Criminal mischief is generally the damage, destruction, defacing, or alteration of tangible property (vandalism), done with criminal intent (intentionally or knowingly). Criminal mischief charges often arise from (1) damage to a home or dwelling; (2) damage to a place of business; (3) damage to a motor vehicle; (4) damage to a school; (5) defacement or destruction of public or private property (graffiti, etc.); or (6) tampering with public water, gas, power, or communications.

Criminal mischief laws are generally located in a state’s statutes—usually in the penal or criminal code.

In Connecticut, criminal mischief is addressed under the Connecticut General Statutes, specifically within the penal code. The statutes categorize criminal mischief into different degrees based on the severity of the damage and the circumstances of the offense. For example, First Degree Criminal Mischief (CGS § 53a-115) involves damage to property by means such as explosives or by intentionally tampering with a public utility, which can be a class D felony. Second Degree Criminal Mischief (CGS § 53a-116) includes acts like tampering with property to endanger a person or property, and can be a class A misdemeanor. Third Degree Criminal Mischief (CGS § 53a-117) and Fourth Degree Criminal Mischief (CGS § 53a-117a) cover other forms of property damage, including graffiti, and can range from a class B misdemeanor to a class C misdemeanor. The intent behind the act, such as knowingly or intentionally causing the damage, is a key factor in these charges. Penalties can include fines, imprisonment, and restitution for damages caused.
