Kenny Grobe seems to be bragging!

Look at this exert from a KFVS TV-12 news article from 5-05. Kenny Grobe seems to be bragging, doesn’t he?
Because there are no arrests yet in this investigation, Butler County Investigator, Jim Akers can't tell us the exact evidence, that leads him to believe foul play caused 74 year old Mary Lee Grobe's disappearance, but he certainly told us why his crews will continue working until this sewage pond is completely drained. "Her house being several yards from her, if foul play was involved, you're going to need to dispose of her quickly,” said Akers.
Akers narrowed a list of possible suspects down to one unnamed person, and once this pond is empty, he hopes he'll have more evidence in the case. "If we find nothing there, then we're going to go to the next most logical place," said Akers.
While these investigators continue working, some members of Mary Lee's family continue a much different search of their own. "I have no reason to believe my mother is dead. I do not believe that, until someone shows me my mother is dead, I'm not going to believe that. I can't think of any reason or any family member who has reason to harm my mother," said Ken Grobe, Mary Lee Grobe’s son.
