FIGHTING CRIME: How Guns Can Be Linked To A Crime Scene & How Finger Printing Guns Is Done

Published

on

President Yoweri Museveni during his address on the state of security in the country yesterday at parliament laid down 10 measures  goverment is going to undertake to fight insecurity in the country.

The first measure was to finger-print all legally held guns. The president said, “All legally held guns will be finger-printed. When this happens, once a cartridge is fired, we shall be able to tell which gun discharged the bullet. If any legally-held gun is used in crime, we shall trace it, this includes guns in private hands but licensed by the police.” Below are some of the ways guns can be linked to a crime scene and what the president meant by finger printing guns:

Guns and bullets are used in the most serious crimes, and they also happen to leave the most damning evidence.

While it’s often obvious when initially walking into a crime scene whether a gun was used – even if the victim survived and is being treated by paramedics – a full examination of the scene is always required to look at all factors that impacted the event. When a gun is involved, however, crime scene investigators will look for specific clues such as bullet casings, bullet holes, spatter patterns, and perhaps even a dropped weapon – either at the scene or nearby, such as in a body of water or a dumpster.

After the scene is photographed, diagrammed and all evidence referenced, the shell casings, bullet fragments, weapons and other evidence can be gathered, preserved and catalogued for further study back at the lab. Bullets suspected to be drilled into soft plaster or furniture will not be pried out. The area around and containing the bullet will be cut out so that the bullet can be removed carefully at the lab, and thereby preserve the channel that the bullet made.

1. Striations on a fired bullet

Once a bullet is recovered, either from an impact point in a soft wall or pulled out of flesh by a medical examiner or a physician, that bullet will become a primary piece of evidence. Every gun barrel is rifled during manufacture, or finished inside the barrel with rotating grooves to impart spin to a bullet in order to improve accuracy during flight. The resulting spiralling grooves and lands (the flat parts between the grooves) leave mirrored markings on the bullet itself.

If you are able to fire another bullet from the same gun, an investigator can match the grooves under a special microscope which displays both bullets side by side, comparing the strata. Since there are several processes involved in rifling a barrel, each barrel is unique. Just like fingerprints, a bullet can be paired to a weapon with nearly perfect accuracy.

Further, even without a weapon, the striations can identify a type and model of firearm, so detectives will know what to look for.

2. Gunpowder residue leaves expected patterns

When a gun is fired, the bullet is not the only thing that comes out of the barrel. Burning powder particles also expectorate and will create a pattern on the object closest to the barrel. This pattern varies by how far the weapon is from the target. By knowing the patterns of a particular firearm, a consensus can be reached about how close or how far away the gun was. If there are no powder marks on the hand holding the gun or the forehead around the bullet hole, it is unlikely that the victim shot himself, so suicide can be ruled out no matter how convincing the pose looks to the untrained eye.

3. Trajectory, ricochet and bullet holes

Sticks carefully inserted in bullet holes can indicate direction of the bullet, and, if many holes are found in a scene, these sticks can help triangulate: where the shooter was standing; how tall he (or she) might have been; and many more details. Bullets that ricochet will collect trace evidence from where they bounce, and add further detail for the investigator.

4. Hidden fingerprints

A gunman will finger bullets as he loads them into a cylinder or magazine, and leave tiny quantities of salty sweat with each touch. When a bullet is fired away from its casing, tremendous heat is instantly transferred to that metal, vaporising the moisture and setting the salts from those prints. The salts become molten and a chemical reaction with the metal etches the fingerprints permanently into the casing.

5. Firing pin impressions

Firing pins leave individual marks on the primer (the explosive cap that ignites the gunpowder when struck by the pin on the tip of the hammer) at the very bottom of each bullet. The alignment, size of impression, and age of the firearm also contribute to individualised marks as the hard metal (the pin) make impressions on the soft metal (the primer).

6. Bullet damage to tissue

Wounds can provide an incredible amount of information about sequence of hits, distance, velocity, bullet type, caliber, and more – whether a bullet fragment is recovered or not. Bevelling around an entrance wound holds clues, fracture lines in dense bone such as skulls can identify distance, velocity and direction of fire. Grazing bullets leave skin tags – little flags of ragged skin that are pulled up and torn as a projectile passes by at high speed. All of these indications help validate the opinions of a medical examiner.

How My Private Parts Were Electrocuted, Tied And Pulled On Kayihura’s Orders – Tortured Kaweesi Suspect Speaks Out, Asks Kaka To Chop Off Kale’s Balls

Published

on

A few days after former police spokesperson Andrew Felix Kaweesi was assassinated, a number of suspects were arrested to help police with the investigations.

Among those arrested included Ahmed Ssenfuka a local farmer in Kayunga Mukono district. While narrating his ordeal, Senfuka told our reporter that he was arrested by operatives from the police flying squad Unit which was commanded by Herbert Muhangi.

Upon his arrest, he was moved to Nalufenya  detention centre which used to handle high profile criminals and suspects in high profile cases during Kayihura’s tenure as police chief. Ssenfuka says that while in Nalufenya, he met Kayihura on two occasions, during one of the meetings, he met Kayihura at 1:00am, he asked him to accept that he was in the plot to kill Kaweesi.

He adds that Kayihura promised him heaven on earth if he accepted that he killed or knows who killed Kaweesi. However, when he was taken back to the cells to think about the general’s proposal, he confided to one of his friends he trusted most about his meeting with Kale and what he was offered. His friend advised him not to risk since his yes would mean life imprisonment. He adds that in the next meeting, he refused the offer and when Kayihura left, he started experiencing the Nalufenya hell.

“It’s true Kayihura met me and promised me cars and houses to accept that I killed Kaweesi but I refused. I thought he was doing his investigations and would do nothing to me but when I refused his offer, his men began brutalizing me,” Ssenfuka narrates. He says that his private parts were electrocuted, tied with wires and pulled. He adds that his eyes were also sprayed with pepper and he was caned daily. Other torture acts were done on him daily.

He adds that he was saved by human rights organisations who intervened in the matter and he was moved from Nalufenya to Luzira. Ssenfuka states that a few hours before they were moved to Luzira, one of the flying squad operatives made a call to Kampala and within a few minutes, a van carrying other Kaweesi suspects entered Nalufenya.

He says, “we were six people who were arrested over Kaweesi assassination but on the day, we were moved to Luzira, we were joined by some other people we did not know who travelled with us. One of them told us that he had married a sister to Henry Tumukunde’s wife. Surprisingly, when we reached Luzira, these guys were known and this is when we learnt that the guys we moved with from Nalufenya to Luzira were spying on us and had a mission to end my life in case I raised my tongue and said what Kayihura had asked me to do.”

He adds that later, one of them confided to them that they were sent to spy on them.

ASKS KAKA CHOP KALE’S BALLS OFF

Senfuka says that he still receives nightmares of what he went through in Nalufenya. He adds that he pins the former police boss for is current predicament and even if they detain him for years in Makindye, it won’t wipe away his tears and the pain he is going through after the Nalufenya incident.

Ssenfuka says his dream right now is to be allowed to pay a visit to the man (Kale) who ordered his torture well knowing he was innocent. Ssenfuka also asked ISO boss to chop off Kayihura’s balls if possible or hand him over to relatives and friends of the Muslims his regime tortured innocently. Kaweesi was killed on 17th March 2017 together with his body guard and driver a few meters from his home in Kulambiro a Kampala suburb.

Nelor diaspora initiative CEO Ssesanga Barte giving Ssenfuka some cash

SENFUKA GIVEN HELP

While meeting Nelor diaspora initiative CEO Ssesanga Barte who had taken some help from the diaspora to Senfuka, since he can no longer work for his Family due to the injuries he sustained while in the detention, Ssenfuka said that the inhuman acts of torture done on him killed his manhood.

“Ssenfuka now can’t work both in bed and for a living. Ugandans working in diaspora led by Aisha Bahati raised a sum of one million five hundred thousand shillings and a motorcycle to see that Senfuka gets a better life,” Ssesanga said while handing over a package to Ssenfuka.

KAYIHURA RELATIVES TURN TO GOD

Meanwhile the family of booted and former police boss Kale Kayihura launched prayers day for the general at Mulago church saying they have realised it’s only God to save the General.

Security sources have told the Grapevine that the new police investigation team on Kaweesi murder led by Grace Akullo the CIID boss have handed in their report to the president. Kayihura is currently detained at Makindye military barracks with no charges against him yet.
