One who knowingly, voluntarily, or intentionally, and with common intent and criminal purpose shared with the principal offender, solicits or encourages another to commit a crime or assists or attempts to assist in its planning and execution. Normally, oneÂ’s mere presence while knowing the crime is about to be committed, without any contribution to the commission of the crime, does not make a person an accomplice. However, in some situations, knowledge combined with the failure to make an attempt to prevent the crime will make one an accomplice. An accomplice is normally regarded as just as culpable as the person who actually commits the crime. See also accessory, aid and abet, and conspiracy.
