Vladislav Roslyakov

His clothing resembled that of Eric Harris, one of the perpetrators of the 1999 Columbine High School massacre, leading to speculation that the massacre was a copycat crime.

According to some Russian tabloids, he had been a member of various Eric Harris and Dylan Klebold fanclubs on social networks, and had informed friends of his belief that "it would be good to have a massacre", specifically referencing Columbine High School massacre as an example.

Furthermore, he had mentioned his belief in the two perpetrators being "awesome".

Like perpetrator Eric Harris, Roslyakov committed suicide in the library of the college, by shooting himself with his shotgun,

The attack was perpetrated by a fourth-year student of the college, Vladislav Igorevich Roslyakov (Владисла́в И́горевич Росляко́в, 2 May 2000 - 17 October 2018).

He was 18 years old at the time of the massacre.

When Roslyakov was around ten years old, his parents broke up when his father sustained a severe head injury, after which he became disabled, started drinking alcohol, and abused Roslyakov, his mother and other relatives.

Roslyakov studied at a local school with no interest and poor grades.

He had few friends and his hobbies included weapons and video games.

It was the deadliest school shooting in the former Soviet Union since the 2004 Beslan school siege.

In 2015 he joined the college to study to become an electrician.

In college he developed an interest in explosives and weapons and started to take a knife bayonet to class.

One day he discharged pepper spray in a class and failed to explain his actions.

His mother, a Jehovah's Witness, limited his social activity, searched his pockets and refused to allow him to go to the cinema or use a computer, only allowing the latter when he turned 16.

In the days immediately before the attack, Roslyakov stated that he did not believe in the afterlife.

On the eve of the attack, according to neighbours, Roslyakov burned a Bible in which he had highlighted verses, along with his mobile phone, and other books.

A friend has claimed that Roslyakov "hated the polytechnic very much" and had vowed revenge on his teachers.

There were also reports that he may have been bullied.

In the days before the attack he discussed ignorance by others, the lack of purpose in his life, mass shootings and suicide on social media.

Roslyakov was in a number of online communities dedicated to serial killers.

Surveillance footage of the incident shows Roslyakov wearing black trousers and a white T-shirt emblazoned with the Russian word "НЕНАВИСТЬ" ("HATRED") as he carries an eight-shot 12 gauge Hatsan Escort Aimguard pump-action shotgun with a pistol grip.

The Kerch Polytechnic College massacre was a school shooting and bomb attack that occurred in Kerch, Crimea, on 17 October 2018, when 18-year-old student Vladislav Roslyakov killed 20 people and wounded 70 others before committing suicide.

Vladislav Roslyakov purchased a shotgun on 8September 2018 and bought 150rounds legally at a gun shop on 13October 2018.

He entered the grounds of Kerch Polytechnic College on 17October 2018 at about 10:02 a.m. A survivor of the incident said that the shooting lasted for more than 15minutes.

Multiple witnesses recounted an individual gunman strolling through the corridors of Kerch Polytechnic College, discharging shots indiscriminately at classmates and teachers.

He also fired at computer monitors, locked doors, and fire extinguishers.

A large nail-bomb was detonated during the attack, and local police said that they deactivated more explosives on the campus.

However, there was initially variation in survivors' accounts of the incident, with some claiming that a large bomb exploded and others describing only gunfire and the use of grenades.

The town website claimed that the explosion occurred on the first floor although the shooting occurred on the second.

CNN reported that state television channel Russia-24 said that 200military personnel had been sent to the location.

Eyewitness accounts differ about the time it took for law enforcement to respond, as times differ between 10 and 15minutes even though a police station is across the street, within 300 m of the college.

The massacre ended when the gunman committed suicide in the college's library.Graphic video footage of the attack was captured by school surveillance cameras and later posted on both the news programme Vesti.Krym's YouTube channel and on its website.

This footage was removed from both sites shortly afterwards.

Russia's National Anti-Terrorism Committee said that most of the victims were teenagers.

Fifteen students and five teachers died.

The Kerch Deputy Mayor, Dilyaver Melgaziyev, initially clarified rumors on 18 October that six of the deceased were under the age of 18.

This figure was later revised to eleven.

Crimean authorities have published a list of the initial 20 victims who were killed.

The Russian Health Minister Veronika Skvortsova told reporters that a total of 70 people were wounded, 10 of whom were described as being in a "critical" condition, including five in comas.

Crimean State Council speaker Vladimir Konstantinov announced that the victims' families would receive financial compensation, with preliminary discussions suggesting that the payments would be 1 million rubles (USD ) from the Russian federal budget and 1 million rubles from the local budget.
