Forgive me for not knowing ( I've been away from things due to serious illness).. but isn't Sunbury about 10 miles from the Lewisville Susquehanna bridge?
Is there any good reason to think this finding of what seems to be some sort of decomposed remains in a steel drum might be related to Mr. Gricar's disappearance?
BTW, not sure if this is still true, but the article said that " material from the drum" hac been sent to a specialist in TN. This makes me think the specialist might be associated with " The Body Farm" which specializes in human decomposition in different conditions.
Also, for those who don't know about Dr. Lee, also working on the case in the news link, Dr. Henry Lee is a renowned forensic pathologist. He is probably best known on Websleuths ( or at least for the longest period of time) for his dramatic conclusions regarding the JonBenet Ramsey murder.
