CSI: NY

Goof: When Danny and Lindsay enter the house in Amityville, Danny lays down a series of acrylic step plates presumably to preserve the crime scene. However, when they first arrive at the location, the sheriff walks out of the front door of the house, which indicates that the local law enforcement has already contaminated the crime scene. In a later scene, Lindsay is alone in the main hallway of the house and is attacked by the old woman. There are no step plates in the scene even though the bodies of the murdered family are still laying in the hall.

The blind woman tells Mac that he is cursed and lays out three Tarot cards: the Tower, the Hanged Man and the Devil. The Tower stands for death, chaos, ruin and also revelation of the hidden truth. The Devil stands for lack of faith. The Hanged Man symbolizes sacrifice. Josephine tells Mac that 333, the Devil's son, acts in response to the sins of our youth. Apparently, Mac keeps a secret that is connected to something that happened to him in his youth, some kind of sin from his past that is buried and struggling to come to light.

Guest star Seth Peterson co-starred with Melina Kanakaredes in the series Providence playing brother and sister. But they didn't appear together in this episode.

Goof: (?) Jurisdiction wise, the NYPD shouldn't investigate a case in Amityville in Long Island. Apparently, a plane crash keeps the local investigators busy; however can every investigator in the Suffolk County Police and the state police department be busy? The crime scene needs forensics experts, it is possinble the plane crash, a HUGE scene to cover, does require the forensic teams of all of Suffolk County (which while large, if an entire plane needs to be encompassed it could be possible). Also, Halloween is one of the busiest nights of the year as many hooligans feel the need to vandalize things.

Just after the titles are shown, the camera pans across some buildings where the lighting pattern in the occupied offices makes a skeleton skull.

Tetrodotoxin comes from the Puffer fish.

Goof: Mac's statement that there is no reason to make a voodoo doll other than to wish harm on someone is incorrect. Voodoo is actually focused on healing and protection from evil spirits and there has never been any evidence of a so called 'voodoo doll' being used by followers of the religion. The myth was perpetuated by English merchants in the 18th century and is believed to be based on practices of European witchcraft at the time. The lurid tales of voodoo dolls, curses and zombies however proved popular with the masses and later with Hollywood, and the image of a voodoo priest sticking pins into a 'voodoo doll' stuck.

Goof: During the opening act, Lindsay states that the address of the crime scene is 1135 Ocean Ave. in Amityville. Even though Ocean Ave. is where the actual "Amityville Horror" house is located, the address is wrong. Addresses on that street are only 3 digits and the house was located at 110 Ocean Ave.
