Family and friends of the late Barbara Hamburg held a candlelight vigil in her honor at the First Congregational Church Saturday night.
Her family is still looking for answers. Hamburg was found dead outside her Madison home in March 2010. Investigators say she was beaten and stabbed. Police have not made any arrests in the case.
Hamburg's sister, Conway Beach, believes the more people know about Barbara's murder, the more likely someone will remember something about that day and call police. Barbara Hamburg's death is still under investigation.
Investigators ask anyone with information to call police.
