Former Marine Christian Ferrari, 23, was sentenced to 37 months in federal prison for selling 22 unregistered 'ghost' rifles to undercover ATF agents. Ferrari conducted the sales in San Diego and El Cajon over a two-month period, earning nearly $24,000. The rifles, many with unlawfully short barrels, were sold under the pretense they might be bound for Mexico. U.S. District Judge Cynthia Bashant emphasized the significant danger Ferrari's actions posed, noting his military background should have made him more aware of the risks. Ferrari expressed remorse, attributing his actions to untreated ADHD. His defense argued for leniency, highlighting his remorse and support from family and fellow Marines.
