Andrew Philip Kehoe (February 1, 1872 – May 18, 1927) was an American farmer and treasurer of his township school board, notable as a mass murderer for killing his wife, and 43 other people (including 38 children), and injuring 58 people by setting off bombs in the Bath School Disaster on May 18, 1927. He committed suicide near the school by detonating dynamite in his truck, causing an explosion which killed several other people and wounded more. He had earlier set off incendiary devices in his house and farm, destroying all the buildings, as well as two horses and other animals.
Early life and education 
Kehoe was born in Tecumseh, Michigan, among the younger of a family of 13 children. His parents were Philip Kehoe (1833-1915) and Mary (McGovern) Kehoe (1835-1890). His mother died when he was five, and his father remarried; reportedly, Kehoe often argued with his stepmother. When Kehoe was 14 the family's stove exploded as she was attempting to light it. The oil fuel soaked her, and she caught fire. He watched his stepmother burn for a few moments before throwing water from a bucket on her; due to the oil-based nature of the fire, the water exacerbated the flames. She later died from her injuries. Allegations were made that the stove had been tampered with.
Kehoe attended Tecumseh High School and Michigan State College (later Michigan State University), where he studied electrical engineering. There he met his future wife, Ellen "Nellie" Price, the daughter of a wealthy Lansing family.
Marriage and family 
After his return to Michigan, he married Nellie Price in 1912, when he was 40, considered at the time a late age for a first marriage. They were both Roman Catholic and had no children. They moved around until 1919, when the couple bought a 185-acre farm outside the village of Bath from Nellie's aunt for $12,000. He paid $6,000 in cash and took out a $6,000 mortgage.
Kehoe was regarded by his neighbors as a highly intelligent man who grew impatient and angry with those who disagreed with him. Neighbors recalled that Kehoe was always neat, dressed meticulously, and was known to change his shirt at midday or whenever it became even slightly dirty. Neighbors also recounted how Kehoe was cruel to his farm animals, having once beaten a horse to death.
At first the Kehoes belonged to the Catholic church in Bath, but he refused to pay the church's parish assessment of members, and prevented his wife from attending.
Kehoe's neighbors thought he preferred mechanical tinkering to farming. His neighbor M.J. "Monty" Ellsworth wrote in his account of the disaster,
He never farmed it as other farmers do and he tried to do everything with his tractor. He was in the height of his glory when fixing machinery or tinkering. He was always trying new methods in his work, for instance, hitching two mowers behind his tractor. This method did not work at different times and he would just leave the hay standing. He also put four sections of drag and two rollers at once behind his tractor. He spent so much time tinkering that he didn't prosper.
Bath Consolidated School administration 
With a reputation for thrift, Kehoe was elected treasurer of the Bath Consolidated School board in 1924. While on the board, Kehoe fought for lower taxes and was often at cross purposes with other board members, voting against them and calling for adjournment when he didn't get his way. He repeatedly accused superintendent Emory Huyck of financial mismanagement.
While on the school board, Kehoe was appointed as the Bath Township Clerk in 1925 for a short period. In the spring 1926 election, he was defeated for the position, and was angered by his public defeat. His neighbor Ellsworth thought Kehoe started planning his "murderous revenge" against the community at that time. His neighbor A. McMullen noticed that Kehoe stopped working altogether on his farm in his last year, and thought he might be planning suicide.
During this time, Nellie Kehoe was chronically ill with tuberculosis, and had frequent hospital stays. At the time, before antibiotics, there was no effective treatment or cure for the disease. By the time of the Bath School disaster, Kehoe had ceased making mortgage and homeowner's insurance payments. The mortgage lender had begun foreclosure proceedings against the farm.
Bath School disaster 
The Bath School disaster is the name given to three explosions detonated by Kehoe on May 18, 1927 in Bath Township, Michigan, which killed 45 people (including Kehoe) and injured at least 58. Most of the victims were children in the second to sixth grades (7–12 years of age) attending the Bath Consolidated School. Their deaths constitute the deadliest act of mass murder in a school in U.S. history.
Between May 16, when she returned home from a hospital stay, and the morning of May 18, Kehoe killed his wife. He moved her body to a farm building before setting off incendiary explosions in their house and farm buildings. About the same time, he had arranged for an explosion, detonated by a timer, in the north wing of the school building. It killed many of the children and the few adults inside. Kehoe had set a timed detonator to ignite dynamite and hundreds of pounds of pyrotol at the school, which he had secretly bought and planted in the basement of both wings over the course of many months. The second 500 pounds of explosive, in the south wing, did not detonate, so part of the school was not destroyed.
As rescuers started gathering at the school, Kehoe drove up, stopped, and detonated dynamite by shooting his rifle inside his shrapnel-filled truck, killing himself and the school superintendent, as well as killing and injuring several others, including a boy who had survived the school bomb. During the rescue efforts, searchers discovered an additional 500 pounds (230 kg) of unexploded dynamite and pyrotol planted throughout the basement of the school's south wing, connected to an alarm clock that was supposed to act as the detonator and set for the same time that morning of the two other explosions.
After the bombings, investigators found a wooden sign wired to the farm's fence with Kehoe's last message, "Criminals are made, not born," written on it.
When they were done taking an inventory of the Kehoes' estate, investigators estimated that, prior to its destruction, sale of the unused equipment and materials on the farm would have yielded enough money to pay off the Kehoes' mortgage.
One of his sisters claimed Kehoe's remains and arranged for burial without ceremony in an unmarked grave. The Price family claimed Nellie's remains and had her body buried in Lansing, under her maiden name.
