Ghost guns — what many call unserialized firearms made out of unfinished gun parts — is raising big concerns about safety, according to a report by ABC Action News.
Last July on the streets of Baltimore, Dayten Harper shoots at police officers with an AR rifle. Officers fired back and killed Harper.
In California three years earlier John Zawahri uses an assault rifle on a shooting spree. Police say he killed his father and brother at home then fired dozens of shots at and around Santa Monica College killing three.
What do both of these guns have in common? They had no serial numbers, no scratches, they were home made and are untraceable.
