All followers of the three (3) great Abrahamic religions, Judaism,
Christianity and Islam believe in the Ten (10) Commandments. In our humble
opinion, if anyone killed another innocent human being or himself, he is neither
a Jew, nor a Christian, nor a Muslim, because he disobeyed one of the
most important Commandments of Almighty God (Allah): Thou Shall Not Kill.
……..

Given below are some of the verses from the Holy Qur’an in support
thereof, referring to the number of Surah (Chapter) first followed by
the number of Ayah (Verse), later (from an English translation of the
Holy Qur’an by Mr. Muhammad Marmaduke Pickthall).

Yet ye (Children of Israel) it is who slay each other and drive out a
party of your people from their homes, supporting one another against
them by sin and transgression, and if they came to you as captives ye
would ransom them, whereas their expulsion was itself unlawful for you.
Believe ye in part of the Scripture and disbelieve ye in part thereof?
(2:85)

Lo! those who disbelieve the revelations of Allah (God Almighty), and
slay the Prophets wrongfully, and slay those of mankind who enjoin
equity: announce them a painful doom. (3:21)

O ye who believe! eat not up your property among yourselves in
vanities: but let there be amongst you traffic and trade by mutual good-will:
nor kill (or destroy) yourselves (commit suicide): for verily Allah hath
been to you Most Merciful. (4:29)

Never should a believer kill a believer; but (if it so happens) by
mistake (compensation is due): if one (so) kills a believer, it is ordained
that he should free a believing slave and pay compensation to the
deceased’s family, unless they remit it freely. If the deceased belonged to
a people at war with you and he was a believer, the freeing of a
believing slave (is enough). If he belonged to a people with whom ye have a
treaty of mutual alliance, compensation should be paid to his family
and a believing slave be freed. For those who find this beyond their
means (is prescribed) a fast for two months running: by way of repentance
to Allah: for Allah hath all knowledge and all wisdom. (4:92)

If a man kills a believer intentionally, his recompense is Hell to
abide therein (for ever): and the wrath and the curse of Allah are upon him
and a dreadful penalty is prepared for him. (4:93)

For that cause We decreed for the Children of Israel that whosoever
killeth a human being for other than manslaughter or corruption in the
earth, it shall be as if be had
killed all mankind, and whoso saveth the life of one, it shall be as if
he had saved the life of all mankind. Our messengers came unto them of
old with clear proofs (of Allah’s sovereignty), but afterwards lo!
many of them became prodigals in the earth. (5:32)

They are losers who besottedly have slain their children without
knowledge, and have forbidden that which Allah bestowed upon them, inventing
a lie against Allah. They indeed have gone astray and are not guided.
(6:140)

Say: “Come I will rehearse what Allah hath (really) prohibited you
from”: join not anything as equal with Him; be good to your parents: kill
not your children on a plea of want; We provide sustenance for you and
for them; come not nigh to shameful deeds whether open or secret; take
not life which Allah hath made sacred except by way of justice and law:
thus doth He command you that ye may learn wisdom. (6:151)

O Prophet! when believing women come to thee to take the oath of fealty
to thee that they will not associate in worship any other thing
whatever with Allah, that they will not steal, that they will not commit
adultery (or fornication), that they will not kill their children, that
they will not utter slander intentionally forging falsehood, and that they
will not disobey thee in any just matter then do thou receive their
fealty and pray to Allah for the forgiveness (of their sins): for Allah
is Oft-Forgiving Most Merciful. (60:12)

Kill not your children for fear of want: We shall provide sustenance
for them as well as for you: verily the killing of them is a great sin.
(17:31)

And slay not the life which Allah hath forbidden save with right. Whoso
is slain wrongfully, We have given power unto his heir, but let him
not commit excess in slaying. Lo! he will be helped. (17:33)

And those who cry not unto any other god along with Allah, nor take the
life which Allah hath forbidden save in (course of) justice, nor
commit adultery and whoso doeth this shall pay the penalty; (25:68)

The people who are undecided about charging this boy for defending his mother should never be allowed to hold public office.
The Chief of Police should give the kid an award, and the City Fathers should give him the Key to the City for a day.
