A fifth person has pleaded guilty to participating in a 2010 Connecticut warehouse heist that prosecutors say involved up to $100 million in prescription drugs.

Cuban citizen and Miami resident Rafael Lopez pleaded guilty to a federal charge of deliberately hiding his knowledge of a felony, acknowledging he was aware of the heist and helped conceal it.

Prosecutors say Lopez drove one of the thieves to and from Florida.

Prosecutors say five men broke into an Eli Lilly and Co. warehouse in Enfield by scaling a wall and cutting a hole in the roof and stole thousands of boxes of prescription drugs. The theft was believed to be the largest in Connecticut history.

The 50-year-old Lopez faces up to three years in prison when he’s sentenced in February.
