. Nazi spy because DR.. Ignatz I
Griebl put the finger" on him TO
me.
Griebl first told me Voss' nam
and that he was an important Naz
aviation spy. I wanted to max
sure. I asked Griebl to put Vos
''on the spot" for us, so that w
\ could trail him and check up be
fore we closed in.
Griebl agreed readily. He callet
Voss in for physical examination
and two F. B. I. agents were sitting
in the waiting room of Griebl's Of
alce when Griebl came out, greeted
him by name, then left him waiting
a few minutes so the F. B. I. mer
could get good look.
For solid week we were able Il
trail him night and day and CHECK
on his bank accounts and connec.
tions, without rousing his suspi.
- cions, thanks to DR.. Griebl. W.
found that though Voss earned only
an average of $45 week he hac
between $1,000 and $4,000 in the
bank.
sWhere did the money come from?
s,He was working in the expert
mental section of the Seversky air
craft plant at Farmingdale, Long Is
land. Seversky was building fast
pursuit planes for the United States
Army.
W Voss Called Into Office.
sOn March we closed in on him
Fl B. I. Agents w. Callahan and ]. T
Mclaughlin, who worked day and
night with me on the case and did
Immensely valuable work, went with
u1e out to the Seversky plant. We
got the general manager to call
Voss into his Office.
Voss paled when I told him who
We were, but showed no other sign
Of emotion.
t"Yes, sir" he said. His voice was
thlckly accented. What do YOU
wish Of me? If it is about airplanes
must have the permission of the
general manager before 1 can help
you"
This was a shrewd remark, but
the manager merely said: Go with
the Government men, Voss, and tell
them anything they want to know"
Voss nodded and said no more
until we were in the car and on our
Way.
Where are you taking me?" he
asked.
ITO F. B. I. headquarters in New
York." told him.
But why?"
Because, Voss," I shot at him,
you are Nazi spy!'
His keen blue eyes behind the
silver-rimmed spectacles, widened
under the shock, then narrowed.
He shook his head.
THAT is not true" he muttered,
1T Is a mistake"
I'VE will soon see,' said.
Then he said:
Il would like to stop at my house
I want to tell my wife"
Guess at Motive.
We knew, from our surveillance.
that his wife was not at home. What,
then, was his motive? 1 decided
there were probably papers he
wanted to destroy, and hoped we
would let him go into the house
alone. I decided to appear to play
his game and let him lead us to
those papers. We drove to his home.
That turned out right. He hesi-
tated when he saw we were deter
mined to enter the house with him
But said: while we are here we
would like to see if you have anv
confidential airplane blueprints hid
den in your house."
He couldn't very well refuse.
realizing we could quickly get
search warrant, and that his refusal
would look suspicious. Besides. he
knew he had no blueprints in the
house. So he gave his permission.
/ He was a very methodical man.
This Voss. In his desk we found
every letter, every bill he had re-
celved in the last 10 years. neatly
nled. We also found a diary-and
that is what finally broke him. We
took that along with us.
At F. B, I. headquarters he stolidlv
maintained his innocence under
more than 10 hours of questioning,
1t began to look bad for our case
against him, since we had only DR.,
'Griebl's statement so far that Voss
was Nazi spy.
Note for S185 Found.
So turned the questioning over
to another agent, and retired to a
quiet spot with the diary. And one
OF the first things I found, folded
between two pages, was a note for
$l85, dated three years previous.
The signature was that of William
Lonkowski, that spy, who had played
so great a role in setting up the Nazi
spy ring in this country.
Flipping through the pages of the
diary, I saw names which intrigued
my curiosity as an investigators:
Then ran into another name. I
read that entry carefully, then
closed the diary and walked into
the room where Voss was. For that
name was "Dr. Ignatz T. Griebl."
