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.

Kirumira Murder Investigation:  Until His Death, Museveni Wasn’t Aware That Slain Cop Was Detained At Nalufenya During Kayihura Tenure

Published

on

President Museveni has said that he was not aware of the detention of slain Buyende District Police Commander (DPC) Muhammad Kirumira at Nalufenya.

In a meeting with president Museveni at Nakasero state lodge, the executive members of late Muhammad Kirumira‘s Nalufenya torture victims group were shocked after the president revealed that he never knew that Kirumira was at one time arrested  and detained at Nalufenya during general Kale Kayihura’s tenure as Inspector General of Police (IGP).

Led by Rt. Maj Godfrey Galabuzi  Musisi,  the group had met the president to hand in another report  on why the slain cop was at war with his superiors in the police force and why he might have been killed.

According to a source who also attended the meeting, Museveni said that until this meeting, he has not been aware that Kayihura sent Kirumira to Nalufenya police detention centre which is now Nalufenya police station.

“On receiving the report with the signature of the late Kirumira as the chairman, M7 asked Maj Galabuzi if indeed Kayihura had taken Kirumira to Nalufenya.

He even called Maj Gen. Proscovia Nalweyiso to cross check and Nalweyiso answered in the affirmative,” a source said.

The group that met the president in late hours also included BK Bukenya who was arrested by police and displayed by the then IGP Gen Kale Kayihura  as the man who was behind the rampant panga attacks and killings also known as ‘Bijambiya’ before he was later cleared by ISO and other security groups for being arrested in error.

During this meeting, it’s said the Commander in Chief also promised security to the Nalufenya team who felt that their lives were in danger.

We were also told that the president cleared those with military background to get armed if they so wished to boost their security.

Just like former police spokesperson Andrew Felix Kaweesi, Kirumira was also assassinated a few meters from his home.

Family Of Kirumira’s Alleged Killer Who Was Shot Dead By CMI Drags Gen. Muhoozi , Minister Jeje Odong, Gov’t To Court

Published

The family of Abdulraham Kateregga who was killed by Uganda People’s Defense Force (UPDF) Operatives for masterminding the killing of Muhammad Kirumira the former Police Commander Buyende District has dragged General David Muhoozi the commander of UPDF, General Jeje Odongo the Internal Affairs Minister and the Attorney General to court.

Farouq Kaweesa, a brother to the late Kateregga through his lawyer Ladislaus Rwakafuzi stated that Kateregga was assassinated in cold blood by members of UPDF who were in uniform. In his affidavit, Kaweesi stated that on 5th October 2018, UPDF operatives found Kateregga at his home in Luyinja Namungoona Rubaga Division and shot him without a warning. He further stated that it was UPDF which Muhoozi commands that intentionally caused the death of Kateregga who was not on death sentence pronounced by a competent court.

He noted that the killing was violent and unnatural and therefore, is a subject of an inquest under the inquest Act. Kaweesa wants court to instruct the internal Affairs minister Jeje Odongo to appoint a coroner to inquire into the lawfulness of the death of his brother.  He also wants court to issue a Habeas corpus against General Muhoozi to produce a One Mariam Kateregga.

He stated that on the day UPDF killed his brother, the same killers who were putting on UPDF uniforms also kidnapped Mariam Kateregga a wife to Kateregga. He said that Mariam was found at his home in Luyinja Namungoona Rubaga Division where they killed her husband from. He said that from that day up to now the family of Mariam has never seen or heard of her whereabouts which violates her human rights.

He stated that he was informed by his lawyer Rwakafuzi that it’s illegal and unconstitutional for any person to be detain the other in un gazette custody and asked court to order Muhoozi to produce Mariam before a competent court because she has never appeared before any judge or magistrate as stated in the constitution.

He said that Mariam left 15 children, 13 of them are her biological children and 2 are for her co-wife. He added that the children are still too young because the oldest is 17 years while the youngest is 2 years and they don’t have anybody to take care after them.  Court has not yet set a date to hear the application. Kateregga was killed by CMI operatives as he allegedly tried to run away from being arrested. President Museveni later congratulated Katerega’s killers and revealed that he masterminded the brutal murder of former Buyende district Police Commander (DPC) Afande Muhammad Kirumira and a lady friend in Bulenga Wakiso district last month.
