Here's an interesting story: Nearly a year ago a couple, traveling from St. Lucia to London, befriend a fellow traveler who explains that he is over the liquor limit and requests that the couple take one of his bottles of RUM. "No problem", they say as they depart the plane and get into a taxi driven by another friend.
On their way home, in lieu of payment for the taxi ride, they offer the driver their newly found bottle of RUM; he accepts. The very, next day the taxi driver tragically dies of a heart attack.
Nearly a year after the cab driver's death, his nephew and his nephew's friend discover the bottle of RUM and decide to toast the dead man. Immediately after drinking their dedicated shot the two men fall over in near death. They are rushed to the hospital where they nearly die from cocaine poisoning. As it turns out, the bottle of "RUM" turned out to be LIQUID COCAINE.
After testing, it is discovered that the bottle contains almost 9oz. of cocaine dissolved into the RUM. Prosecutors quickly realize that the cab driver's death a year ago was also caused by drinking the "RUM". There is no way to prove that anyone knew of the cocaine or whom is responsible for it being dissolved into the RUM.
