COLUMBUS, Ohio (AP) - An Ohio coroner says a man suspected of being the third fatal victim of a deadly Craigslist robbery scheme died in August, weeks before the suspected killings of two other victims.
    
The body of Ralph Geiger was discovered Nov. 25 in Noble County in rural southeastern Ohio during an investigation into two other deaths and the wounding of a fourth man.
    
Noble County Coroner Alan Spencer lists Geiger's date of death as around Aug. 9, according to a copy of Geiger's death certificate obtained Tuesday by The Associated Press.
    
Authorities believe the other victims were killed in October and November.
    
Police have identified as suspects a 16-year-old high school student and a 52-year-old self-styled preacher.
