An accused murderer appeared in a Cleveland courtroom Wednesday morning.

Ronald Hillman pleaded not guilty to unrelated charges of failure to meet with a probation officer and register as a sex offender. Bond was set at $40,000 for those charges.

Hillman is accused of murdering his co-worker Michaela Diemer and dumping her body on the city's west side.

Hillman is being held on a $3 million bond on aggravated murder charges in connection with Diemer's death.

Cleveland Police say Hillman lured his victim into an empty house and killed her. Her body was found on Train Avenue early Wednesday, Sept. 24.

On Friday, Sept. 26, the Cuyahoga County Medical Examiner's Office positively identified the deceased woman as 31-year-old Michaela Joy Diemer, of Streetsboro.

Tuesday, Sept. 24, Hillman was driving Diemer's car and allegedly drove the car to Minutemen Staffing where they both worked.

Diemer's dad, Andrew, said his daughter had been living in California for four years. She moved back home in early August and was working at several part-time jobs.

Diemer was last seen near the Cleveland Metroparks Zoo on August 20.

Mr. Diemer filed a missing persons report on Aug. 24 after contact was lost with her.

He told police that on Aug. 14, he told Michaela she could no longer live at his home, so she left for a women's shelter.

The last time he spoke with her on Aug. 20, she said she was by the Cleveland Zoo. Additional calls made to her phone went straight to voicemail.

The Cuyahoga County Medical Examiner has not yet released the cause of death.
