Killer Thinks He Got Away — But His Stupid Mistake on a Whiteboard Solves the Case

On August 26, 2011, 20-year-old Amanda Plasse was found dead inside her apartment in Chicopee, Massachusetts. What started as a frantic 911 call from her boyfriend quickly turned into a complex murder investigation full of dead ends and unanswered questions.

Detectives struggled for years until a crucial mistake by the killer surfaced. Rosa Roman, the perpetrator, had left behind incriminating evidence — including wearing the same shoes he committed the murder in and carelessly writing his own name on a whiteboard at the scene. These blunders ultimately led to his arrest and conviction.

Roman was sentenced to life in prison without the possibility of parole. The case serves as a striking example of how even the smallest, seemingly insignificant mistakes can bring down a killer.
