A New Iberia man faces up to 25 years in prison and more than $1 million in fines after pleading guilty in federal court to five counts of mailing threatening letters to Gov. John Bel Edwards, two parish courthouses and four South Louisiana post offices in late 2015 and early 2016. Thirty-three year old Kyle Dore will be sentenced June 9, according to acting U.S. Attorney Alexander C. Van Hook.

According to Van Hook, nine of the four letters threatening agencies or persons employed by those agencies also contained a white powder — the implication, according to Van Hook, was that the substance was toxic — that proved to be harmless.

Dore was indicted in February of last year. He faces five years in prison and a $250,000 fine on each count. The case was investigated by the FBI, Louisiana State Police and the U.S. Postal Inspection Service.

KATC reported on Dore’s history of run-ins with the law shortly after he was indicted last year. Read more about that here.
