What happened
José Luis Calva was arrested in Mexico City in 2007 after police discovered human remains in his apartment while investigating the disappearance of his girlfriend.
The investigation
The scene led investigators to examine whether Calva could be connected to other missing or murdered women. Media descriptions quickly focused on writings and evidence found in the apartment.
What the courts or investigators concluded
Calva died in custody before he could be tried, so allegations beyond the central homicide were never fully adjudicated.
Why the case remains significant
The case remains a cautionary example of how macabre evidence can produce sensational claims that exceed what a court has actually established.
