A mother-daughter duo who used a $4000 drone to drop a package of contraband behind the walls of a Florida prison will themselves serve time as a result of a felony plea deal struck with prosecutors, court records show.

Cassandra Kerr, 40, and Concetta Didiano, 22, this week each entered no contest pleas to introducing contraband into a state correctional institution, a felony carrying a maximum of five years in prison.

As part of a plea deal, Kerr and Didiano (pictured above) are expected to each receive six months in jail when they are sentenced in late-July. The pair will also have to pay court and prosecution costs, according to plea forms.

Kerr and Didiano were arrested in mid-December, shortly after Martin Correctional Institution (MCI) staffers spotted a drone hovering over the facility around 2 AM. Jailers were suspicious that the drone was “possibly delivering a package to the rooftop of one of the inmate housing facilities.”
