Columbus police are looking for a man who is now charged with his roommate's murder.
The Columbus Dispatch reports that Quentin Robertson, 40, has been charged.
Robertson allegedly stabbed Michael Freeman at their Holton Avenue home.
Freeman's decomposing body was discovered by a maintenance man last week.
Robertson has been missing for weeks, according to neighbors.
A third roommate was still living in the home when the body was found. He told police he did not know where either of the men were located.
Robertson, who remains at large, is a convicted sex offender who was released from prison in August 2011 after serving 15 years for attempted rape, reported the Dispatch.
