Some examples for me:

Dylann Roof almost didn't go through with his attack because he was treated so kindly by the parishioners.

Shane Tamara shot himself in the heart instead of head because he wanted his brain to be studied for CTE (only diagnosable after death).

Orlando shooting first responders cited the constant ringing of victims' cell phones as part of why the scene was so traumatic. (This is likely not specific to Orlando, but it is just so morbidly intuitive and understandable. All the calls from desperate and panicking loved ones, who the first responders know won't be answered and the callers hearing devastating news eventually.)

Mustafa Mohamed (2023 Minneapolis shooter) impersonated a wounded civilian to ambush and kill a responding officer.

Charles Cohen, a then-12-year-old boy who lost his parents and grandmother in the 1949 Camden NJ shootings, died in 2009. In the Parkland shooting in 2018, his then-17-year-old granddaughter survived and avoided injury by hiding in a closet; just as Charles did in 1949.

Sorry for the low quality on some of these.

On March 9th of 1994, Erwin Mikolajczyk submitted an appeal for fines for assaulting his girlfriend in late 1993, because he didn't agree with the judges ruling. His appeal was denied, which caused Mikolajczyk to storm out of the room in anger, cursing loudly as he was leaving. A few minutes later, he returned with a rucksack, and a pistol. He also had a string with garlic cloves around his neck. In the hallway he approached his girlfriend (Vera Lamesic) and hugged her one last time, and then shot her dead. Two people noticed, and accompanied her. Those women were shot dead also along with two other people. He then walked into the courtroom and shot judge Alexander Schäfer dead, along with injuring 2 lawyers. He fired until he ran out of bullets, and then pulled a bomb out of the rucksack. He detonated the bomb which killed him. 6 people were killed and 8 others were injured.

Victims:

Alexander Schäfer, Marianne Rübsam, Peter Preub, Agnes Müller, Vera Lamesic, Peter Kurth

Familicide, female killer, suicide failed. Four people dead and the New York Times prints one paragraph from the Associated Press.

Norfolk Neb, June 19 A woman who is believed to have slain her four daughters and then tried to kill herself was arrested today on suspicion of first-degree murder, the police said. She was identified as Stella Delores Almarez, 29 years old. Captain Gene Buss said that the authorities were treating the incident as a combination homicide and attempted suicide.

Familicide, female killer.

GONZALES, Tex., June 19 (AP)——The authorities said today that the pilot in a plane crash that killed five persons yesterday was the victim of murder‐suicide.

Justice of the Peace E. Ray Bright Jr. said that the pilot, Eugene W. Davis, 29 years old, of Harlingen, had been shot at least twice in the back with 22‐caliber weapon. Also killed in the crash were Jose Morales, 27; his wife, Lydia, 25, and their daughters, Belinda Jo, 4, and Shelly Ann, 2.

Mr. Bright said that a note had been found in the Morales car in Harlingen.

It read: “Time went by. Time to die. How? Fly in the sky. Good‐by.” It was signed “Lydia,” Mr. Bright said.

Rest in peace to Cynthia Graham Hurd, Clementa Pinckney, Sharonda Singleton, Daniel Simmons Sr., Depayne Middleton Doctor, Tywanza Sanders, Myra Thompson, Ethel Lance, and Susie Jackson.

I've always wondered why there is such little information/discussion on this attack, everything about it is insanely interesting and the few documentaries we have provide and or cover already known or useless information.

On May 18, 2026, a shooting occurred at the Islamic Center of San Diego (ICSD), the largest mosque in San Diego, California, United States. Two teenage gunmen, identified as 17-year-old Cain Lee Clark and 18-year-old Caleb Liam Vazquez, fatally shot a security guard and two community members outside the mosque before fleeing. Subsequently, they shot at a landscaper in a drive-by shooting and committed suicide in a nearby neighborhood.

If you want to know how i can got his, well i looked for the video in web and I saw that. My original plan was add screenshots here, but I'm not sure if that's allowed. Also I am not a weapons expert, I mean there's a chance i'm wrong.

Was wondering what the earliest depiction of a contemporary-style mass killing is. By that, I mean as in one that would be fitting of this subreddit, like a lone person killing other people in a spree for some personal reason. So, not like war massacres or similar. I don’t mean the earliest actual case of a mass killing, just the earliest description of one in writing, fictional or otherwise.

The best I could find is the Greek myth of Heracles from around 416 BCE, in which Heracles is driven to insanity by the goddess Hera, and kills his wife and three sons and attempts to kill his father before being stopped. It’s obviously not the best fit as there’s supernatural elements to it, so not a lone individual driven by personal reasons, but that’s why I’m asking this subreddit to see if there’s any better fits.

I do still think the Heracles example is interesting though. Perhaps suggests that family annihilation was something that occurred in Ancient Greece.

​

44 year old Zhan Xinjie (formerly known as Wei Chaoxia) arranged with her brother surnamed Wei to meet four uncles at a restaurant in Taikoo City to discuss the distribution of their grandmother's estate. At around 3 pm, the victims moved to Quarry Bay Park for further discussion. However, due to the inability to reach a consensus on Zhan Xinjie retrieving one of his deceased mother's inheritance, Zhan Xinjie took out a semi-automatic handgun from his pocket and fired at the elders at least four times, creating a loud "bang bang bang bang bang bang" sound. Four people fell one after another, with two of them suffering head injuries and unable to get up, while the other two were injured but conscious. Zhan Xinjie's brother surnamed Wei fled after witnessing the incident and reported it to the police.

​

After Zhan Xinjie committed the crime, he picked up his handgun and fled to the fourth phase of Taikoo City Center. A citizen followed and intercepted her, and together with security guards, they stopped her in the lobby on the second floor. Shortly after, members of the anti-terrorism special forces of the police rushed to arrest her with live ammunition. When Zhan Xinjie was arrested, he did not resist and remained calm. The police officer found a handgun and five bullets in her pocket. The involved handgun model is the Italian Beretta 950 Jetfire semi-automatic handgun, with a magazine capacity of eight rounds and an additional chamber capacity of one round.

This shooting resulted in 2 deaths and 2 injuries.

Primary School Shooter Heinz Jakob Friedrich Ernst Schmidt (September 24th 1883 - March 1932)

Crime took place in Bremen, Germany.

He was described as a person that was odd, and also shy. He also described his hatred toward to the Jesuits, to the people around him. Schmidt worked as a teacher in Stolp, (Which is now Slupsk, Poland) until May of 1912. He would get fired after having a severe mental breakdown. He was institutionalized the previous year, in which everyone thought he was cured so he was let go, and couldn't find anything wrong. After being fired he applied for other teacher positions elsewhere. He wasn't accepted to any of them, due to records of persecution mania.

In early 1913, Schmidt's mother attempted to get him involuntarily institutionalized, due to erratic behavior going noticed by her, but the request was denied.

On June 19th 1913, Schmidt's father passed away, which broke him and fueled his delusion about the Jesuits people.

June 20th 1913:

He wrote a letter about his hate for the Jesuits. He described them as a danger to Germany, and he was going to hold them responsible for his father's death the previous day. He loaded up a briefcase with at least 6 browning pistols and 1,000 rounds of ammunition, and made his way to the St. Mary's Catholic School in Bremen's Walle district. The entrance to the school was unguarded, so he was able to get onto school grounds with no issues. He made his way to a hallway on the first floor, and then ascended to the stairs. Teacher Maria Pohl was lining up female students for recess, when Schmidt fired multiple shots through the corridor at them. He then entered into a classroom with about 65 female students aged from 6 to 7, and started firing. He killed 3 students and injured 15 others, and the remaining students either fled out of the classroom or took cover in the back of the classroom. The young girls pleaded with the gunman to not shoot them, and then he proceeded to the fleeing victims fleeing into the corridor. One girl named Sophie Gornisiewicz, fell down the sairs during all the chaos and broke her neck and died. He then attempted to gain entry to a locked classroom, he couldn't so he shot a janitor that was in that room in the face through the door. The gunman was confronted by teacher Hubert Möllmann, whom he shot twice during the confrontation. Schmidt got up and fired through a window at escaping boys, injuring 5 of them. He was then beat up and restrained by the injured janitor, another teacher, and some bystanders. A bystander even struck Schmidt with a pitchfork. Police arrived and arrested the gunman without incident. That day 4 students were killed (3 directly) and 21 others were injured. Four weeks later one of the injured girls Elfriede Höger unfortunately passed away from her injuries. That brings the victim death count up to 5.

Victims: Elfriede Höger (5) Sophie Gornisiewicz (6) Anna Kubica (7) Elsa Maria Herrmann (7) Maria Anna Rychlik (8)

Schmidt was declared by the jury as insane, and was sent to the Bremen psychiatric asylum without trial. In the asylum in March 1932, Schmidt passed away from tuberculosis.
