Sally Heet was 35 when she was found murdered in her Washington, D.C. condominium in the spring of 1986. She left her Capitol Hill office on April 16 and returned to The Dorset, about six blocks away; that evening was the last time she was seen alive. The next morning her stepbrother and a colleague discovered her body in a blood-stained apartment; she had been stabbed multiple times.

Investigators reported no signs of forced entry to the secured building, and her mailbox was found open with the mail still inside, suggesting she may have known her attacker or been ambushed near the mailbox. Police pursued many leads and questioned numerous people. About three months into the inquiry, attention centered on an unidentified man who knew Sally and her building; he reportedly failed a polygraph and was believed by police to be responsible, but no charges were filed and he was not publicly identified.

The case remains unsolved, and a reward is still offered for information leading to an arrest and conviction. If anyone knew Sally, saw her on April 16, 1986, or has information about people who had access to The Dorset then, please come forward.
