Two National Guard members ambushed last week in a shooting blocks from the White House both suffered gunshot wounds to the head, according to new details released about the attack.

U.S. Army Spc. Sarah Beckstrom and U.S. Air Force Staff Sgt. Andrew Wolfe were on patrol near the intersection of 17th and I Streets NW in Washington "in full uniform" when shots rang out, according to an 8-page complaint filed by Metropolitan Police Department Detective Joshua Branson.

A photo taken from video surveillance at the scene of the Nov. 26 shooting shows the suspected gunman bending down next to Beckstrom and Wolfe after allegedly shooting them with a revolver, the charging document reviewed by USA TODAY said.

Wolfe, 24, of Martinsburg, West Virginia, remained "fighting for his life" after the shooting that fatally wounded Beckstrom of Summersville, West Virginia. She was 20. She survived just over a day after the violence.

The shooting suspect, 29-year-old Rahmanullah Lakanwal, attended his first court appearance in the Superior Court of the District of Columbia virtually from a hospital bed on Dec. 2.

He was charged with murder, assault with intent to kill and possession of a firearm during a violent crime, online court records reviewed by USA TODAY show.

Here's what to know about the latest information on the shooting.

Gunfire erupted at 2:13 p.m. while victims chatted with colleagues

Before the shooting rang out, footage recovered from a different area near the crime scene shows the defendant standing on the sidewalk outside the Farragut West Metro station for about one minute, according to court records.

In those visuals, the defendant appears to be glancing westbound at the intersection with 17th Street before running toward the area.

At approximately 2:13 p.m. ET, the charging documents said, two majors with the Army National Guard were talking with Beckstrom and Wolfe when gunfire erupted.

One of the witnesses alleged to officials that he saw the pair fall to the ground while simultaneously seeing the defendant shooting a gun and screaming, "Allahu Akbar!"

The Arabic phrase translates to “God is greatest” in English.

Beckstrom and Wolfe were "unresponsive and suffering from gunshot wounds to the head," before being transported to hospitals in critical condition, the complaint continued.

The witness, court papers continued, "immediately pulled his issued service weapon and engaged the defendant."

In a subsequent gunfight, the suspect was shot and fell to the ground.

The same witness said it appeared the defendant's firearm was empty, and another nearby person "immediately jumped on the defendant as (he) was attempting to reload," court records said.

Both witnesses and uniformed United States Secret Service officers who responded to the scene assisted in apprehending the suspect. According to the court document, Beckstrom was pronounced dead at the hospital on Nov. 27.

Autopsy: National Guard member killed by shot in back of the head

An autopsy conducted by Dr. Kristinza Giese with DC Office of the Medical Examiner confirmed Beckstrom died from a single gunshot wound to the back of the head.

Beckman's manner of death was ruled a homicide.
