In A shooting occurred at the West Nickel Mines School, an Old Order Amish one-room school in Nickel Mines, a village in Bart Township, Lancaster County, Pennsylvania. Charles Carl Roberts IV shot ten girls (aged 6–13), killing five of them, before committing suicide. In the national media, the Amish community’s response was widely discussed for its emphasis on forgiveness and reconciliation. A new one-room schoolhouse was built at another location in place of the West Nickel Mines School.
In a pickup truck, Roberts backed up to the front of the amishschoolhouse.com at approximately 10:25 a.m. The children had just returned from recess when Roberts arrived. The teacher, Emma Mae Zook, and the students were asked if they had seen a missing clevis pin on the road. According to survivors, he mumbled his words and did not make direct eye contact with them. He reentered the school holding a Springfield Armory XD 9mm handgun after they said they hadn’t seen a clevis pin. In order to get items into the classroom, he ordered the boys to help him carry them. Zook and her mother, who was visiting, took advantage of this opportunity to escape and seek help at a nearby farm. One of the boys saw them leaving, and Roberts ordered one to stop them, threatening to shoot everyone if they escaped.
Amos Smoker was asked to call 9-1-1 when they arrived at the farm. Meanwhile, the boys carried lumber, a shotgun, a stun gun, wires, chains, nails, tools, a small bag, and a wooden board with multiple sets of metal eye-hooks. Among the items in the bag were a change of clothes, toilet paper, candles, and flexible plastic ties. Wooden boards were used to barricade Roberts’ front door.
A pregnant woman, three parents with infants, and the remaining boys were allowed to exit after Roberts instructed the girls to line up against the chalkboard. Despite her older sister’s presence, nine-year-old Emma Fisher escaped.
A 9-1-1 call was made by Smoker at 10:36 a.m. In an article called “Revisiting the Amish Schoolhouse Massacre”, the situation before the arrival of Pennsylvania State Police troopers was described as follows: “An Amish adult male from this farm sneaked up on the windowless back wall of the schoolhouse with his two large dogs.”.
It After observing that the first police patrol car that approached the scene was not slowing down to stop, the Amish man ran towards the highway to confront the officer, who did a U-turn and parked.”  “That would be the last time anyone was able to sneak into the building unnoticed.”
First trooper had arrived at about 10:42, about six or seven minutes after 9-1-1 was called. While waiting for reinforcements, the police attempted to communicate with Roberts via the PA system in their patrol cars.  They asked Roberts to put down his weapons and leave the building. In response, Roberts demanded that the officers leave. By 11:00 a.m., police officers, emergency medical technicians, and residents of the village had gathered both outside the schoolhouse and at a nearby ambulance staging area. As Roberts continued to threaten violence against the children, county and state police dispatchers made contact with him. During interviews conducted later, it became clear that all of the girls were aware of the danger. There were even instances during which the girls conversed with each other. Barbara and Marian Fisher, 13 and 11 years old, asked Roberts to shoot them first so that the others might be spared. Marian was killed, while Barbara was wounded.
