I received this information from another member (gatorojo) of the recent death of Thomas Regan, known on another site as Tripwire, and GreenBeret1631 on this Site.
Here is a eulogy posted on another site :
It is with great sadness I bring news of the passing of Thomas Regan aka Tripwire(GreenBeret1631). I don't know the details of his passing but he will be missed by many. Thomas was in his late 80's and did more than most will do in 3 lifetimes.
He was a true Soldier, with duty in Korea and Japan, as a Ranger and as a SF Engineer, a Patrol Officer and a SWAT Leader, diver, and Admin officer in the Seattle Area.
Rest easy Warrior, you've earned it along with the respect of many. You will be missed by all who had the privilege of interacting with you even at the slightest level.
You have earned your spot at the Big Table.
