Jacklyn Bass, a 49-year-old White woman known to neighbors as Jackie, was found critically injured in a stairwell at the Gates of Cipriano garden apartments along the 8500 block of Greenbelt Road in Greenbelt, Maryland, on the afternoon of September 21, 2010. Calls to 911 came in just after 2:30 p.m.; one caller reported a woman in a stairwell who looked badly injured and another reported a shooting, though officers were not certain whether gunshots had actually been heard. Bass was taken to a hospital but did not survive.

Detectives searched outward from the stairwell, towed a dark green Honda sedan believed to be hers for forensic testing, and interviewed nearby workers including tree trimmers. The complex reportedly had no security cameras and, because it happened during the workday, there were few residents around to witness anything. Police said the incident did not appear to be a robbery; neighbors reported she had been moving and described frequent, heated arguments suggesting domestic trouble, but no arrest or publicly named suspect was reported.

Does anyone who knew Jackie or who was near the Gates of Cipriano on September 21, 2010, have information that could help fill the gaps in her last hours?
