Rumblings of a Richard Gaikowski connection surfaced due to his familiarity with Albany, having worked for the Knickerbocker News from 1966 to the latter part of 1968, before traveling to Europe and then returning to America, relocating in Haight-Ashbury in San Francisco. However, there were notable crimes in the months and years surrounding the August 10th 1973 timeline, relative to the Albany Medical Center.
The first was the murder of prostitute Gloria South (18), shot once behind her left ear with a .25 caliber pistol. Her body was found close to Morris and Lark Street, behind the Veterans Hospital. But this murder was committed approximately two years prior to the Albany letter on June 29th 1971, despite the location being very close to the Albany Medical Center. Investigators had a prime suspect in this case, but without any solid evidence tying him to the crime they were unable to make good on their suspicions.
The second was a lot closer to the timeline, occurring four-and-a-half months after the said date of August 10th 1973, on December 27th 1973, when Barbara Smith (24) of Hamilton Street was murdered close to the St Philips Day Care Center on Road Street. The perpetrator had shot the young woman in the head, although it had failed to penetrate her skull. He had then used a rock to inflict the severe injuries noted at autopsy. This location was also close to the other murder, along with the Albany Medical Center.
These murders occurred from June 1971 to November 1974. The Zodiac's hiatus in confirmed correspondence occurred between the March 13th 1971 Los Angeles letter (or the questionable March 22nd 1971 Pines card) and January 29th 1974, with his last confirmed mailing to the San Francisco Chronicle newspaper, in the form of an Exorcist letter. Is it possible the Zodiac switched from one location to another during this timeline, or is it more likely that the Zodiac Killer is simply being credited for crimes far and wide, with little other than letters as evidence? Many researchers question the nature of certain crimes having been committed by the Zodiac Killer, despite the fact he did once claim in the November 9th 1969 Bus Bomb letter that he would "change the way the collecting of slaves. I shall no longer announce to anyone. When I committ my murders, they shall look like routine robberies, killings of anger, + a few fake accidents, etc".
The letter found in in Doreen Gaul's belongings read: "SO YOU THINK YOU CAN FOOL THE OLD KILLER HA HA. I KNOW ALL YOUR MOVEMENTS AND THE TIME THEY ARE MADE. TIME IS SHORT, ENJOY LIFE WHILE YOU CAN. YOU ARE TO BEAUTIFUL TO LIVE AND I MUST KILL YOU. THE ZODIAC KILLER".
