Milka Rivera, 39, was found shot to death in her Lawrence, Massachusetts apartment on September 5, 2011, alongside her children: 19-year-old daughter Sachary Montanez and 16-year-old son Max Montanez. All three victims were discovered in Max’s bedroom after police responded to a call around 2 a.m. Rivera, born in Guayama, Puerto Rico, worked at the Greater Lawrence Family Health Center; friends described her as a devoted mother and remembered the children as wonderful and promising — Sachary about to begin college and Max a tenth-grader and a football team guard at Greater Lawrence Technical High School.

Investigators identified the suspect as Jose Luis Tejeda, 40, Rivera’s live-in boyfriend of five or six years. According to accounts, Tejeda approached a neighbor, confessed to killing the family, and was arrested nearby without incident; police recovered a .357 Magnum revolver in the grass behind the apartment building. What details can anyone add about the family’s last days or the neighborhood that night?
