Mary
Kate
Olsen
has
refused
to
answer
questions
from
Drug
Enforcement
Agency
-
the
agency
which
is
probing
Heath
ledger's
death.
The
actress,
being
the
first
to
hear
about
the
actors
death
from
his
masseuse,
is
the
immediate
focus
of
the
investigation.
But
she
refuses
to
let
the
cat
out
of
the
bag
without
immunity
from
the
prosecution.
Her
lawyer
Michael
C
Miller
claims
that
she
has
nothing
to
with
the
drugs
that
the
actor
dies
under
the
influence
of.
Olsen's
party
has
furnished
all
the
information
required
by
the
investigating
authorities
that
was
required
of
them
and
has
categorically
stated
that
the
Olsen
twin
has
no
knowledge
of
any
drug
related
activity
that
could
have
spurned
the
actors
sudden
death.
