Organic —


Inorganic

Size comparison of Entry vs. Exit wounds

Entry — smaller


Exit — bigger

This is always present in Entrance Wound

Abrasion ring or Contusion collar

Description of tissue in entry vs. exit wounds

Entry — inverted margins


Exit — everted margins

Antemortem phenomenon that indicates that the individual was alive at the time when shot — reddish-brown to orange-red coloration

Powder Tattooing

It has a moist gray or yellow appearance.

Post-mortem tattooing

Tattooing is found in what type of range in GSW?

Intermediate Range GSW

Contusion collar is formed when the bullet hits the skin and there is _______

Scraping. (Friction is the result)

If the contusion collar is wider in superior, then then the trajectory is

Downward

It can tell the trajectory and the position of the victim

Contusion collar

This looks like just a stab wound because of irregularities

Exit wound

Through and through

Perforating GSW

The presumption if the number of gunshot wounds of entrance and exit is even

No bullet is lodged in the body

The presumption if the number of entrance and exit is odd

One or more bullets might have been lodged in the body

Indication of exit wound in skull:

Bevelling or “punched out”

It’s shallow and no perforation.

Grazed GSW

It’s shallow and no perforation

Grazed GSW

Extends down through the subcutaneous tissue; skin is lacerated by the bullet.

Tangential GSW

Shallow through and through; the entry and exit are close to each other.

Superficial perforating GSW

Bullet has passed one part of the body and then re-entered another part

Re-entry wounds

When a bullet enters and does not exit

Penetrating GSW

It’s a tangential source wherein one end of the perforation will resemble a typical entrance defect, while the other end will show external beveling consistent with exit holes.

Keyhole wound

Muzzle of firearm is pressed hard against the skin — that it enveloped the muzzle. Edges of the entrance are seared by hot gases of combustion and blackened soot. Not easily wiped away.

Hard-contact GSW

Grey-black discoloration, soot is deposited in a zone around the entrance. Muzzle is held lightly.

Loose-contact GSW

Type of contact gunshot wound when gases are released by the fired round that went into the subcutaneous tissue.

Stellate-shaped contact GSW entrance wound

If there’s black soot

Close range GSW: Smudging

Yep

True or false. You can determine the caliber of a bullet based on gunshot wound.

False.

Because the skin is elastic so it’s unpredictable. But when it comes to bone, can full metal jacketed bullets produce entrance wounds in the bone the same diameter as the bullet?

Yes

The most useful aspect to be determine from the PM Examination

Range of Fire — it can tell us the manner of death whether it’s suicide (contact-immediate), homicide, or accident.

True or false. A victim may test fire the weapon before inflicting suicide.

True

Muzzle imprint or star-shaped laceration due to the gases released by the fired round which went into the subcutaneous tissue. Hard or loose and its residue is within the wound track.

Contact GSW

There’s scorching from the muzzle flame. 1-3 inches. It’s the gray zone between contact and intermediate range.

Near contact GSW

Presence of soot, smudging or smoke. 3-6 inches.

Close range GSW

2-3 feet

Intermediate range

Absence of gunshot residue. More than 3 feet.

Distant Range GSW

True or false. Clothing will filter gunshot residue.

True

The absence of evidence is not evidence of absence.

True

It’s a tangential source wherein one end of the perforation will resemble a typical entrance defect, while the other end will show external beveling consistent with exit holes.
