TRAJECTORY ANALYSIS

 Reconstruct bullet path using laser, inclinometer, trajectory rods, string. 

GUNSHOT SEQUENCE

Gunshot sequence can be determined by the perforation characteristics, angle of incidence, location of shooter, reaction time, and movement of the object being targeted.

CARTRIDGE CASE COMPARISON

 Identification/Elimination or Inconclusive to a specific firearm. 

BULLET COMPARISON

Identification - Elimination - Inconclusive to a specific firearm.

Identification/Elimination or Inconclusive to a specific firearm.

DISTANCE DETERMINATION

Distance determination by replicating the pattern of stippling, soot,  GSR, or thermal damage.

Distance determination by replicating the pattern of stippling, soot,  GSR, or thermal damage.

AMMUNITION ANALYSIS

 Examination of the various components of ammunition. 

SHOTGUN

 Shotgun discharge with flame, heat, soot, wadding with pellets and sometimes polystyrene filler. 

FIREARMS & SILENCER EXAMINATIONS

 Function testing, mechanical safeties, test specimens,  decibel levels,  altered and full auto. 

CRIME SCENE REVIEWS

Interpretation of evidence present at the scene and determining evidence which should be present but is missing.

CATASTROPHIC FAILURES

Spontaneous disassembly often results from either incorrect ammo, excessive pressure, plugged barrel, squib load, defective design, metal fatigue.

FIREARMS & HUNTING SAFETY

 Best practices and  methods when hunting and engaged in shooting events. 

GUNSHOT WOUNDS

Characteristics of a gunshot wound 

HOLSTER RETENTION LEVELS

The number of active and passive retention devices determines the rating level of the holster.

REACTION TIME

The number of gunshots fired within an elapsed timeframe can be estimated depending on the shooter's skill as published in peer reviewed treatises & testing.

FIREARM DISCHARGE DURING A STRUGGLE

Studies show that a struggle over a firearm can result in an involuntary discharge.

INADVERTENT OR INVOLUNTARY DISCHARGE

Keep figner off the trigger until the decision is made to shoot.

An involuntary or inadvertent discharge of a firearm begins with a failure to comply with safety protocols combined with one or more of the published scientific reasons for the discharge.

REVOLVERS HAVE SAFETIES

Most modern revolvers have either a hammer block safety or a transfer bar device that prevents a revolver from discharging unless the trigger is fully actuated, but some firearms do require being carried with an empty chamber.

BARREL-CYLINDER GAP GSR

Barrel-cylinder gap.

The gap between the cylinder and barrel expels significant GSR under pressure along with thermal blast that can cause serious injury.

LESS LETHAL WEAPONS

Less lethal ammunition can result in death or serious injury if not properly deployed.

CROSSFIRE

Mistakes in tactical positioning can result in injury from ricochets, fragmenting projectiles, and misdirected gunshots.

BULLETS CANNOT STOP VEHICLES

Firing at vehicles can result in death/injury to innocent occupants who do not control the vehicle.  a 180 grain bullet will not stop a 4000 lb car.

CARTRIDGE CASE PATTERN

Depending on several variables which must be considered, cartridge location may assist in providing where the shooter was located.

DEFORMED BULLETS

It is often possible to determine the basis for damage/deformation to a projectile.  Trace evidence may also be present.

TYPICAL CONTACT GUNSHOT WOUND

Contact wounds typically produce stellate tearing from gas, heavy soot, and dense stippling with evidence normally found in the wound track itself.
