A third handwriting expert, Herbert J. Walter, whose credentials included working on the Lindbergh baby kidnapping in 1932, was brought in. After examining documents written by Heirens, Walter declared that Heirens wrote the ransom note and the lipstick scrawl on the wall and attempted to disguise his handwriting. However, this was in direct contradiction from what he said several months before, at which time he said he doubted that the two writings were authored by the same person. He was quoted as saying there were "a few superficial similarities and a great many dissimilarities."
