In the second “Zodiac” letter sent in August 1969, the writer stated that he had used a gun with a light attached to the barrel for shooting at night. This letter offered details regarding the shooting on Lake Herman Road on December 20, 1968, and addressed questions about the killer’s ability to see the victims in the dark.
“Last Christmass. In that epasode the police were wondering as to how I could shoot + hit my victoms in the dark. They did not openly state this, but implied this by saying it was a well lit night + I could see the silowets on the horizon. Bullshit that area is srounded by high hills + trees. What I did was tape a small pencel flash light to the barrel of my gun. If you notice, in the center of the beam of light if you aim it at a wall or celling you will see a black or darck spot in the center of the circle of light about 3 to 6 inches across. When taped to a gun barrel, the bullet will strike exactly in the center of the black dot in the light. All I had to do was spray them as if it was a water hose; there was no need to use the gun sights."
Alfred Hitchcock Presents titled “Museum Piece” originally broadcast on April 4, 1961.
In that episode, some of the narration is as follows:
“He’d invented a fool proof gadget for night shooting. A spotlight mounted on his 22 in such a way that his shot would strike the exact center of light.”
The narration also includes this line,
“I remember the excitement of the manhunt. The most dangerous game.”
Ross had an interesting connection to the show "Alfred Hitchcock Presents."
When Ross was in high school, his close friend was producer Allan Silliphant. Allan Silliphant had an older half brother, TV writer Stirling Silliphant.
Stirling Silliphant wrote many episodes of Alfred Hitchcock Presents between 1956 and 1959.

-The Stirling Silliphant episodes aired when Ross and Allen were in high school.
-Jon Sullivan is reported to have lived with Stirling Silliphant around this time as well.
-Stirling Silliphant also wrote the 3rd Dirty Hary film “The Enforcer.” The first Dirty Harry film was loosely based on Zodiac.
It would be even better if you could find any mention in the Californian newspapers of the movie "Charlie Chan at Treasure Island" airing on TV from July of 1969 until 4th of August (the Zodiac debut letter).
