After more than five weeks of tests and investigation, a medical examiner said Wednesday she was unable to determine how a pregnant woman was killed.

Jessie Davis, 26, was killed in her home near North Canton on June 14, authorities have said. Her body, still carrying a nearly full-term fetus, was found nine days later about 25 miles away in a remote area of a park.

Summit County Medical Examiner Lisa Kohler ruled that the manner of death was a homicide but offered no other details in a news release.

"Based on our examination of the remains, as well as consideration of supplemental laboratory testing and investigative findings, her cause of death will be listed as unspecified homicidal violence," Kohler said.

Investigators previously stated that the advanced decomposition of the body would make determining a cause difficult.

The medical examiner's office said its ruling was final and that it could not exclude any type of injury as causing Davis' death.

Messages seeking comment were left with Kohler. Investigator Joe Orlando said no other information would be released.

Canton police officer Bobby Cutts Jr. has been charged with two counts of murder in the deaths of Davis and her unborn child.

Cutts is the father of Davis' 2 1/2-year-old son, Blake, and her family says he was the father of the baby girl who was due to be delivered July 3.

The 30-year-old Cutts is being held on a $5 million bond. His case has been bound over to a Stark County grand jury.

Myisha Ferrell, Cutts' former high school classmate, has been charged with obstruction of justice. Prosecutors accuse her of helping dispose of Davis' body.

Davis was reported missing when her mother went to her home and found Blake in a dirty diaper, the bedroom furniture toppled and a pool of bleach on the floor.

Blake provided authorities with the first clues, saying: "Mommy was crying. Mommy broke the table. Mommy's in rug."
