The shootings were around 1983. I can remember posting as the Yardmaster on 21 track with two armed cops and closed circuit TV's. I started posting like three days after the Amtrak Engr. was killed. In this day and age it is unbelivable that "Flash" would be back to work in three days.
The other posters were correct that the shooter was never caught and they thought it might have been a disgruntled Amtrak employee. And there were some leads that he may have gone to California. When the PD searched the old underground tunnels to the hotels and post office for him they roused a lot of homeless people and also discovered a few bodies, but they were all vagrants who had died of natural causes.
But back to "Flash" ... my best memories of him were that before I became a Yardmaster I worked as a midnight clerk up in the Movement Bureau. No sooner had we talked to a disabled or trouble train then Flash was on the air and responding. Sometimes, two, three or four times a night and all over the Island. And this is all after a FULL days work.
As a Yardmaster I can't tell you how many times he took my butt out of the bag. He'll be missed by all of us, but most of all by the LIRR.
Happy, healthy and prosperous Flash ... you deserve it !
