The Feb. 6 retrial for murder defendant Stanley Liggins has been postponed again in Scott County District Court.

The three-week murder trial now will begin May 22, according to an order filed Sept. 15 by Chief District Judge Marlita Greve.

Motion hearings that were scheduled to begin Tuesday also were postponed until Feb. 20, according to Greve’s order.

Greve said in her order that she granted a defense request to postpone the trial and motion hearing dates "in the interests of justice."

Liggins, 54, is charged with first-degree murder, willful injury causing serious injury, first-degree sexual abuse, first-degree kidnapping and first-degree arson.

Prosecutors say Liggins strangled Jennifer Ann Lewis, 9, of Rock Island, and burned her remains on a Davenport school playground in 1990.

Liggins was tried twice in the girl's death in the 1990s, once in Scott County and the second in Dubuque after he was granted a change of venue.

He was convicted in both trials and sentenced to life in prison. The Iowa Supreme Court overturned the first conviction on a technicality. On Nov. 6, 2013, the Iowa Court of Appeals reversed the second conviction, and the Supreme Court decided not to hear the case.
