Riley says he is positive the object Darius Cain threw in the river was a handgun, and that he's pretty sure it was a 9mm. However Riley was a good 20 feet from Cain when he threw the gun, and it was only visible for a split second before Cain threw it. There is no way that Riley could tell what caliber the gun was under those circumstances, the best he could do with certainty is identify it as a revolver or a semi-automatic, and someone familiar with guns would be able to likely tell the make (Beretta, a Colt 1911 variant, Glock, SIG Sauer, etc) but that's about it. A person familiar with guns would also know the only way to tell what caliber a handgun is would be by getting a close look at the engraving on the slide that lists the caliber. All of the mentioned manufacturers make handgun models chambered in various calibers that from a distance would all look the same to the naked eye. For example the victim's rival owned a SIG Sauer 9mm, the most common SIG Sauer models are the P220, P226, P228 & P229, which come in a variety of calibers: .22 LR, .380 ACP, 7.65x21mm Parabellum, 9x19mm Parabellum, 9x21mm IMI, .357 SIG, .40 S&W, .45 ACP & 10mm Auto. From 20 feet a person cannot visually determine which of those calibers one of those models is chambered in, the same goes for any other model of gun.
The murder victim is a WNBA star who gets shot at Madison Square Garden shortly after a "very important game" in which she hit the winning shot. Her killing happens sometime in January, yet the WNBA season goes from May to September, so there would be no WNBA games of any kind being played in January.
During the trial, Darius Cain's attorney makes the claim that his aggravated assault and attempted murder convictions happened during a prison fight while incarcerated for marijuana possession. He claims that Cain was just defending himself when another inmate attacked him. However aggravated assault is only charged when a person assaults and seriously injures a police officer or peace officer, or a minor under the age of 11, it would not be charged for assaulting a fellow inmate. Which means EADA Price missed an opportunity to impeach his credibility, if he was convicted of aggravated assault he attacked and seriously injured one of the corrections officers, not a fellow inmate, and there certainly wouldn't have been any 11 year old inmates, ergo he just committed perjury.
Detective Yee said that Nia Moore has a 9mm SIG Sauer registered to her, and that she bought it three months ago. When Detectives Riley and Shaw interview Moore she said that she bought it for protection, but mentions she's never fired it. For one thing it is reckless and irresponsible to own and carry a gun for protection if you've never fired it, it is critical to become familiar with properly using and firing a gun in order to effectively use it in a life and death situation. Which is why New York requires that anyone applying for a New York State Pistol Permit must first complete a 16-hour firearm safety course, which also includes a 2-hour live-fire training session where a person must demonstrate a basic knowledge of how to properly & safely load and fire a gun, they have to fire at least 20 rounds from the same gun they are registering to purchase. And if a person is applying for a carry permit they must perform a live fire demonstration with the gun they are registering to carry. So her claims of not firing it are inaccurate.
