The father of a Kasota man killed on Monday says the family is planning to take legal action against a sheriff's deputy who fired the fatal shots. Tyler Heilman's father, Mark, says his 24-year old son was shot at least three times, although he was unarmed. A spokesman for the Bureau of Criminal Apprehension says plainclothes LeSueur County deputy Todd Waldron was working on another case when he saw Heilman speeding and driving erratically. Mark Heilman said witnesses told him the two struggled briefly in a parking lot.
