A South Carolina woman has been sentenced to 25 years in prison for killing her husband by poisoning his water with eye drops. As Lana Clayton's husband, Steven, lay dying at their mansion in July 2018, she took his phone away so he couldn't call for help, South Carolina Circuit Court Judge Paul Burch said during sentencing. Clayton pleaded guilty to manslaughter in connection with the killing her husband and claimed he was abusive. The Visine plot was not the first time prosecutors say the wife tried to do away with her husband.
