The final man involved in a decade-long drug investigation pleaded guilty today to a cocaine charge. Kevin Forrest of Abbeville is believed to be a part of a group that, since 1990, had been operating out of Texas, distributing cocaine-turned into crack throughout Abbeville. Investigators learned that a police officer, pharmacist, and a number of Abbeville residents were involved. After original charges against Forrest were dropped in 2005, authorities say he returned to drug trafficking the following year. In 2007, Forrest was brought in again for dealing cocaine. Today's plea was to possession with intent to distribute. Forrest faces up to 20 years in prison, a $2 million fine, and a mandatory 4 to 5 years of supervised release after he gets out.
