Someone was accused of rape but found not guilty of first degree sexual assault but guilty of second degree sexual assault
Not likely. There is no sexual assault statute. He could have been found guilty of Sexual Abuse, aggravated sexual abuse, Sexual act or course of sexual conduct against a child all in the second degree.
Sentencing for these crimes range from probation to many years in Prison, depending on the crime charged.
Generally there is no "standard" sentence for any crime in NY. There are mandatory minimums and there are maximums but no standard. With that said, Sentencing often depends on a myriad of things including the relationship between the actor and the victim, the age of each and the age difference. The acts and the issue of "consent". The background of the individual who is accused and the recommendation of the victim and the probation officer as well as any expert the defense offers on these issues.
