According to the Michigan Penal Code Section 750.520(b), a criminal sexual conduct in the first degree will have occurred when an individual has sexually penetrated another and certain scenarios exists. The following circumstances can lead to a charge of criminal sexual conduct in the first degree if the victim is under the age or is at least 13 years old or under the age of 16 and the offender lived in the same home as the victim. If the sexual penetration occurred while the offender was committing another felony such as a robbery, that individual can be charged with the crime of criminal sexual conduct in the first degree. A possible circumstance that could lead to an individual being charged with sexual conduct in the first degree would be if an individual had a weapon or an item that could lead the victim to reasonably believe the item was a weapon while the individual engaged in sexual penetration with the victim.
If one is convicted of criminal sexual conduct in the first degree they will be found guilty of a felony that is punishable according to the following: the offender will be sentenced to life in prison or a term of 25 years if the offender was 17 years old or older and the victim was under the age of 13 or the offender will be sentenced to life in prison without parole if the offender has a prior conviction of a criminal sexual conduct and the victim was under the age of 13.
The classic example of CSC 1 is a male forcing a female to have sex against their will. The male will penetrate the female against their will either with their penis or with vaginal penetration.
Another example of this would be a teacher or family member that has a relationship with the victim and imposing their will.
