This is the first picture of the gunman who stormed the Russian FSB security service in Moscow.
He was named as Yevgeny Manyurov, 39, a security guard from Podolsk, a suburb of Moscow but so far his motive remains unclear.
The shooter died in the Lubyanka attack which killed an FSB officer and wounded one civilian and four security service operatives.
Despite earlier suggestions of more than one attacker, the Russian authorities now believe Manyurov acted alone.
So far the Russian Investigative Committee - which has similar functions to the FBI - is not using terrorism laws to probe the armed assault on the FSB, the main Russian domestic security service once headed by Vladimir Putin.
The well-educated gunman lived with his mother and was an active member of an amateur shooting club, reported the BAZA news outlet which published the first picture of Manyurov.
Manyurovhad told his mother he was going to a shooting competition when he went to the FSB's main public reception office and opened fire.
Other pictures showed his body after he was gunned down by Russian special forces troops.
He had worked as a security guard registered with private agencies and studied at the Russian Academy of Justice.
He also completed courses at the prestigious Higher School of Economics in Moscow.
He earlier ran own consulting business, which he closed in 2015.
His interest in shooting competitions was recent.
In November he took third place in pistol competitions of the Moscow city shooting and sports club DOSAAF.
One month ago, he participated in a shooting match in memory of FSB hero Lieutenant Colonel Dmitry Razumovsky, who died during the terrorist school siege of Beslan in 2004, said reports early Friday in Moscow.
“He shot badly," said shooting club trainer Oleg Solovich. "To shoot well, you need to get involved in this for several years. He practiced with us for three months.”
He told Komsomolskaya Pravda: “He talked normally, but only went to classes in a long black coat with a hood.
“It was not even a raincoat…
“We suggested that he took off his outer clothing when he was shooting, but he said that he was so comfortable.”
He was licensed to carry weapons, confirmed Solovich.
Asked if the gunman was crazy, he said: “Well, wait, how crazy?
“After all, he had a rifle carbine with a 7.62 mm caliber with all the necessary documents, which means that earlier he had owned smooth-bore hunting weapons for five years.
“It turns out that the state completely trusted him.… on this basis, we taught him shooting.”
A criminal case was opened over an attempt on the life of a law enforcement officer.
Kommersant reported that this may be extended to terrorism laws as the investigation proceeds.
