Chain of Custody & The Industrial Boiler Room Discovery
On October 29, 1996, maintenance workers inspecting an abandoned industrial warehouse facility situated on Lansing Street in the Tacony neighborhood of Northeast Philadelphia, Pennsylvania, discovered human skeletal remains inside a disused basement utility boiler room.
Philadelphia Police Department Homicide Unit detectives and death investigators from the Philadelphia Medical Examiner's Office processed the scene. The body was completely skeletonized, lying near an inactive commercial furnace. Taphonomic indicators suggested the remains had been in the structure for several months prior to discovery.
Forensic Anthropological Profile & Pathology
Examination at the Philadelphia Medical Examiner's Office determined the decedent was an adult Black male, estimated between 35 and 50 years of age, standing approximately 5 feet 7 inches to 5 feet 9 inches in height. Anthropologists noted evidence of past healed rib fractures and spinal degenerative wear.
No obvious traumatic blunt force cranial defects or gunshot wounds were identified on the dry bone elements. Personal effects recovered nearby included weathered denim trousers, work boots, and remnants of a dark jacket, but no identification or wallet was present. He was cataloged in NamUs as UP12702.
2023 Identification by DNA Doe Project
In 2022, Philadelphia Police cold case investigators partnered with the DNA Doe Project. Skeletal samples were sent to HudsonAlpha Discovery for high-density SNP microarray extraction.
Genealogists mapped family branches across Pennsylvania and Virginia. In 2023, after twenty-seven years of anonymity, investigators announced that Lansing Street John Doe was David Ubank Brown, born in 1954 and aged 42 at the time of his death. Family members confirmed David had vanished from his Philadelphia neighborhood in early 1996.
