Authorities have released surveillance images of a man being sought in connection with the strangling death of former Playboy model Christina Carlin-Kraft—who was found dead in her Philadelphia-area condominium August 22.

On Monday, officials released video of a man who they believe had contact with the victim in Philadelphia on the morning of the day she died.

In a press release, the Montgomery County district attorney’s office said that a person of interest was “captured on video surrounding the entrance to the SEPTA subway and 15th and Market Streets” in Philadelphia. Further, they believe he may have used a ridesharing service to get from Philadelphia to Ardmore.

As CrimeOnline previously reported, Carlin-Kraft was found dead in her upscale Ardmore condo last Wednesday, and her death was ruled a homicide. Police had previously been to the home four days earlier responding to a report of a burglary, though it isn’t clear if the reported robbery is connected to the woman’s death.

The victim had only moved into the condo days before being murdered, ABC 15 reports.

Anyone with information regarding the identity or whereabouts of the male person of interest or knowledge of the rideshare transport he may have used is urged to contact the Lower Merion Police Department at 610-649-1000 or the Montgomery County Detective Bureau at 610-278-3368.
