ELEMENTS of Homicide:
1. That a person was killed;
2. That the accused killed him without any justifying circumstances;
3. That the accused had the intention to kill, which is presumed; and
4. That the killing was not attended by any of the qualifying circumstances of murder, or by that of parricide or infanticide.

Intent to kill is conclusively presumed when death resulted. Hence, evidence of intent to kill is required only in attempted or frustrated homicide.

There is no crime of frustrated homicide through negligence/imprudence.

Physical injuries are one of the essential elements of frustrated homicide.

Use of unlicensed firearm is an aggravating circumstance in homicide.

In accidental homicide wherein death of a person is brought about by a lawful act performed with proper care and skill and without homicidal intent, there is no liability.

When the wounds that caused death were inflicted by 2 different persons, even if they were not in conspiracy, each one of them is guilty of homicide.

In all crimes against persons in which the death of the victim is an element, there must be satisfactory evidence of
(1) the fact of death and
(2) the identity of the victim.

Penalty shall be one degree higher than that imposed by law when the victim is under 12 years of age

When several assailants not acting in conspiracy inflicted wounds on a victim but it cannot be determined who inflicted which would which caused the death of the victim, all are liable for the victim’s death.

In attempted or frustrated homicide, there is intent to kill. In physical injuries, there is none. However, if as a result of the physical injuries inflicted, the victim died, the crime will be homicide because the law punishes the result, and not the intent of the act.

Corpus delicti – actual commission of crime charged

PEOPLE vs. DELA CRUZ, G.R. No. 152176, 10/1/03
 The qualifying circumstance of treachery was not sufficiently established by the prosecution. The prosecution witness did not see the actual stabbing of the victim. Therefore, there is no way of determining on how the attack was initiated. In the same way that no testimony would prove that the appellant contemplated upon the mode to insure the killing. The crime committed by appellant is homicide.

GOROSPE vs. PEOPLE, G.R. No. 147974. 1/29/04
No error was committed by the trial court in characterizing the felonious assault as frustrated homicide and convicting appellant therefor. The appellant acted with intent to kill in firing the gun at
Miguel. Usually, the intent to kill is shown by the kind of weapon used by the offender and the parts of the victim’s body at which the weapon was aimed, as shown by the wounds inflicted.

ARADILLOS vs. COURT OF APPEALS G.R. No. 135619, 1/15/04
An accused may be convicted of slight, less serious or serious physical injuries in a prosecution for homicide or murder, inasmuch as the infliction of physical injuries could lead to any of the latter
offenses when carried to its utmost degree despite the fact that an essential requisite of the crime of homicide or murder - intent to kill - is not required in a prosecution for physical injuries.

People v. Castillo
There is no offense of frustrated homicide through imprudence. Accused pharmacist prepared the medicine on prescription but erroneously used a highly poisonous substance. When taken by the patient,  the latter nearly died. Accused is guilty only of physical injuries through reckless imprudence. The element of intent to kill in frustrated homicide is incompatible with negligence or imprudence.
