FWIW, I was on nodding acquaintance with Sutcliffe. We often drank in the same pub. He always seemed quiet and unassuming. But dont they always?
His two brothers, however, were well known: one a drug dealer and one a thief.
The dealer never was prosecuted even tho' he dealt openly and ran a Porsche while officially unemployed. It was said the drug squad tipped him off. Retired to a farm he bought.
The thief 'went away' on a regular basis.
The NoW got wind of the drug dealing and spent several weeks in the local trying to buy drugs off the dealer as part of a sting. Typically, they got the wrong brother and could not understand why he was reluctant. We knew who the reporters were, but never let on to them their mistake. Eventually, the thief sold them some pills and was caught and prosecuted. He retired to a block of sheltered housing as their security manager!
Two mates went out with Sutcliffe's two sisters, nothing outrageous to report.
