A woman whose body was found partially submerged Monday in the Mississippi River had been strangled, Davenport police said Tuesday.

Yvonne (Bonnie) E. Nicholson, 32, of Rock Island, was identified using fingerprints on file in Rock Island County, Capt. David Struckman said.

Nicholson's body was taken to Rockford, Ill., for an autopsy Tuesday, one day after two men spotted her body five feet from the tree-lined shore along South Concord Street on Davenport's west side.

Nicholson was found wearing a sweatshirt, shorts and socks when she was found about 9:30 a.m. Monday.

Her death is classified as a homicide, Struckman said. Investigators are interviewing possible witnesses and canvassing areas where she may have been before her death.

Anyone with information about Nicholson or her whereabouts throughout the weekend is asked to call (563) 326-7979.

The only information police had when the woman was removed from the river was that she was black, between 18 and 30 years old, between 5 feet 2 inches and 5 feet 4 inches tall and weighed between 150 and 185 pounds.

They believe her body had been in the river for a short amount of time.

Nicholson's record in Rock Island County includes forgery and drug charges. In January 1996, she pleaded guilty to a charge of unlawful possession of a controlled substance and she pleaded guilty in August 1998 to a charge of forgery.

She was placed on two years' probation for both convictions but failed to maintain her probation status. After revoking her probation, a Rock Island County Circuit judge sentenced her in November 1999 to three years and six months in the Illinois Department of Corrections.
