On October 20, 2007, Miguel A. Perez, a 22-year-old from Boston, was shot and killed in what became one of the city's many unsolved homicides. His death, which took place in a year marked by rising gun violence in the area, has remained a mystery despite ongoing efforts by law enforcement to gather information. Perez's murder remains part of Boston's broader issue with violent crime, and authorities have urged the public to come forward with any details that could help resolve the case.
