A man convicted of having sex on a Florida beach in front of families will soon learn how long he must spend in prison.

Jose Caballero is scheduled to be sentenced Monday. He faces a possible 15 years in prison, but prosecutors say they will seek 2.5 years.

He and 21-year-old Elissa Alvarez were convicted in May of two counts of lewd and lascivious behavior. They were videotaped having sex on a Manatee County beach last July in broad daylight. Witnesses testified that a 3-year-old girl saw them.

Alvarez was recently sentenced to time served. Prosecutors say they are being tougher on the 40-year-old Caballero because he previously served eight years for cocaine trafficking.

The case drew international attention because of the couple's brazenness. Both must register as sex offenders.
