A school building that was supposed to soon be filled with children preparing for a new academic year became the scene of a deadly investigation instead. Days before students were scheduled to return, two custodians were found shot inside Chicago’s Mark Twain Elementary School, leaving a community searching for answers about what happened behind the school’s closed doors.
The shooting happened on August 10 inside the Garfield Ridge Elementary School, where police found a 48-year-old woman and a 63-year-old man suffering from gunshot wounds. Both were taken to Christ Medical Center in critical condition but later died. Police recovered a weapon at the scene, but investigators have not publicly released a complete account of what led to the deaths.
The case has drawn attention because of the unusual setting. No students were inside the building at the time, and classes were not scheduled to begin until August 24. Instead of a student emergency, authorities are investigating a deadly incident involving two employees who worked inside the school.
A School Preparing for a New Year Becomes a Crime Scene
Chicago police responded to Mark Twain Elementary, located in the 5100 block of South Lotus Avenue, after receiving reports of a shooting. Officers arrived at approximately 3:40 p.m. and found the two custodians unresponsive inside the building.
Authorities said each person had suffered a single gunshot wound to the head. The victims were transported to Christ Medical Center while emergency crews attempted to save them, but both were later pronounced dead.
The identities of the two custodians had not been publicly released in the reports reviewed. SEIU Local 73, the union representing Chicago Public Schools custodial employees, confirmed that both victims worked as custodians at Mark Twain Elementary.
The timing added another layer of concern for families. The school year had not yet started, meaning the building was not filled with students, teachers, or parents. Instead, custodial workers were among the employees preparing the campus before children returned.
Principal Matthew Moline informed families that shots had been fired inside the school and acknowledged the impact on the school community.
“I am sorry to share that members of our school community were impacted,” Moline said.
He added that the school would provide additional information as the investigation continued and emphasized that officials were taking the situation seriously.
Investigators Are Piecing Together What Happened Inside the Building
The details surrounding the shooting remain limited as Chicago police continue their investigation.
The Chicago Sun-Times reported that preliminary police radio transmissions described the incident as an apparent murder-suicide and indicated that a disagreement between the two custodians may have preceded the shooting. However, those details came from early dispatch information and have not been fully confirmed through a public police statement outlining the sequence of events.
WTTW also reported that a police document cited by the Sun-Times identified the older custodian as the alleged shooter and suggested he may have been upset about an anticipated workplace relocation. That detail has not been independently confirmed as an official finding by investigators.
Police have not publicly explained:
- What relationship the two employees had with each other.
- What specifically happened before the shooting.
- Whether there were previous workplace concerns.
- How the weapon entered the school.
Those unanswered questions remain central to the investigation.
The recovered weapon is one of the few confirmed pieces of evidence publicly disclosed so far. Authorities have not announced charges, released additional forensic details, or provided a final determination about the circumstances of the deaths.

The Tragedy Raises Questions About Safety Beyond the Classroom
The shooting has reopened conversations about safety inside school buildings, especially as families prepare to send children back to classrooms.
Parents said the incident was especially unsettling because it happened inside the school building where their children would soon spend their days. Felicia Puga, whose daughter is entering second grade, told local reporters she was struggling with the idea of sending her child back.
“How are we supposed to send our kids to school knowing something like this could happen potentially again?” Puga said.
She said the situation left her reconsidering her family’s plans, adding that she was even thinking about other school options, although her family was not within another school’s attendance boundary.
While the shooting happened inside a school building, authorities have not described it as an attack targeting students or a traditional school shooting involving children. Preliminary reports instead point toward a possible workplace dispute involving two adult employees.
But how prepared are schools for violence between employees inside their own buildings?
The Bureau of Labor Statistics (BLS) recorded 3,300 nonfatal workplace violence cases in the private educational services industry during 2021–2022 that resulted in days away from work, job transfer, or work restrictions. The rate was 8.4 cases per 10,000 full-time workers.
Most reported cases involved serious enough injuries or incidents to affect an employee’s ability to work. Of those 3,300 cases:
- 2,560 cases (77.6%) resulted in days away from work.
- 740 cases (22.4%) resulted in job transfer or work restrictions.
However, national data don’t provide a specific count of fatal employee-on-employee shootings involving school custodians.

A Community Waits for Answers Before Students Return
For families connected to Mark Twain Elementary, the immediate concern is mourning two members of the school community while waiting for more information.
Trumaine Reeves, executive vice president of SEIU Local 73, said the focus should remain on the victims and their families.
“The only facts we know right now are that two families have lost a loved one and our prayers are with their families, and the staff, students, and families at Mark Twain Elementary School,” Reeves said.
Ald. Silvana Tabares, whose ward includes the Garfield Ridge neighborhood, said police described the incident as isolated and said there was no ongoing threat to the public.
Still, questions remain about how a workplace conflict inside a school escalated into a deadly confrontation.
As investigators continue reviewing evidence, the school community is left preparing for a difficult return. The first day of classes may bring students back through the doors of Mark Twain Elementary, but the memory of what happened inside those walls will remain with the staff, families, and neighborhood for much longer.
