Osuna mutilated Romero’s face to create a “smile-like” expression by slicing both sides of his mouth.

Reports said a razor-style blade was used in the crime. Romero’s injuries were severe, with signs of torture before death. The discovery shocked many due to the negligence of staff at Corcoran State Prison that night.
Reported negligence by prison guards
Guards at Corcoran State Prison failed to stop a brutal crime. They reported both Jaime Osuna and Luis Romero as alive during routine checks. A sheet blocked their view of the cell, but they still marked everything as fine.

Psychological Profile of Jaime Osuna

He admitted to feeling joy in murder, comparing it to an addiction.
Such killers often have antisocial or borderline personality disorder. Experts say they enjoy control and violence without care for others’ pain. Osuna even said he would kill again if given the chance.
