The FBI has not found the fragment that pierced a Secret Service officer’s bulletproof vest at the White House Correspondents’ Dinner on Saturday, leaving investigators unable to say for certain whether the armed attacker shot the officer or how he was injured, according to two people briefed on the probe.

Law enforcement agents on the scene Saturday believe Cole Tomas Allen, the suspect who breached the dinner’s final checkpoint, fired his shotgun and struck the officer with buckshot from his weapon, according to one of the people, who asked not to be named due to the sensitivity of the ongoing probe. A check of Allen’s shotgun showed that he discharged a shell but did not reload,Acting Attorney General Todd Blanche told reporters Monday.

But a mystery surrounds Allen’s use of his weapon — and the scuffle and shooting just above the Washington Hilton ballroom, where President Donald Trump and many senior administration officials had gathered for the dinner.

Allen was charged on Monday with attempting toassassinate the presidentof the United States, as well as transportation of a firearm over state lines and discharge of a firearm during a crime of violence.

On Saturday, Allen sprinted through a final screening checkpoint just above an open stairway to the ballroom, prompting one Secret Service officer from the uniformed division to shoot five rounds at the fleeing man. Investigators collected the firearms of all Secret Service officers and agents on the scene and found no evidence that anyone else fired their weapons, one law enforcement official said.

Here are other new details MS NOW has learned about the incident:

“He didn’t dilly dally once he got there,” one person who saw the footage said. “He just immediately went for the checkpoint.”

The Secret Service does not require agents in stairwells of this public hotel when they are outside the magnetometer-screened perimeter of the dinner event.

The FBI declined to comment to MS NOW.

The ability of Allen to breach the final checkpoint at the Washington Hilton has raised alarm among top White House aides, even though no one was seriously injured and officers and agents were able to stop Allen before he reached the ballroom doors. The doors were also guarded by armed law enforcement officers and agents.
