LaShawn Hill, a former aide at the Harbor Pilot Middle School pleaded guilty today to charges he had inappropriate sexual contact with a student there and with another boy at a school in Roxbury.

Prosecutors asked for three to five years on the charges of indecent assault and battery on a child, lewd and lascivious conduct, and lascivious acts with a child. Suffolk Superior Court Judge Carol Ball gave him the lighter sentence, but agreed with a request from prosecutors to require him to undergo treatment, stay away from anybody under 18 without supervision and not apply for any jobs that involve contact with children.

On his release, he will also have to register as a sex offender.

The Suffolk County District Attorney's office provided this account:

"In the first incident in March 2011, Hill inappropriately touched a developmentally disabled boy age 6 or 7 inside a bathroom at the Martin Luther King Jr. School. The boy later disclosed the incident to his older brother and then to his mother.

"In December of that year, a special needs teacher found Hill with a severely autistic, non-verbal, 14-year-old boy in a therapeutic recreation room at the Harbor Pilot School. Both Hill's and the boy’s pants were unbuckled. It was after this incident that Boston Police and Suffolk prosecutors learned of Hill's earlier conduct with the younger boy."

Hill still faces separate larceny charges for allegedly stealing computers from the Harbor School.
