good evening. thank you for joining us. tonight new details in a bizarre case of romantic boating trip

gone horribly wrong. did a young woman lose her fiance in a tragic accident or was it murder? we have obtained video of her interrogation that may help answer those questions. >> reporter: in this newly released 911, her voice sound like a frantic call for help. could it be a cold-blooded cover-up. >> reporter: police and prosecutors say the drowning of graswald's fiance was no accident. it was murder. she has been in jail on $9 million bond awaiting trial. but tonight abc news has obtained the interrogation video which attorneys believe could help set her free. she made a desperate call to 911 after a romantic kayaking trip

when her trip turned tragic. it was a warm april evening. but the river deceptively 46 degrees, cold enough to kill and it does. with no life jacket, no protective dry suit her fiance vincent who had been drinking sinks into the bone chilling current. and then vincent villafor disappears. his body not resurfacing until weeks later. while he was still missing angeliqa spoke with the station. >> he was trying to figure out how to paddle the waves. they were getting crazy. and -- and then i just saw him flip. i saw him struggling a little

bit. >> reporter: police soon becoming suspicious of her. she didn't seem like the grief stricken girlfriend on social media to authorities. changing her facebook photo with the caption if only i could have paddled harder. uploading the seemingly lighthearted video of her returning to the place where she met villafor when he was still missing. >> what a beautiful day. driving at the yacht club. >> she made statements that implicated herself in the crime. enough that have reasonable cause. >> reporter: after questioning her nearly 12 hours, police arrest her charging her with second degree murder. insisting she confess during the interrogation. >> reporter: in this interrogation video obtained by abc news, graswald continually denies killing her fiance. >> i didn't want to kill him. >> reporter: cooped up overnight stretching in yoga poses, she admits to police the relationship with vincent did

take a toll on her. >> he pushed for sexual, sexual stuff. >> he always wanted sex. always wanted you to do sexual things. >> he wanted threesomes, foursomes. everything. and i was just not ready. >> she is 35. vincent was 46. though he was demanding and often jealous. she still want aid life with him and kconsidered his death a tragic accident. >> i wanted to have kids with him. and get married and live happily ever after. he was driving me crazy for a long time. i didn't want to kill him or anything look that. >> did you want him gone? isn't that what you said? >> i agree. i still wanted kid with him though. >> she admits she may have tampered with the paddle and removed the drain plug on his kayak weeks earlier but insists it wasn't part of a plot to kill him. >> why didn't you have the plug in there? >> he didn't have it because. i guess i had it. >> reporter: at time she

expresses relief that he is dead. which police and prosecutors used to make the case against her. >> did you intentionally take that plug out because you wanted to -- >> could be. >> when you watched him in the water, was a part of you saying, my worries are gone away now? were you almost -- >> euphoric? >> euphoric that he was going to be gone? >> there is no question she would have been much better off legally if she had said not going to answer your questions. i want to talk to a lawyer. >> reporter: her lawyers say she struggles with english and cultural differences. but even so in the video she never says she was trying to kill him. >> a confession would be her saying, i did it. i killed him. and incriminating statement is, i'm relieved that he's gone.

those are two very different things. >> reporter: experts tell abc news, a missing drain plug would not cause a kayak to sink even in rough waters. >> she set out to kill him via a drain plug in my mind is ridiculous. i don't, i don't see that as beg plausible at all. if she wanted to kill him by kayak, all she would have had to have done is basically capsized his boat and paddle away. >> reporter: she was indicted for murder and manslaughter has been in jail since april. defense attorneys say her defense will come down to common sense. >> i think that we're getting more of the discovery. and we are, now we can actually listen to the interrogation and see it. i think that you, know, curious, rational, intelligent people all come to the same conclusion. that is that she is not guilty. >> reporter: those who know her tell us they're shocked by the allegations. >> she is a very sweet girl as far as, as far as i have known. very energetic. very happy-go-lucky. you know, just a really nice

person. >> it is this sunny personality in the days after the tragedy that graswald's lawyers say have led to unfair public trial. >> they try to paint her as a murderer. in fact she was a fiance who was very much love and now the victim of a tragedy. we are trying to avoid her being the victim of a second tragedy. >> next, why would a famous athlete seek out a double life as a las vegas escort? golden girl gone wild, susie faber hamilton opens up. >> and model mogus chrissy tiegen and tyra banks on the set of their show. and what if this happened again? i was given warfarin in the hospital but i wondered if this was the right treatment for me. then my doctor told me about eliquis. eliquis treats dvt and pe blood clots

and reduces the risk of them happening again. not only does eliquis treat dvt and pe blood clots, but eliquis also had significantly less major bleeding than the standard treatment. knowing eliquis had both... turned around my thinking. don't stop eliquis unless your doctor tells you to. eliquis can cause serious and in rare cases fatal bleeding. don't take eliquis if you have an artificial heart valve or abnormal bleeding. if you had a spinal injection while on eliquis call your doctor right away if you have tingling, numbness, or muscle weakness. while taking eliquis, you may bruise more easily... and it may take longer than usual for bleeding to stop. seek immediate medical care for sudden signs of bleeding, like unusual bruising. eliquis may increase your bleeding risk if you take certain medicines. tell your doctor about all planned medical or dental procedures. eliquis treats dvt & pe blood clots. plus had less major bleeding. both made switching to eliquis right for me. ask your doctor if it's right for you. susie.

awe thought was that lightbulb moment in my head. wow, well, why shouldn't i get paid for sex? >> reporter: did you run this by mark? >> i had talked to him. all he thinks is she wants to just sample this, she'll do it once. she'll be done. >> mark, i don't know how anybody can understand how you didn't get up and say i am leaving you this is crazy. >> sometimes i wonder that too to be honest. it's what i did though. i tuned out. you live your life. i live my life. >> reporter: very quickly you begin working under the pseudonym of kelly lundy. >> yes. >> reporter: she advertises her services with these alluring photos. her price $600 an hour. >> reporter: were you worried someone was going to recognize you and figure out you were susie faber hamilton. >> i was completely delusional. whatever it took, whatever risk i was going to do it. >> reporter: any gambler will tell you luck can't last forever. >> i'm waiting for the elevator.
