How often do family members get involved in crimes together, and what kind of legal precedent does this case set?

According to law enforcement expert Will Spilar, direct family involvement in crimes as seen in this case is unusual. Typically, family members help after the fact by hiding suspects or covering up crimes, rather than actively participating in the crime itself. This mother-son case is distinct because the mother was directly involved, actively assisting her son during the commission of the crime. Legally, this case follows the felony murder rule principle, where all participants in a crime are held responsible for any deaths that occur during its commission. When individuals act 'in concert' as the mother and son did, they share legal culpability for the murder, regardless of who fired the fatal shot. This collaborative criminal action was proven in court, leading to their convictions.
