On the evening of August 22, 2012, a man forced his way into a Chartsey Street home in Kettering, Maryland, and went directly to 17-year-old Amber Stanley’s bedroom. Amber, an honor student at Charles H. Flowers High School who hoped to study medicine at Harvard, was shot multiple times while in bed and died; four other people in the house were unharmed and nothing was reported stolen.

Investigators say the attack may not have been random and that the gunman might have been seeking Amber’s foster sister, who had recently been sexually assaulted and allegedly posted a threat on social media directed at her attacker. Police have interviewed nearly 100 people and identified a person of interest — currently incarcerated on unrelated charges — after DNA from an altercation involving the foster sister reportedly pointed to him. Authorities say they do not yet have enough evidence to charge anyone and the case remains open.

Does anyone who knew Amber, her family, or who lived on Chartsey Street in 2012 have information that could help bring answers?
