Transcript for 'Black Widow' Faces New Charges for Allegedly Trying to Poison Husband
Luck. Ron claiborne, thank you. The woman who earned the nickname black widow is facing fresh charges. She will be in court next week, charged with attempted murder for allegedly trying to poison her husband. This from a woman who had previous marriages end in death and who actually did time for killing one of those husbands. Abc's john schriffen is here with more on this. Reporter: Bizarre doesn't begin to describe this story. According to reports out of canada, reportsay her latest husband new about her questionable past and decided to marry her anyway. But in court on friday, prosecutors decided to use her criminal history against her, trying to convince the judge not to grant bail and keep her behind bars. Hard to believe this 77-year-old woman, shielding her face from cameras, is a convicted killer who canadian authorities say tried to strike again. Melissa weeks, also known as the internet black widow, honeymooned with her latest husband in nova scotia when he became ill. At the hospital, doctors found a sedative drug in his body and became suspicious. I think it had more to do with the way mrs. Weeks was dealing with the medical emergency of her husband or not really dealing with the medical emergency of her husband more than anything. Reporter: After large amounts of primgs prescription drugs were found in her home and vehicle, weeks was arrested and charged with murder for allegedly trying to poison her husband. Despite week's request to be released, prosecutors say it is likely she will remain in custody. In this case, that's very significant, given her fraud history. And the various identities that she's had. Reporter: This is not the first time people have heard of the black widow. We heard about her when she was in florida. We read up some on that at that time. But it was just a -- it's just unbelievable. Reporter: But ex-boyfriend, alex, wasn't surprised when he heard weeks was in court because he claims she tried to poison him back when the two met in 2005. I had to go to sleep. If I had to get up to go to the bathroom or something, that's when I would get up. And I'd fall over. Reporter: Weeks was not convicted for allegedly poisoning him. But was arrested for wiping out about $20,000 from his bank account. Back in 1991, she was convicted of killing her then-husband gordon stewart, after drugging and running him over with her car, not once, but twice. She was sentenced to six years in prison. But only served two. Now, weeks could face up to 14 years in prison for administering a noxious substance. And for attempted murder, life in prison. Her bail hearing has been rescheduled for tuesday. But something interesting. The judicial system in canada is a little different from here in the states. She has a choice of choosing a judge or a jury to hear her case now. Interesting which one she'll decide could be on tuesday. We'll keep an eye on it. John, thank you.
