Lapalla said that the murderer is probably not a "Dr. Jekyll and Mr. Hyde" and that he could be leading a normal life, appearing to be a good citizen. He also said that the killer probably is not a veteran, because if he had served in the armed forces for even a year, his maniacal tendencies would be apparent. He stated that the murderer was not necessarily a resident of the area, despite his knowledge of it. He said that all the attacks show evidence of cool and cunning planning. He further said that the strengthening of the police force would not scare the killer away, but that he would willingly leave due to the difficulty of committing a crime. "This man is extremely dangerous. He works alone and no one knows what he is doing because he tells no one," Lapalla said, adding that the killer may have reasoned in past crimes that the only way to remain unidentified is to kill all persons at the scene. Lapalla did not believe the killer was a black man because "in general, negro criminals are not that clever."
