Petroleum County Jail Booking Roster
After being arrested and taken into custody, and after being read their Miranda Rights, an offender will next be transported to the local police or department or the Sheriff’s Department in Petroleum County for booking.
Booking is very involved and requires multiple steps in the process, however, keep in mind that most attorneys will advise that an offender remain silent and not offer any additional information about the crime they have been arrested for because anything they do say may be recorded and may very well be used against them in court.
Booking includes having their photo (mugshot) and fingerprints taken, as well as being asked a lot of questions about their personal history and state of mind. If it’s a serious felony, their DNA may also be taken. They will also be checked for warrants in Petroleum County and other Montana and USA jurisdictions.
If the offender was arrested for a DUI offense, and has refused a breathalyzer test, they may also be forced to have blood drawn by a doctor or nurse.
It is also very likely that the offender will undergo a humiliating full body search while in the nude. This includes bending over, spreading their cheeks in the direction of an officer, and coughing. They will also be walked through a metal detector or x-ray machine, like those used at an airport.
The arresting jurisdiction will ask about gang affiliations, tattoos, medical conditions, prescribed medication they are taking, recreational drugs they are on or addicted to, allergies, if they are suicidal, and other relevant information that will help with determining their cell assignment and special needs.
During the arrest and booking process an offender will also have all their personal property confiscated and held for either their release from jail, or with the offender’s approval, released to a friend or family member.
Personal property includes the clothing they are wearing, money, wallets, purses, cell phones, jewelry, body rings, earrings, watches, and even glasses if they are deemed a security risk. If they are allowed to keep their shoes or sneakers, the laces are removed.
At this point the offender will be allowed to make a free phone call to a person of their choice to notify them of their arrest, and/or arrange a bond or bail for their release.
If the offender is being detained and housed while awaiting arraignment, the Petroleum County Jail will provide a jail garment and slip-on shoes, a blanket, sheets, soap, toothbrush, toothpaste, and a towel.
Often, before they are dressed in the jail outfit and brought to their housing location, they will be forced to take a shower and undergo a disinfectant treatment for body and hair lice, scabies or other pests that may be residing on their person.
Booking can take anywhere from an hour to 24 hours or more. It all depends on the number of people that are awaiting processing, the number of staff on duty at the time, and the behavior of the offender.
If the offender is heavily intoxicated and/or violent, the Booking Officer may decide to stick the offender in a holding cell for several hours until they become more manageable.
Yes, Petroleum County recognizes most types of bonds.
Petroleum County permits five types of bonds:
• By a deposit with the court of an amount equal to the required bail of cash, stocks, bonds, certificates of deposit, or other personal property approved by the court.
• By pledging real estate situated within the state with an unencumbered equity, not exempt, owned by the defendant or sureties at a value double the amount of the required bail.
• By posting a written undertaking executed by the defendant and by two sufficient sureties.
• By posting a commercial surety bond executed by the defendant and by a qualified agent for and on behalf of the surety company.
• By posting an offender's driver's license in lieu of bail if the summons describes a violation of any offense as provided in 61-5-214 and if the offender is the holder of an unexpired driver's license.”
For most non-violent crimes bail is preset according to a bail schedule. More serious and violent crimes require a defendant to appear in front of a judge who will determine bail amount.
For most non-violent crimes bail is preset according to a bail schedule and that information is available during the booking process. More serious crimes will require a hearing in front of a judge. This hearing, also known as a bail hearing, will generally be scheduled for the next court day. State law requires the bail hearing to take place within 48 hrs. not counting weekends or holidays.
