He has the right to remain silent. Only idiots talk to investigators/cops. Remember, no matter what he says it will be twisted around and used against him later. Petty theft is a crime of moral turpitude, and if convicted it will really hurt his school/employment aspirations. He should talk to a lawyer, who may be able to work out a deal with the Judge whereby he can earn himself a dismissal down the road.
