Suspect Linked To Webster Groves Killing By RALPH WILLIAMS Of the Post-Dispatch Staff A fingerprint of the man charged with murdering Mrs. Agnes Greenwell in Maplewood has been matched to one found on the automobile of a 17-year-old girl killed in Webster Groves last July, St. Louis County police say. In addition, police are investigating possible connections between Kevin James Kiger, the accused murderer, and a 16-year-old girl killed in June in west St. Louis County. Kiger, 23, is being held in City Jail. Detective Michael J. Fitzpatrick of the county police has identified a fingerprint found on the passenger-side window of Mary Katherine Laforest's car as that of Kiger's left little finger. Miss Laforest's body was found July 19 in a bird sanctuary near Blackburn Park in Webster Groves. The Richmond Heights girl had been strangled. The fingerprint was found shortly after she was killed, but was not identified until checked against Kiger's fingerprints, police said. Webster Groves detectives are trying to find out whether Miss Laforest knew Kiger. Kiger was charged Friday with capital murder in the killing of Mrs. Greenwell, 50, whose body was found last Tuesday in her daughter's home in Maplewood. Her throat had been slashed. A straight razor taken from the home was found later by police. Kiger was arrested early Tuesday by St. Louis police on suspicion of carrying a concealed .pistol and drugs. When police recovered the razor that an informer said Kiger had dropped just before his arrest, he was charged with the murder. Police noted that the circumstances of Miss Laforest's killing were similar to those in the June 5 killing of Velda Joy Rumfelt, a Brentwood girl whose body was found in a wooded area off AUenton Road near Six Flags amusement park. Miss Rumfelt had been strangled, and both she and Miss Laforest were high school students living in the south-central part of the county. I -i Kiger, an unemployed carpenter, told police he lived in the 7400 block of Hardscrapple Drive, Marlborough, and had been free on bond on burglary and stealing charges. He has refused to make a statement. :?
