vladislav roslyakov :the man behind Crimea's college massacre - Fast Facts

MOSCOW - At least 18 people were killed -most of them teenagers -- and about 50 more injured following an attack in Russian-annexed Crimea, according to Russia.

An 18-year student strode into his vocational school in Crimea, a hoody covering his blond hair,then pulled out a shotgun and opened fire on Wednesday, killing 19 students and wounding more than 50 others before killing himself.

It wasn't clear what prompted Vladislav Roslyakov, described as a shy loner, to go on the rampage. A security camera image carried by Russian media showed him calmly walking down the stairs of the school in the Black Sea city of Kerch, the shotgun in his gloved hand.

"He was walking around and shooting students and teachers in cold blood," said Sergei Aksyonov, the regional leader in Crimea.

The footage, obtained by several Telegram channels, including Mash, shows a group of female students and their teacher desperately looking for a way out of the building, while all hell is breaking loose around them.

There are sounds of shots being fired in the vicinity and screams of horror as the witness begins to film. “They’re shooting from an automatic weapon,”

Then the battered camera depicted dead bodies lying in the stairs as the terrified students watched them. However, they were able to avoid confrontation with the gunman and flee to safety.

Officials said the fourth-year student killed himself in the library of the Kerch Polytechnic College after the attack. His mother, a nurse, was helping to treat victims at a local hospital after the shootings, unaware yet that her son was accused of the rampage and was already dead.

By the end of the day, the death toll stood at 19, though it was not clear if that figure included the shooter. Fifty-three people were wounded, including 12 in serious condition, Crimean authorities said.

The announcement that the shooter in Wednesday's attack was a student who acted alone came after hours of rapidly shifting explanations as to what exactly happened at the school.

Officials at first reported a gas explosion, then said an explosive device had ripped through the cafeteria during lunchtime in a suspected terrorist attack.

Witnesses, however, reported that victims were being killed by gunfire. The Investigative Committee, Russia's top crime investigation agency, eventually said all the victims died of gunshot wounds.

Reflecting the daylong confusion, Russian President Vladimir Putin said the victims were killed by an explosion just as the Investigative Committee was announcing they were fatally shot.

A somber-faced Putin deplored the attack as a "tragic event" and offered his condolences to the victims' families at a news conference in the southern city of Sochi, where he was meeting with Egyptian President Abdel-Fattah el-Sissi.

The Investigative Committee said the explosive device rigged with shrapnel went off in the school lunchroom and Sergei Melikov, a deputy chief of the Russian National Guard, said it was homemade. Officials later found a second explosive device and destroyed it.

Guns are tightly restricted in Russia. Civilians can own only hunting rifles and smooth-bore shotguns and must undergo significant background checks. Roslyakov had only recently received a permit to own a shotgun and bought 150 cartridges just a few days ago, according to local officials.

Aksyonov, the regional leader in Crimea, said the gunman had been described as a shy boy who had no conflicts.

"He wasn't aggressive, he was rather timid," Aksyonov said, speculating that Roslyakov might have "watched some movies" that inspired him to go on the shooting spree.

Some Russian news reports said the shooter had left his backpack containing the explosive device in the cafeteria and remotely detonated it before he started shooting.

"I heard an explosion and saw glass shards and window frames falling down," student Roman Voitenko said in remarks broadcast on Russian state television.

Another student, Semyon Gavrilov, said he had fallen asleep during a lecture and was awakened by the sound of shooting. He looked around and saw a young man shooting at people, he said.

"I locked the door, hoping he wouldn't hear me," Gavrilov told the Komsomolskaya Pravda newspaper.

He said police arrived about 10 minutes later to evacuate people and he saw dead bodies on the floor and charred walls.

Russia has seen several violent attacks by students in recent years, but none of them were even remotely as brutal as the Kerch ra

What do we know about the alleged gunman?

Vladislav Roslyakov had a weapons permit, said Sergey Aksenov, the President of Crimea, on  “Russia 24”.

Roselyakov's parents are divorced and live with his mother and he was a shy young man

Roselyakov, 18, was a senior at Kirch Polytechnic College, where he joined school in 2015, according to the Russian Federal Investigation Commission.

"He was a shy young man who spoke to almost no one, and had all his accounts in the social media deleted for some time."

Roselyakov's parents are divorced and live with his mother, who works as a nurse in a local oncology clinic. Mach later reported that police had detained Roselyakov's father for questioning.

Roselikov was found dead on the second floor of the main building of the college. According to Aksyonov, he was called the young man himself.

A Friend Said Roslyakov Had ‘Hinted’ That He Would Take Revenge on the College

Speaking to Russian broadcaster RBC, a friend of Roslyakov said that the suspect “hated the technical school very much because of the evil teachers, he hinted that he would take revenge on them.” Roslyakov was a resident of Kerch.
