Lanie Tamala Jones says the murder weapon was a 9mm "automatic". As a coroner, she would never misidentify a semi-automatic pistol as an "automatic".
At 29:36, a DMV record is shown for Jay Hixton listing his address at 215 W. 86th Ave, New York, NY 20013. There is no West 86th Ave. in New York and the zip code 20013 is in Washington, DC.
When Beckett is investigating the crime scene, she claims that the gun (.357 Magnum) found next to the victim would create a larger entry wound than that on the victim. However the bullet diameter of a .357 Magnum is almost identical to that of the 9mm which is claimed to be the actual murder weapon. These weapons would leave entry wounds of comparable size and could not be distinguished with the naked eye.
