The Los Angeles County district attorney's office says a sheriff's deputy has pleaded no contest to charges that he smuggled drugs into a courthouse jail by concealing them in a burrito.

A Justice System Integrity Division prosecutor says 27-year-old Henry Marin entered the pleas Monday in Superior Court to one count each of bringing drugs into a jail and conspiracy to commit a crime.

An indictment alleged that in early 2010 Marin conspired with one or more persons to transport drugs into the county's airport-area courthouse, where he was assigned to work.

Marin has been relieved of duty. He'll be sentenced on June 25 after prosecution and defense arguments over the appropriate punishment.
