CNN - MeLisa Cleary was 30 years old and a mother of three when her marriage started to fall apart.

She was in the process of separating from her husband, Daniel, when she was last seen on June 6, 2008.

Her body was found three days later near the railroad tracks in Hartsburg, Illinois, a town more than 20 miles away from Mackinaw, where the Clearys lived.

Police said her body showed significant signs of blunt force trauma, particularly to her head and neck. The Logan County Coroner ruled her death a homicide.

The investigation remains open, but police still have not announced any suspects in the case, nor have they made any arrests. They are continuing to work on it "nonstop," said Capt. Bob Henderson of the Tazewell County Sheriff's department.

"If anybody has any pertinent information involving the disappearance and death of MeLisa, by all means give us a call," Henderson said.

The Tazewell County Sheriff's Office can be reached at 309-346-4141. The Logan County Sheriff's Office can be reached at 217-732-2156.
