An Ohio man has been charged with murder in connection with his wife's death after initially claiming she died by suicide, according to police.

Kyle Long was arrested following a four-month investigation into the death of his wife, who was found with 17 stab wounds. Long had originally told authorities that his wife had stabbed herself to death after telling him she wanted to separate from their marriage.

Police did not immediately release details about what evidence led investigators to conclude the death was a homicide rather than a suicide. The investigation spanned four months before charges were filed against Long.

The case highlights the challenges law enforcement faces when investigating deaths that are initially reported as suicides but may involve foul play. Multiple stab wounds can raise questions for investigators, as such injuries are considered unusual in suicide cases.

Long is now facing murder charges in connection with his wife's death. Additional details about the investigation and the evidence that led to the charges have not been made public.
