Need help

Dear Sirs

I am currently writing a book about a serial killer. The murderer described his killings in missives send to local newspapers. In one of the missives, he described a seemingly prehistoric pistol- laser sight. Does anyone know whether laser sights existed in 1969? And whether this technique was common?

Here is the description:
(1969): Last Christmass In that epasode the police were wondering how I could shoot + hit my victims in the dark. They did not openly state this, but implied this by saying it was a well lit night + I could see 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 ceiling 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 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. I was not happy to see that I did not get front page coverage.”


Thanks

I started seeing the first pistol mounted lasers about the mid 70s. They were about as big around as a carton of cigarettes and about 8 inches long. I can't remember the manufacturer, but I have seen the clunky things in movies before.
