Assault in Minnesota covers a range of offenses, from causing minor injuries to inflicting life-threatening harm. The state categorizes assault into degrees, with first-degree being the most serious.
Knowing the differences between these degrees is crucial because the penalties, and your defense options, vary significantly. At Martine Law, our Minnesota assault lawyers defend clients facing all levels of assault charges.
First-degree assault in Minnesota
Minnesota Statute § 609.221 defines first-degree assault as:
- Causing great bodily harm to another person, or
- Using deadly force against a police officer, judge, prosecutor, or correctional employee
Penalties:
- Up to 20 years in prison
- Fines up to $30,000
First-degree assault is always charged as a felony. “Great bodily harm” means injury that creates a high probability of death, causes serious permanent disfigurement, or causes permanent loss or impairment of a body part.
Second-degree assault in Minnesota
Minnesota Statute § 609.222 covers second-degree assault, which involves:
- Using a dangerous weapon during the assault, regardless of the level of injury
- Causing substantial bodily harm with a dangerous weapon
Penalties:
- Up to 7 years in prison and $14,000 in fines, or
- Up to 10 years in prison and $20,000 in fines if substantial bodily harm is caused
A “dangerous weapon” can be anything from a firearm or knife to an object used in a way that could cause serious injury.
Third-degree assault in Minnesota
Minnesota Statute § 609.223 defines third-degree assault as:
- Inflicting substantial bodily harm, or
- Assaulting a minor in a pattern of child abuse, or
- Assaulting a child under 4 years old and causing certain injuries
Penalties:
- Up to 5 years in prison
- Fines up to $10,000
“Substantial bodily harm” refers to temporary but significant disfigurement, loss of function, or injury causing substantial pain.
