Joshua Daywalt, 35, of Philadelphia was found dead in the Schuylkill River on February 7, 2025. Authorities determined he had been shot in the back of the head and ruled his death a homicide. Daywalt had a history of severe mental illness; his mother, Jennifer Daywalt, said he struggled with schizophrenia, developed multiple personalities, and had refused treatment.

After nearly three months of investigation, Philadelphia police arrested 61-year-old Roger Gosson in connection with the murder. Gosson, reported to be homeless, had been living inside the Green Lane Bridge in the Manayunk section. A search warrant executed at the bridge uncovered a multi-level encampment with an electrical hookup, a fully furnished tent, and a firearm. Daywalt was last seen alive near the Green Lane Bridge, and no other arrests have been announced.

If anyone knew Joshua, his movements that day, or observed activity around the Green Lane Bridge in early February, please come forward with what you know.
