Sonia Rivera was 48 when she was found behind a building on Washington Street in Hartford on the evening of September 27, 2012. She was partially unclothed and had suffered severe head trauma; a brick found nearby was believed to be the weapon. Rivera was taken to Hartford Hospital and died a few days later. The Chief Medical Examiner ruled her death a homicide from blunt force trauma to the head. Her family donated her organs.

The investigation saw major developments over the following years. In May 2014 authorities arrested 43-year-old Denzil Nurse, a convicted felon, after DNA evidence from the scene was linked to him; he was charged with murder. In 2016 a Superior Court judge dismissed the murder charge against Nurse after prosecutors said the DNA evidence relied on an outside consultant was not as conclusive as first thought. Nurse admitted to sexual contact with Rivera but denied killing her. Later in 2016 prosecutors charged 56-year-old Robert White, a registered sex offender already serving a long prison term for another murder, with murder with special circumstances, felony murder, and capital felony in connection with Rivera’s death.

Does anyone have information about Rivera’s last known movements or the scene behind the Washington Street building?
