A more thorough explanation:

NONCAPITAL

Noncapital, adjective. Refers to a crime that does not involve or deserve the death penalty.

Example: Noncapital murder.

Noncapital refers to crimes that are not considered serious enough to warrant the death penalty. For example, noncapital murder is a type of murder that does not involve premeditation or aggravating circumstances, such as killing a police officer or committing murder during a robbery. Instead, it is a less severe form of murder that may still result in a lengthy prison sentence, but not the death penalty.
