When Cerreta and Logan enter the crime scene, Cerreta holds a cloth over his mouth and nose. As they are talking to the arson investigator on the stairs, the camera angle switches and Cerreta is no longer holding the cloth.
Branch says that Guerra should be charged with, among others, criminal solicitation in the first degree. Criminal solicitation in the first degree is when a person over the age of 18 solicits, commands, requires or forces a minor under the age of 16 to engage in conduct that would constitute a class A felony. Since both Collins and Guerra are adults then Guerra would be charged with criminal solicitation in the second degree. CS in the first degree is a class C felony, second degree is a class D felony. Since Branch is the District Attorney he should know the difference.
Collins should be charged with 53 counts of murder in the first degree, not murder in the second degree. In most states premeditated murder is charged as first degree murder, however in New York it is usually charged as aggravated murder in the second degree. In New York the charge of murder in the first degree is reserved for very specific types of murder, the most common being the murder of a police officer. If a murder is committed during the commission of, or in furtherance of certain crimes, like arson in the first degree, then it becomes murder in the first degree.
