ORIGINAL STORY
Two people have been arrested and police are looking for a third person, in the death investigation of 41-year-old Rob Kohn. Kohn's body was found early Saturday morning in a farm field along Utah Avenue, just South of Telegraph Road in Davenport. Police arrested 20-year-old Jessica Loerzel of Davenport and 20-year-old Barry Hamilton of Chicago, in Chicago on Monday.
They have been charged with first degree murder and willful injury. Police say they confessed to the murder and are waiting to be brought back to Scott County. However, police say the third person, 21-year-old Darius Johnson, is also involved and is still on the loose. They believe he is still in the Chicago area.
Investigators say those three took Kohn out to a farm field and shot him in the head early Thursday morning. They say the suspects knew each other, but did not know Kohn, until sometime after the December fourth. That's when Kohn was released from the Scott County jail. He was in there for third public intoxication offense.
Police say this case was very tough to crack for several reasons. One is because Kohn was homeless. Another is because his body was accidentally run over by a drunk driver on Saturday, the day he was found. Police say they were able to piece things together by talking with local homeless shelters and people on the streets.
From their detective work they were able to get a description of a car the suspects could have been driving to Chicago. They alerted the Chicago police department to look for it and it was spotted. Detectives traveled there and made the arrests. Police believe they know a motive, but are not releasing it at this time.
