VICKSBURG, Miss. (AP) _ Lawmen admit they are stumped over the disappearance of furniture store heiress Jacqueline Levitz.

The 62-year-old woman was reported missing in Nov. 20 from her home overlooking the Mississippi River. Authorities found blood on a bed in her home and evidence of a struggle.

``We haven't come up with anything,'' said interim Warren County Sheriff Otho Jones. ``It's not on the back burner, it's just on hold until the FBI gives us their findings. Right now, the ball is kind of on the FBI's court.''

Special Agent Hal Nielson, spokesman for the FBI in Jackson, said agents in Florida and California, where Levitz maintained houses, are still working on the case, and the FBI laboratory is analyzing evidence taken from Levitz's home in Vicksburg.

Levitz's family has offered a reward of $100,000.

Jones said the failure to find a body, a suspect or a motive has led lawmen to believe Levitz, whose late husband was co-founder of the Levitz furniture store chain, is dead.
