On the evening of August 7, 2011, 17-year-old Elvis Sanchez and his mother, Elvira Pimentel, were fatally shot at 3964 Washington Street in Roslindale. Boston police found Sanchez after a call for a person shot; he was pronounced dead and the Office of the Chief Medical Examiner ruled his death a homicide.

Investigators looked into possible motives including Sanchez’s recent subpoena to testify before a grand jury about the July 2011 murder of 23-year-old Wilfredo Martinez in a nearby housing development. The Suffolk District Attorney’s Office said Sanchez was not considered a cooperating witness, leaving the motive unclear.

No arrests or suspects have been publicly identified and the case remains an open, unsolved homicide. If anyone knew Elvis or Elvira or has information about that night, please come forward.
