Elvira Pimentel was 43 when she and her 17-year-old son, Elvis Sanchez, were found shot to death at 3964 Washington Street in Boston on August 7, 2011. The Office of the Chief Medical Examiner ruled both deaths homicides after the Boston Police Department responded and pronounced them deceased at the scene.

Investigators linked the double slaying to Sanchez’s recent involvement with the justice system. Sanchez had been subpoenaed to testify before a grand jury in the investigation of the July shooting death of 23-year-old Wilfredo Martinez in a housing development near Sanchez’s Roslindale home. Suffolk County prosecutors said Sanchez was not a cooperating witness but had been brought to court in hope he would testify; it is unclear what, if anything, he told authorities. Officials noted the possibility the murders were intended as witness intimidation.

No arrests or publicly identified suspects have been announced, and the Boston Police Department continues to list the case as open and unsolved. Did anyone in the community know Elvira or Elvis or have information about what happened that night?
