An Alta Sierra Man has been arrested for poisoning his girlfriend with Visine. According to Sheriff Keith Royal the victim and her boyfriend had been in a tumultuous relationship when the boyfriend, 27 year old Shayne Curtis Carpenter allegedly placed several drops of the eye medicine into her drink. An ingredient in Visine, Tetrahydrozoline, can cause nausea, vomiting, difficulty breathing, changes in blood pressure and blurred vision. Sheriff Royal says it’s often abused as a date rape drug. 
The woman was treated at Sierra Nevada Memorial Hospital and released. Then she found an incriminating message on Carpenter’s cell phone.
