Weird news - Finally found remains of man 27 years after disappearing - in a chimney

Sometimes one comes across a whodunit that can defy comprehension. You find a body after so long and no more know who it was, and given the position in which it was found, it will take a large amount of police work just to find out who the person who died was; forget about being able to find out why the person died, and even more important, if the death was not natural, who was the person behind the death. Consider this case, where a person was found dead in the chimney of a bank in Louisiana. The body was only found when the bank decided to do some renovation on the second floor of the building, the floor having been used only for storage space till now. Consider the shock to the people actually doing the renovation when they discover that there are the remains of a person in the place that is being renovated; everything needs to stop while the police is called. Also consider the feeling of employees who suddenly learnt that somebody probably died a very miserable death, dying after being a few days in the chimney.
And then DNA records find the identity of the person, and the family learns that the person who has been missing for 27 years had actually died soon after disappearing, being in the chimney of the local bank. What does the police do in such a case, and can they even suspect that this was a homicide ? (link to article):

The remains of Joseph Schexnider, lost for 27 years, were finally discovered lodged in a brick chimney in the Abbeville National Bank in Louisiana.
