MIAMI (AP) — A man described by prosecutors as the leader of an extensive Cuban human smuggling ring has been sentenced to 20 years in prison following his conviction on multiple charges.

The sentence was imposed last week by a South Florida federal judge on 56-year-old Antonio Comin. He was convicted by a jury in March of nearly 100 criminal charges stemming from for-profit schemes to smuggle Cubans into the U.S. using speedboats.
