Shane Tamura: Investigation So Far

Police recovered Tamura's rifle, a Palmetto State Armory AR-15 assault rifle, which was smeared with blood.

A vehicle with Nevada plates registered to Tamura was found at the scene. Inside that vehicle, the police found a rifle case with rounds, a loaded revolver, ammunition and magazines, a backpack and medication prescribed to Tamura. The vehicle was searched by bomb squad and found to be clear of explosives.

The initial investigation shows Tamura's car travelled across country through Colorado on July 26 and Columbia New Jersey as recently as 4:24 pm on Monday. The vehicle entered New York city shortly after.

Tamura has a documented history of mental health issues, said the New York Police Commissioner Jessica Tisch during a press briefing.

The investigation so far reveals no criminal background. The motives are still under investigation. 

Manhattan Shooting: What, When, How

A man, armed with a long rifle and wearing a bullet-resistant vest, was seen walking into the 44-story Manhattan office building. He reportedly opened fire inside the Park Avenue skyscraper, which is just blocks away from Grand Central Station, Rockefeller Centre, and the Museum of Modern Art.

According to a press briefing by the New York Police Commissioner Jessica Tisch, the gunman first shot the NY Police Department Officer followed by a woman who took cover behind a pillar before proceeding through the lobby. He then shots a security guard, who was taking cover behind the security desk. One additional male was shot in the lobby.

"He then calls the elevator and goes up to the 33rd floor, which is Rudin Management and begins to walk the floor, firing rounds. One person was struck and killed on that floor. He then proceeds down the hallway and shoots himself in the chest," said Ms Tisch.

In total, the gunman shot five people, of whom four died, including a New York Police Department officer, Islam. The three civilians who died in the shooting have been identified as two males and a female. One male is severely injured and in a critical situation.

After opening fire, Tamura barricaded himself inside the skyscraper and was discovered dead from a self-inflicted gunshot wound on the 33rd floor, where other victims were found, sources told the New York Post.

Without giving many details, Ms Tisch shared, "At this time, the scene has been contained and the lone shooter has been neutralised."
