PHILADELPHIA (CBS) — Investigators were at a Center City apartment looking for evidence connected to the gruesome discovery of a human torso found in the Schuylkill river Tuesday morning (see previous story).

Police have identified the victim as a man who had been reported missing.

Only CBS 3 was there as the Philadelphia Crime Scene unit first entered the second floor apartment at the 200 block of S. 11th Street near Walnut Street in Center City.

Police identify the victim as 40-year-old Frank Zarzycki of Northeast Philadelphia.

His dismembered torso was discovered Tuesday in the Schuylkill River near the Grays Ferry Bridge.

Investigators left the 11th Street apartment with bags containing possible evidence, as shocked neighbors looked on.

Police were looking for blood or DNA evidence that would indicate if Zarzycki was killed here, and if his body was dismembered here or someplace else.

CBS 3 found these flyers of Frank that were handed out near the apartment.

His family was looking for him.

He had been missing since last Monday and was last seen in this area near 11th and Walnut.

Police indicate Zarzycki had a planned meeting here. Sources indicate detectives are looking into the possibility the apartment may be linked to prostitution.

Investigators were able to identify the 40-year-old through tattoos on his torso.

No arrests have been made so far.
