Authorities suspect the fire that destroyed the historic Tink Larson Field was intentionally set. The state fire marshal has ruled out other causes of the April 6 fire, including electrical or lightning, Waseca police Capt. Kris Markeson said Monday.
Earlier this month, authorities asked a man seen at the field the night of the fire to come forward, but police have since talked with him and determined he is not a suspect, Markeson said. The Minnesota Chapter of the International Association of Arson Investigators is offering a reward up to $5,000 for information leading to the arrest and conviction of the person believed to be responsible through the Minnesota Arson Reward Project.
