A Florida man has been charged in the 2009 murder of a northwest Iowa man.

The Sac City Police Department says 54-year-old John Green was arrested Tuesday and is charged with first degree murder. Police say he admitted to killing 58-year-old Mark Koster.

Koster was reported missing in 2009 by family. He was declared legally dead in 2011.

Koster’s home was sold in 2012 and that’s when his decomposed body was discovered in the basement.

Investigators say Green lived with Koster for a short time in 2009. When police interviewed him Tuesday, they say he admitted to killing Koster and hiding his body.

Green is awaiting extradition back to Iowa.
