HUDSON, N.Y. (NEWS10) – New York State Police say they arrested three men on arson charges following a several year investigation.

Two of the men, police say were volunteer firefighters at the time.

Police say they began their investigation following car fire in the town of Kinderhook. The cause of the fire was determined to be arson.

While investigating that incident, police say the Columbia County Fire Coordinator’s Office, Columbia County Cause and Origin Team, and the Dutchess County District Attorney’s Office, and State Police uncovered several other criminal acts that occurred over the past four years.

Police say Lucas Briggs, 23, of Hudson, Tanner Rivenburgh, 20, of Stottville, and Ryan Hogencamp, 32 of Kinderhook, are connected to an arson fire set to a barn on CR-21 in April 2014, an arson vehicle fire in October 2012 on Kinder Drive, and the false report of an emergency incident on the Hudson River near the Stuyvesant Boat launch.

On May 7, 2015, Briggs and Rivenburgh were arrested and charged with 3rd degree arson.

On July 28, 2016, State Police say a Columbia County Grand Jury handed up an 11 count indictment against Hogencamp for his involvement in the crimes.

Hogencamp is charged with 3rd degree arson, two counts of 3rd degree insurance fraud, three counts of 1st degree falsifying business records, two counts of false written statement, and falsely reporting an incident.

Hogencamp was arraigned and remanded to Columbia County Jail in lieu of $35,000 cash or $70,000 bail.
