CARIBOU (AP) – Two FBI profilers on Friday visited key sites in the investigation into the arsenic-tainted coffee that killed one man and hospitalized another 15 churchgoers.

The federal investigators came to New Sweden as state police said their criminal probe into the April 27 incident appears unlikely to soon produce a major break.

The FBI profilers visited Gustaf Adolph Lutheran Church and the nearby farmhouse of Daniel Bondeson, who committed suicide five days after the poisonings. Police believe Bondeson had a role in the homicide, but they haven’t determined whether he acted alone.

Detectives hope the FBI agents will be able to shed light on Bondeson’s mental state and the psychology of the crime, which police believe may have been sparked by an internal church dispute.

Lt. Dennis Appleton said Friday’s news briefing in Caribou would be the last regularly scheduled meeting with reporters.

State police have been holding daily news conferences on the high-profile case for over a week.
