COLUMBUS, Ohio (AP) — Lawyers for Ohio's only condemned female killer have asked the U.S. Supreme Court to accept her appeal.

Death row inmate Donna Roberts was convicted of planning her ex-husband's 2001 killing with a boyfriend in hopes of collecting insurance money.

Roberts' death sentence was struck down in the past after the state Supreme Court said a prosecutor improperly helped prepare a sentencing motion in her case.

The court also said a judge hadn't fully considered factors that could argue against a death sentence.

Earlier this year, the Ohio Supreme Court once again upheld the death sentence for the 73-year-old Roberts.

The state is expected to oppose Roberts' request.

The boyfriend, Nathaniel Jackson, also was sentenced to death in the 2001 slaying.
