Barrelling Along

Is this Stacy Peterson disappearance mystery about to break? The Trib says:

After allegedly helping Drew Peterson haul a large container that was warm to the touch from a bedroom, a male relative of the former Bolingbrook police sergeant told a friend Oct. 28 that he was afraid he had just helped Peterson dispose of the body of his wife, Stacy Peterson, a source close to the investigation said.

But the Sun-Times says:

Prosecutors have not called Morphey to testify before a grand jury examining the 23-year-old woman's disappearance because he has "memory lapses" about loading the barrel into Peterson's GMC Yukon Denali, the source said.

This story just won't let up.

Are these spotty, mysterious memory lapses,
A knotty problem with the man's synapses?

Or is one sometimes better off forgetting -
Avoiding confessing to aiding and abetting?
