There are several factors which affect whether you can obtain official police reports of suicides. Was the report of an attempt or is the person deceased? Is the case currently under investigation? Police reports are generally public record unless they've been sealed or still under an ongoing investigation. When a public record is denied, you will get a reply stating the reason for the request being turned down.
A majority of arrests are at the county or city level, from local law enforcement. Having a case number is helpful. You can find records of arrests using many free sources online, you will need to dig up some of them. Official police reports are different, they are requested from the department which made the arrest. Sometimes requested by defense attorneys for their case. Records of arrest, which means any recorded information in regard to an arrest, can be found in different sources. You can pull up a case from an earlier time and see specifics about the prosecution, filed charges and more. Periodicals have archived reports also and they report on arrests. Without knowing where the arrest happened, specific sources can't be suggested. You can also search previous posts about getting arrest records with a Q and A search below. Type in the keyword arrest, don't be too specific on the search terms, and see how others have obtained their arrest reports/records.
The FL department of corrections has a free public search that shows photos of the prisoners. A name search can be conducted, there are many offenders listed there and worth checking. You can see a list of their offenses going back many years showing arrests/offenses and dates.
If it's a county crime, then the arrest would be by the department that patrols that particular area. If there's an incident report made out the responding department's site will tell you how to request them, you can sometimes get them online.
Address searches show family and spouse's names. If you know any of those, or even a roommate, a thorough address search will show other residents living at that address. Or just do a reverse address search and get resident information. There are many possibilities, depends on how much you already know. If you know where parents, any relatives, spouse, former spouse, roommates and friends reside, you can then run an address search and see residents' last names. Hard to say without knowing all the facts, details, how much is known about the arrest and where did the information about the arrest come from?
Contact the clerk of court in the county where the accident occured and the bf was found guilty
There are a few ways to look up a DUI, specially if you know where to look. If the arrest went to trial, the records department/clerk's office for that court should have the filing. You may even be able to request them online from the court's webpages.
You can either do the check yourself or have the fdle (the Florida Department of Law Enforcement) do it for you by simply requesting it online. Or you can look up court records can see other information such as lawsuits, judgments and more. If the charges are recent, you can check with the police department's website for their inmate/in custody lists. If it is going to trial soon, the criminal court calendar is another free search you can do. Both of these last ones are pre conviction, so it would probably not show up on the fdle's criminal records search.
