Sneak peek: The Monica Sementilli Affair | Forensic Files

She was incredibly charming. She was attractive. I don't even want to entertain why she
did what she did. You had a beautiful home. You didn't work. You had cleaning ladies. You'd
pool people. You had cars, money. You had it all. Monica Sementantilli. Homicide investigators say she conspired
to murder her husband. They said when they talked to her, she lied and lied. I was hearing about breakins. At the
time in that particular area, there were a lot of what they call knock-knock burglaries. I was hearing about home
invasion. It was assumed that it was a couple guys that had jumped the fence and it was a robbery.
What happened on the day of the murder? That night at about 5 something, I got a
text saying, "Come to my house. I need you." I get the phone and and I'm in disbelief saying, "What? What? What?"
Cuz I can't believe it. And it was uh Monica. She was crying and distraught and she
was saying they killed Fabio. Fabio Simon Tilly. Fabio was an executive in the beauty
business. Was a former hairdresser. My queen, he called her. He would come home, drop his bags, sweep her off her
feet, and dance with her. He was the love of her life and he loved his kids. It looked like a textbook breakin.
A robbery gone wrong. There was immense suspicion as to the explanation of a robbery. From my
perspective, didn't sound right. Didn't sound right. We're here to announce the arrest of two
individuals in connection with the murder of Fabio Simantilli. Over the past several months,
investigators have developed information and identified Robert Baker and Monica Simmenti, who is the wife of our
homicide victim, as responsible for his murder. Detectives say Monica Simontelli had
been having an affair. Her boyfriend was arrested and charged with murder, but so
is she. I'm like, you sure? There's no effing way. The boyfriend has been convicted. He has
been sentenced to life without parole. And Monica Santilly is on trial for murder. According to the prosecutor, she
was the one with all the information and intelligence, and she fed it to him. and
he was the executioner. The daughters she shared with Fabio are standing by her. We want to clearly
state that we will continue to stand by our mother as we have done for the last 6 years and we will fight for her
innocence. The defense is going to say there's no evidence that Monica Cementelli
conspired to kill her husband.
