Actor Bryan Cranston, who plays a good man turned bad on “Breaking Bad,” told David Letterman he was once suspected of murder.

Cranston told this rollicking tale on Letterman’s “Late Show” Friday night on CBS. Apparently, the incident happened when Cranston was very young — in the 1970s — and traveling around the country on motorcycles with his brother, picking up odd jobs for food-and-gas money along the way.

Let us emphasize before we get any further that Cranston was never a serious suspect in the murder of a Daytona Beach restaurant chef who was openly and universally loathed by the joint’s waiters and busboys — including, for a time, the Cranston brothers.

But the reason why the two drew the attention of police was that the chef, who Cranston said was named Peter Wong, happened to go missing and then turned up dead at around the same time that the Cranstons quit the restaurant and headed north on their motorcycles.

Cranston proved to be an adept storyteller on the Letterman show, where he was appearing to promote the season finale of “Breaking Bad” airing this Sunday night on AMC at 10/9c.
