There are new details in the case of the Staten Island mother Sarai Sierra who traveled to Turkey alone and never came back.
Authorities say just days before her murder, the married mother of two told her landlord in Istanbul that she was single.
There are also allegations that Sierra had sex with a man in a bar bathroom. The man claims the sex was consensual.
Investigators say weeks before Sierra disappeared, her husband posted messages on Instagram about cheating and bad relationships.
