MATTHEWS, N.C. - It was a story that made national headlines.  Wachovia executive David Crespi stabbed his twin five-year-old girls to death in their Matthews home one Friday afternoon in 2006.

Then 45-years-old, Crespi had been on a cocktail of drugs, including an antibiotic, Ambien and Lunesta for sleep, Trazadone for anxiety and the newest addition: Prozac.

"From moment one, I thought what's the difference in our life? What could have propelled this change?  And the difference was, for us, seven days of Prozac," says David's wife, Kim Crespi.

She is now raising the couple's three other children and remains in the home where the girls were killed.  Crespi says, "The house did not kill the girls.  We know how they died, we know what happened.  We know it was the medication.  So I'm not afraid here.  I think it's sacred ground in many ways."

What happened, Crespi says, was a psychotic episode; a severe side effect of the drugs her husband was taking.  She calls the drugs "unpredictable."  "We don't trust prescriptions anymore.  We don't trust our doctors.  We did.  And I'm sorry to say that, but it's true," she says.

Crespi wants her husband released from prison, a goal that may seem unrealistic.  But she has found an ally in Canada's David Carmichael.  Carmichael strangled his 11-year-old son Ian in 2004 in a hotel room.  He says, "I remember every detail."  At the time, Carmichael was taking Paxil for depression.  He was judged "not criminally responsible" for the murder and today, is a free man.  He says, "I can tell you that even when I'm out in the public, people that are critical of me, people that feel I've come through a system and I should be punished, they'll never beat me up as much as I beat myself up for a long time."

Crespi is also no stranger to criticism and a community that is, at times, judgmental.  But for now, the California native has no intentions of leaving.  She says, "North Carolina holds us here because I'm not leaving without Dave."

FOX News @ Ten anchor Morgan Fogarty asked Crespi, "If David does get released from prison and comes home to live with you, will there ever be that thought in the back of your mind, could this happen again?" She answered, "No. Because I know what happened.  He's not going to take those drugs again." 
 
David Crespi is serving two consecutive life sentences for the deaths of his daughters, Tess and Sam. 

Kim Crespi and Carmichael are hosting a seminar about their experiences with prescription drugs.   The seminar is Thursday, October 11th.  It is free and open to the public.   It's at the South Charlotte Banquet Center, 9009 Bryant Farms Road, Charlotte, NC 28277.  Doors open at 7PM.
