§ 343.2. Rules of evidence; corroboration of accomplice testimony. 1.
A respondent may not be found to be delinquent upon the testimony of an
accomplice unsupported by corroborative evidence tending to connect the
respondent with the commission of the crime or crimes charged in the
petition.

2. An "accomplice" means a witness in a juvenile delinquency
proceeding who, according to evidence adduced in such proceeding, may
reasonably be considered to have participated in:

(a) the crime charged; or

(b) a crime based on the same or some of the same facts or conduct
which constitutes the crime charged in the petition.

3. A witness who is an accomplice as defined in subdivision two is no
less such because a proceeding, conviction or finding of delinquency
against him would be barred or precluded by some defense or exemption
such as infancy, immunity or previous prosecution amounting to a
collateral impediment to such proceeding, conviction or finding, not
affecting the conclusion that such witness engaged in the conduct
constituting the crime with the mental state required for the commission
thereof.
