for about three months before his disappearance, Thomsen said. The neighbors knew the man, but did not know his name. The case is being investigated.
