Police in Washington, DC on Monday released a photo of the knife used by the suspect in Friday’s deadly ramming attack at a US Capitol checkpoint that left one officer dead and another officer injured.
The Metropolitan Police Department said its detectives, along with the United States Capitol Police (USCP) and the FBI, are investigating the attack as a homicide.
Officer William Evans, an 18-year veteran of the force, died Friday after the driver hit the barricade near the Capitol at around 1 p.m. last Friday. The driver, identified as Noah Green, 25, crashed into officers and the barrier, then exited the car armed with a knife and charged another officer before the officer fatally shot him, authorities said.
The photo released by police on Monday shows the wooden-handled knife lying on the ground next to an evidence marker.

DC Fire and EMS personnel responded to the scene and transported the suspect and the injured USCP second officer to a hospital for treatment.
The suspect, later identified as 25-year-old Noah Green, was pronounced dead at the hospital. The second officer who was injured was later released from the hospital.
In the chaotic moments after the attack, law enforcement officers initially believed that the suspect, who was seen on surveillance video lashing out at officers with a knife, could have stabbed Evans, but that was not the case.
The investigation is ongoing, but there is no indication that Evans was stabbed, stabbed or shot, a U.S. Capitol Police official said.
Investigators are increasingly focusing on Green’s mental health as they work to identify any motive for the attack. Investigators learned that the suspect had been suffering from delusions, paranoia and suicidal thoughts, according to the official.

In online posts since he was removed, Green described being under the control of government thinking and said they were watching him. He described himself as a follower of the Nation of Islam and its longtime leader, Louis Farrakhan, and spoke of having had a difficult time when he leaned on his faith.
