However, Davenport police need for the complete results from the examination and the toxicology reports of Agnes McFedries Kennedy, of Davenport, before they release the cause of death, according to police Capt. David Struckman.

Police released no other information Thursday about the homicide.

A couple returning home around 8:30 p.m. Saturday found Ms. Kennedy's body in an alley along the 1800 block of West 7th Street. Ms. Kennedy was taken to Davenport's Genesis Medical Center, West Campus, where she was pronounced dead.

Her death was investigated as a homicide from the beginning because of its suspicious nature and many unanswered questions.

In February 2005, Ms. Kennedy described her life as a prostitute to a reporter with The Dispatch and The Rock Island Argus. She began selling herself for money at age 26 and lead her into a life of uncertainties and sometimes violence from customers.

Police have yet to say if her chosen profession had anything to do with her death.

Earlier this year, another prostitute, Angela Marie Hennes, 41, was killed.

Scott County Sheriff's Maj. Mike Brown said investigators believe Ms. Hennes' prostituting had "a strong connection" to her death.

Her badly burned body was found in an isolated farm field in the 15000 block of 100th Avenue on Jan. 13. She had been strangled. Her death remains unsolved, with a $5,000 reward being offered for information in the case.

Authorities have said they don't believe the two cases are related.

Anyone with information in either case is urged to call the Davenport Police Department at (563) 326-7979, the Scott County Sheriff's Office at (563) 326-8628, or Crime Stoppers of the Quad Cities at (309) 762-9500.
