A routine day at UNAM’s CCH Sur ended in panic and grief. A 16-year-old student was fatally stabbed, a staff member was wounded, and the suspected attacker jumped from a building while trying to flee. He survived with broken legs and is under police guard. Authorities opened a homicide investigation, and the campus suspended classes. Students gathered, angry and scared, asking fundamental questions about safety and protocols. The university stated that it will support families and review its procedures. The case is now in the hands of the prosecutors in Mexico City.

CCH Sur student killing

A deadly attack inside UNAM’s CCH Sur shattered a Monday afternoon. A 16-year-old student, identified as Jesús Israel “N,” was stabbed on campus. A worker who tried to intervene was wounded. The suspected attacker then ran, reached an upper floor, and jumped. He broke both legs and was taken to a hospital under police custody.

Prosecutors in Mexico City said they opened a homicide investigation. Their preliminary account sets the timeline around 1 p.m. The suspect was identified as Lex Ashton “N,” 19. Officials said he attempted to flee before leaping from a building. They are examining possible motives and social media posts tied to the incident.

What happened on campus

Witness reports and official statements describe a fast, chaotic scene. Students and staff were evacuated as emergency crews arrived. UNAM later confirmed that the 65-year-old injured worker was out of danger and had been discharged. The university contacted families to offer legal and psychological support. CCH Sur suspended classes until further notice.

The attack unfolded at the CCH Sur campus in Coyoacán. Local reporting notes the suspect wore dark clothing and had covered his face. Outlets also reported he had previously posted images of blades and other objects. Prosecutors and university officials have not yet given a definitive motive.

The investigation and the questions ahead

The prosecutor’s office is leading the case, with the suspect guarded in a hospital after fracturing both legs in the fall. Authorities say they are analyzing evidence and interviewing witnesses. UNAM pledged to review safety protocols across the campus system and to support those affected. Students are demanding clarity and concrete steps. CCH Sur student killing is now a test of trust and response.

Parents and classmates will want clear answers: how the weapon entered, whether prior warnings were missed, and how the emergency response worked. UNAM says it will cooperate with authorities and keep the community informed. For now, a family is grieving, a community is shaken, and a campus is quiet.
