The following excerpts were taken from Antonio Huneeus' article, 
"THE 'CHUPAS' -- UFO HORROR STORIES FROM BRAZIL", 
which appeared in the Summer, 1994 issue of UFO UNIVERSE:

     	(Mr. Huneeus describes the following incident that was 
investigated by APEX [Association of Extraterrestrial Investigations] 
in Sao Paulo, one of the best known UFO groups in Brazil, founded
by Dr. Max Berezowsky):
     	"...The affair began near Vitoria, the capitol of state of
Espiritu Santo north of Rio state, where there are beaches rich in
mineral contents.  It happened either in late 1979 or early 1980,
[Osni] Schwarz wasn't sure when he told the story in 1986.
	"A youngster called Aeromar sold beverages at the beach,
where one day he encountered three men dressed with suits and
tie -- highly unusual clothing for the beach, especially in Brazil --
who approached him and said they wanted to talk to him.  Aero-
mar became scared, thinking they were perhaps policemen who
wanted to implicate him in a drug case, so he avoided the beach 
for a few days.  As he returned home after dropping off his girlfriend
one night, he saw a car with the same three men inside.  He ran to
the house, but suddenly he couldn't hear well.  His mother took him
to the hospital where we was not cured, although about a month
later he suddenly could hear well again.
	"Aeromar moved to Rio, finding work at a bakery in a shift
between 4 and 11 PM.  One night, as he was crossing one of the
many tunnels that link the Rio bays, he saw two of the MIBs
walking in his direction.  The youngster ran in the opposite direction,
only to find the third MIB waiting at a bus stop.  He escaped and 
went back to the bakery, where he told his boss that the Vitoria 
police were chasing him.  The boss accompanied him to the
nearest police station to make a complaint, which he did, but he
was not believed.  The boss then convinced him that he should 
perhaps move to Sao Paulo, a bigger city where it may be easier
to go unnoticed.
	"So Aeromar moved to Sao Paulo, finding work in an
electrical company and sharing a room with another man.  he also
became friends with a vendor of beverages from Vitoria who had a
stand near a movie theater.  While hanging out there one night, a
car stopped right in front of the stand and the door opened.
	"Even through he didn't want to go, Aeromar LOST HIS
WILL and entered the car.  The door closed and he found inside --
not surprisingly -- the three same men whom he had been dodging
for months.  They drove for a while, leaving the city and entering a
wooded area.
	"The car stopped and they all walked up to a big UFO
surrounded by some sort of luminous ring and hovering above the
ground.  The men walked underneath the craft, which emitted a
ray of light and they suddenly were inside.  Still drained of any
willpower, Aeromar walked to a chair and sat down.  From the arms
of the chair appeared handles that secured his wrists.  An iron bar
then pressed his forehead backwards while another gadget fast-
ened his neck.  Up to here the men were always dressed with
suits, but at this point an incredible transformation took place: the
MIB'S HEAD RIPPED OPENED INTO A HEART SHAPE AND
THE SKIN BECAME GREEN AND SCALED LIKE A REPTILIAN.
Take into account that while the popular image of the MIB was
well known 14 years ago, the idea of reptilian abductors was then
not in vogue as nowadays.
	"Be that as it may, the UFOnauts proceeded to (vocally? -
Branton) interrogate and tell him things that were going to happen 
both to him and the earth.  To make the story even more 'Hollywood-
esque', a door in the room opened at one point and Aeromar was
able to peek at HUMAN CORPSES HANGING BY THEIR FEET
FROM HOOKS.  The man naturally became traumatized, re-
remembering only that his straps were loosened.  Everything went
blank after that...
	"Aeromar's conscious recollection places him next back
at the theater, but several hours later since there was no traffic in
the streets.  He returned to his room in panic and began to tell the
story to his roommate.  A strange force PUSHED HIS BODY, how-
ever, throwing it AGAINST THE WALL in front of him, as he
remembered the aliens had told him that he shouldn't speak about
the experience or he would suffer.  Aeromar cried for a while, not
knowing what to do.  A few days later, his friend contacted the
Globo TV network, which was working on a UFO documentary.  
Globo, in turn, passed the tip to Dr. Max Berezowsky.  Aeromar
and his roommate went to APEX on a very busy day when the office
was full of people.  They told the whole story to Dr. Berezowsky
and a few assistants, Osni Schwarz among them.
	"Berezowsky attempted to do hypnotic regression with the
witness, but there was too much interference in the office and
Aeromar was in total panic.  He was saying that 'they' were going
to take him on the next Thursday and that a UFO was going to land
in a Sao Paulo neighborhood on Tuesday night.  A crowd of people,
in fact, went that night to the supposed landing site but nothing
happened.  Although Dr. Berezowsky was in touch with Aeromar,
HE VANISHED A FEW DAYS LATER AND NOBODY EVER SAW
HIM AGAIN>  I wrote down at the end of my notes on this affair,
'the whole case is like a UFO horror movie.'"
