He’s a painter not a killer!

Sickert was most certainly not the infamous killer.  He may have been a tad bit obsessed with the case, but that doesn’t make him a murderer.  Granted he did paint a few interesting subjects, there is no evidence to really point to Sickert other than a few works of SUBJECTIVE art.  Cornwell’s so called “DNA” tests do not prove anything.  Even if one believes that Sickert wrote a letter or two to the police that doesn’t make him a killer.  It may make him a pathological liar, but it does not prove he killed anyone.  Sickert was an important person during this time and he knew a lot of prominent people.  I feel that someone as well known as Sickert would have been caught if he had attempted to go on a killing spree.
