CARIBOU (AP) – Two investigators from the FBI crime lab in Quantico, Va., were due to arrive by early Friday to help police put together a profile of the arsenic poisonings at a northern Maine church.

The FBI has provided a list of questions for the Maine State Police, who intend to re-interview some witnesses to the April 27 poisonings at the Gustaf Adolph Evangelical Lutheran Church in New Sweden.

One person died and 15 others were sickened after drinking arsenic-laced coffee at a church reception following Sunday services.

State Police Lt. Dennis Appleton told reporters that about 35 church members have filled out questionnaires and submitted fingerprints and DNA samples to police. Most of the rest of the church members were either poisoning victims or their family members.

Appleton said the FBI profilers can help detectives learn more about the psychology of Daniel Bondeson, a parishioner who fatally shot himself five days into the investigation. Police say Bondeson, 53, was at least partially responsible for the poisonings, but have left open the possibility of other suspects.

The profilers can also help investigators learn more about the psychology of the crime itself, Appleton said.

“We’re trying to rule in or out one or more people,” Appleton said. “We’d like to be happy with our final decision and we called them in for help.”

Appleton said detectives have been looking at the inner workings of the church community. He has said that the poisonings may have been triggered by something that might appear trivial to outsiders, but would be important to those within the church.

Some have speculated the poisonings are somehow linked to a communion table that Bondeson and his siblings donated to the church just last month. The table, however, has yet to be used for communion.

Appleton said he doesn’t think it was any one thing that led to the poisonings, but perhaps a series of events that got to be too much for the perpetrator.

“I don’t think this is all about a table,” he said. “I think that’s one of the straws, perhaps, that has been loaded onto the camel’s back.”
