"Obviously what's been put forth in the media and by authorities is subject to further investigation and it's going to be tested at some point in a court of law," Honecker said. "The family and friends of Megan are supporting her tremendously. I think they realize if some of these allegations were in fact true this may have been a situation where she was fortunate."
As for now, he added, McAllister "will take this day by day and try to move forward with her life."
Clinical psychologist Kelly Sykes told "Good Morning America" that to be told that someone one loved is a murderer is not something anyone could easily accept.
"I would imagine the first thing you're feeling is denial, an unwillingness to accept the reality of what's being given to you," she said. "It turns your life upside down."
McAllister has stuck by Markoff from the beginning, starting with her e-mail to ABC News shortly after his arrest saying her fiance "could not hurt a fly."
The panties and restraints were found along with duct tape next to a hollowed-out copy of "Gray's Anatomy" that hid the semi-automatic weapon police believe was used to shoot Brisman April 14. Brisman had rented a room at the upscale Boston Copley Marriott from Monday April 13 through Wednesday April 15 to offer $200 massages "with hand relief."
Markoff, who has been dubbed the "Craigslist Killer," is charged with bashing Brisman's head in around 10:10 p.m. and shooting her three times at point-blank range.
He is currently in the psychiatric unit of Nashua Street jail, where he is monitored around-the-clock after he tried to strangle himself with shoelaces and tried to slice his wrists with a spoon he sharpened to a point using concrete in his cell, a law enforcement source said.
Last week, he told his parents, brother and sister-in-law during a jailhouse visit to "move to California and forget about him,'' another law enforcement source told ABC News.
"He said that there was a lot more to come out,'' the source said. "He has spent all of his time now sleeping and staring out the window at the news trucks."
Boston Police officials would not comment Wednesday on the number of panties found when homicide investigators executed a search warrant of Markoff's apartment after his arrest. Markoff was on his way to Foxwoods Resort Casino with fiancee Megan McAllister when he was arrested April 20.
Markoff is next due in court May 21.
McAllister's jailhouse visit came days after she broke her silence to say she would continue to stand by her man.
Before her jailhouse visit, McAllister released a statement in which she thanked friends and family for their support and expressed sympathy for "all of those afflicted by these events."
She said, "I also love my fiance, and I will continue to support him throughout this legal process."
McAllister added that she did not recognize the man she had seen in the media reports about Brisman's murder and the alleged attacks and robberies of two others, one in Boston and one in Warwick, R.I.
"What has been portrayed and leaked to the media is not the Philip Markoff that I know," she said in the statement. "To me and my family, he is a loving and caring person, and in the eyes of the law and the Constitution, he is innocent until proven guilty beyond a reasonable doubt.
