Title: O.K. Corral hearing and aftermath
Content:  It is not known who started shooting first. Accounts by both participants and eye-witnesses were contradictory. Those loyal to one side or the other told conflicting stories and independent eyewitnesses who did not know the participants by sight were unable to say for certain who shot first. All witnesses agreed that general firing almost immediately commenced. Most witnesses reported the first two shots were so close together that they could barely be distinguished. Some witnesses testified that Morgan and Doc fired across one another at Billy and Frank, respectively. Wyatt said that he and Billy Clanton had fired first, and Virgil confirmed that one of the

Title: Mortal Error
Content:  Donahue eventually decided that the bullet that struck Kennedy in the head had in fact been fired by United States Secret Service Special Agent George Warren Hickey Jr. (March 24, 1923–February 25, 2005) from an AR-15 rifle carried in the car immediately following the President's vehicle. The proposed series of events is as follows: After the first shot which hit the street was fired, Hickey turns completely around and acquires Oswald on the sixth floor of the school book depository building. His turned head is documented in an AP photograph by James Altgens. Hickey reaches for the AR-15 under the seat, releases the safety

Like many Dealey Plaza witnesses, the first shot she remembered hearing sounded like a firecracker to her. She said that this first shot hit President Kennedy because she saw the president immediately (and almost simultaneously) raise up both his arms and clench his fists in front of his throat as a result of the first shot that she remembered.

It is now a collector's item. The bodies were discovered by Brett Martin, a British ex-RAF pilot, who is a resident in France, while he was out riding his bicycle. He heard nothing of the shots. This might be because he was crossing the last river bridge just a few hundred metres from the murder location; the noise of the water easily masking the sound of gunfire. Al-Hilli's eldest daughter, seven-year-old Zainab, was the first victim he saw 
Title: Yountville shooting
Content:  A stand-off started at around 10:30 am when a gunman, later identified as Albert Wong, a 36-year-old U.S. Army veteran of the War in Afghanistan, entered the facility during a going away party. The first 911 call of the incident was received around 10:20 am, and by 10:22 am the dispatcher had named Wong as the perpetrator and that he was armed with a semi-automatic weapon and large quantities of ammunition. Wong initially released veterans and other staff members, holding only Jennifer Gonzales Shushereba, a psychologist, Jennifer Golick and Christine Lobber, the clinical and executive directors of Pathway Home respectively. Napa County deputies were some of the first to respond to the scene. At about 10 minutes after the initial 911 call Wong exchanged gunfire with Napa County Sheriff's Department Senior Deputy Steve Lombardi and then retreated into The Pathway Home building. After

The wounded receptionist, 61-year-old Shirley DeLucia, remained on the line for 39 minutes, despite her gunshot wound, and relayed information until she was rescued. She later recounted that the gunman had opened fire without saying anything. The gunman entered a classroom just off the main reception areas, where an ESL class was being given to students. Out of the 16 people in the room, Wong hit 13 of them, including the professor. He then took dozens of other students hostage. Police arrived within minutes of the 911 calls. Hearing the alarms, Wong committed suicide by shooting himself at 10:33 am, three minutes after he first opened fire. In all, Wong fired 99 rounds: 88 from a 9mm Beretta and 11 from a .45-caliber Beretta.

NBC cameraman Bob Brown was able to capture footage of the first few seconds of the shooting at the Otter, just before he himself was killed by the gunmen.

In 2005, Thomas's conclusions were rebutted in the same journal. Ralph Linsker and several members of the original NAS team reanalyzed the timings of the recordings and reaffirmed the earlier conclusion of the NAS report that the alleged shot sounds were recorded approximately one minute after the assassination. In 2010, D.B. Thomas challenged the 2005 Science & Justice article and restated his conclusion that there were at least two gunmen.
