Will I serve jail time if I’m only 17 and charged with two felony 3's?

This is an extremely serious charge and you must hire an attorney an defend yourself our it will be following you for the rest of your life.

In Michigan anything that is committed by a 17 year old is considered an adult crime, so yes you could serve time.

Your question requires an attorney consultation. It is not a simple question that can be answered on this type of forum. There are many factors that would need to be considered and evaluated. I strongly suggest that you contact an experienced criminal defense attorney for a face-to-face consultation and give him/her all of the facts surrounding your situation. He/she would then be in a better position to analyze your case and advise you of your options.

If convicted of PC 148 BOMB THREAT and you are charged as an adult you will do time. On the felony, the crime is punished by sixteen months, two years, or three years. 148.1. (a) Any person who reports to any peace officer listed in Section 830.1 or 830.2, or subdivision (a) of Section 830.33, employee of a fire department or fire service, district attorney, newspaper, radio station, television station, deputy district attorney, employees of the Department of Justice, employees of an airline, employees of an airport, employees of a railroad or busline, an employee of a telephone company, occupants of a building or a news reporter in the employ of a newspaper or radio or television station, that a bomb or other explosive has been or will be placed or secreted in any public or private place, knowing that the report is false, is guilty of a crime punishable by imprisonment in a county jail not to exceed one year, or pursuant to subdivision (h) of Section 1170.

You have not explained what you are actually charged with so it is impossible to determine if you would score enough to warrant incarceration. The State can file the proper paperwork to have you tried as an adult but that would depend on the charges and your prior criminal history. With the limited information provided it would be impossible to give you a definitive answer. You should consult an attorney.

You either need to hire an attorney in your area or get the public defender appointed to represent you.

That would be probation.

This is fact sensitive and u need to consult with an attorney. As a juvenile you can be incarcerated in a detention center. Prosecutor may ask to try you as an adult.
