glass, there is a tendency to “punch”
out a section of glass its own size, but
the pressure being exerted in all direc-
tions equally, the result is that the
pane will “flake” on the side remote
from the point of entry, and there will

be a clear indication of direction.
Similarly an angle shot will leave an
oval area at the point of exit.

Some time ago there were a number
of thefts at a summer resort in which
windows of summer cottages were
broken, the sash raised, thus affording
easy entry for the housebreaker.
There had been a series of these
housebreakings, and the investigating
officers were of the opinion that they
were being perpetrated by a member
of the little community. Another
similar housebreaking occured and
the investigating officers carefully ex-
amined the broken window. While
the pieces of glass were found inside
the house, which would normally in-
dicate that the window had_ been
broken from the outside, they found
by careful examination of the frag-
ments, that the glass had actually been
smashed by a blow from inside the
house. Further investigation was
made, when the householder admitted
that he had been responsible for all
the thefts, and that to divert atten-
tion from himself, he had staged a
“housebreaking” in his own cottage.
Apparently he had carefully opened
the window which swung inwards, and
struck it a blow which caused the
glass to fall inside the house. How-
ever he had not reckoned with the
evidence which the glass itself would
give.

It has been noted that glass breaks
in radial and concentric fractures. In

tures may be totally absent. However
the radial fractures furn’sh sufficient
information. If the reader will ex-
amine a piece of broken glass, he will
note that the edge bears a peculiar
design, “scallop” effect. The size and
frequency of the “scallops” vary with
the quality, thickness, and possibly
with the age of the glass, but all glass
appears to have this point in common.
The “scallops” are something like an
“L”, one leg paralleling one surface
of the glass, then curving, and the
other leg ending at right angles to
the other surface of the glass.

These “scallops” tell quite a story.
Recalling that the glass starts to break
at the side remote from that on which
the force was originally applied, it
will be noted that the vertical part of
the scallop will always appear on the
side remote from the source of the
force. The parallel leg of the “scal-
lop” will always indicate the side from
which the force was applied. But this
is not all, the direction in which the
SeoumiSm Dent will also indicate the
point at which the force was applied.
The best way in which the reader
can familiarize himself with this
phenomenon is to break a piece of
elass and examine the edges. To test
himself, it is suggested that a red and
blue grease pencil be used, one side
of the glass scribbled in red and the
other scribbled in blue.

In determining how a piece of glass
was broken from a window, it is
necessary to ascertain which side of
the glass faced out, and which side
faced inwards. This is usually easy, as
the outside will often have particles
of dust, leaf mold, insects and so on,
while the inside may have a smoke
film or grease, depending upon the
tidiness of the housekeeper.

It will be noted from the above that
much information can be secured
from a few pieces of glass. While this
is only an outline, it must be appre-
ciated that space will not permit of

greater detail. * *
