In December 2010, Leslie, Adam Newman's attorney, came to Sharon Newman and Adam's motel room and announced that police already had the photo of the mystery couple in the freight elevator. Leslie said that at least police were investigating the possibility that Skye Lockhart Newman was alive and scamming Adam. Leslie hoped Adam might have a photo of Skye wearing the shoes and carrying the purse seen in the photo, but Adam said he did not. Sharon asked about Skye's perfume and Leslie confirmed that the bottle was listed on the inventory of police evidence.
Sharon excitedly suggested checking to see if Skye had ordered a replacement bottle of the rare perfume. Adam said he'd rather prove that Skye was alive. Leslie believed the district attorney would soon announce that Adam was no longer a person of interest because the evidence was weak. Leslie added that Skye had a vendetta against Adam and had previously faked her death. Leslie later returned to the jail and visited with Adam in the interrogation room. Leslie reported that Sharon had texted her from a remote area of an island. Sharon reported that she was at the post office where the perfume had been delivered.
Leslie told an anxious Adam that it might be a while before they heard more from Sharon. Adam berated himself for allowing Sharon to venture near Skye. Leslie explained that Sharon was determined, so they couldn't have stopped her. Adam replied, "Any hope of me having a life outside of prison is all in Sharon's hands now."
