Washington
(ANI):
Hollywood
actor
Heath
Ledger's
death
investigation
has
been
closed
after
prosecutors
decided
not
to
pursue
a
criminal
case.
Ledger,
who
was
found
dead
at
his
Soho
apartment
on
January
22
accidentally,
died
of
drug
overdose.
The
decision
comes
after
actress
Mary-Kate
Olsen
was
demanding
immunity
before
answering
questions
about
the
death
of
her
close
friend
and
his
drug
use,
reports
People
magazine.
Reports
claim
she
was
the
first
person
called
by
a
masseuse
who
found
the
28-year-old
Dark
Knight
actor
dead
in
his
Manhattan
apartment.
Since
Ledger
died
of
a
cocktail
of
Oxycotin
and
Vicodin
two
powerful
painkillers,
officials
wanted
to
find
out
the
sources
of
the
substances.
