Authorities have released surveillance images of a man being sought in connection with the strangling of a model in Philadelphia's affluent Main Line suburbs.
The body of 36-year-old Christina Carlin-Kraft was found Wednesday night in her apartment in Ardmore.
Her death has been ruled a homicide.
Authorities on Monday released video of a man authorities say had contact with the victim early that morning in Philadelphia.
They say he was also seen at the entrance to the subway station and may have used a ride-hailing service to get from Philadelphia to Ardmore.
Carlin-Kraft had just moved into the apartment last week.
Her modeling profile lists photo shoots for Vanity Fair, Victoria's Secret, Playboy and Maxim.
