CHICAGO. March 23.-Chicago gang
sters are employing a cartridge with q
steel Slug Ct such hardness that it may
oalk efforts to trace the gun from which
1t was fred through use of the new
science of ballistics.
This was disclosed yesterday at ar
inquest over the body of Johnny Gena-
70, Capone henchman, slain Saturday
night.
In Genaro's head, DR.. l. M. Feinberg
coroner's physician, found a half-inch
ball bearing. which apparently had been
fired from a large revolver or an auto
matte pistol. On the floor of the auto
mobile in which the gangster was riding
when enemies dispatched him were
others of these tough steel globules.
Through ballistics, police have been
able to trace common lead and alloy
slugs, because they bear marks of the
weapon barrel The ri1ing markings OF
no two barrels are exactly alike, and as
a result the markings help complete the
trail of cluss to gangland aSsassins.
But the bearings apparently bore no
marks, Feinberg said. and he believed
them to be of specially treated steel,
tougher than the ordinary.
Used First Time.
At have never heard Of their use be-
fore" he said THEY must be some
new subterfuse adopted by desperate
gangsters TO cover a clue which bal
listics disclosed"
BY the strangest of condolences, the
Staying Of Genaro harked back to the
first major cases in which the science
OF balliStics was used to trace the killers.
When the desperate, Fred Burke, who
still is at large with a price on his
head, killed policeman and fed from
his hideouC at st. Joseph, Mich, police
found two machine guns in his home.
Mai Calvin Goddard, balliSticS eX-
pert. established that one of these gins
had been used in the Staying of frankie
Uale, Brooklyn gang leader. And Ge-
marc, an associate of Burke, was once
held as suspect in the Uale killing.
Eight Men Quizzed.
These same ballistics tests enabled a
coroner's Jury in Chicago to name Burke
as one of the men who executed seven
members OF the Bugs Moran gang in
a North Clark street garage-the st.
Valentines DAY massacre. Genaro was
also suspected Of participation in the
killings.
Coroner Herman Bundesen, who has
been fostering the science Of ballistics,
took possession of the bearings. He
planned to turn them over to Col.
Goddard, head of the Northwestern
University Crime-Detection Laboratory
and chief student. of the science.
Eight men were rounded up last night
for questioning about the Staying OF
Genaro, but police thought it likely the
case would have to go down in the
books as unsolved.
They viewed Genaro's death as the
climax of q feud between two rival
South Side gang can1ps-one headed by
"Pepe" Genaro, brother Of the slain
man and No. 26 on the list of public
enemaies; the other captained by Jimmy
Belcastro, public enemy No. S, and
Rocco Fanelli, No. 7.
It was recalled that Genaro was am
pushed last year, and in the belief death
was near, he told detectives. Belcastro
hirelings had fired on him. He re-
covered, only to die last night at the
wheel Of his automobile as he drove
home.
