Before reporting: a practical Guide on what to do and how to file a criminal complaint properly
What witnessed an alleged criminal act or were you a victim?
In the reality of any society is inherent in the crime, and it is no stranger to the colombian society, how do citizens know how to act and what to do in this circumstance?

What is the criminal complaint?
It is the formal act whereby a person informs the authority that a crime has been committed. The Code of Criminal Procedure (CPP) provides that “every person must report to the authority the crimes whose commission has knowledge” (art. 67), and anyone can present it, not just the victim.
However, it doesn't always work the same way: there are exceptions and important differences. For example, no one is obligated to report against yourself, against your spouse, partner or close relatives (art. 68 CPP), or when there is secrecy.
In addition, there are crimes that are not investigated ex officio, but only at the request of the victim, the so —called crimes of private action or querellables: in these cases, the investigation and the trial are generally initiated only if the victim files a complaint, and if removed may prevent the continuation of the process. In contrast, the majority of the crimes of public action itself can be investigated from the complaint filed by any person, and the process can continue, even if the victim changes his mind.
Outside of these cases, not reporting a crime, when you have the duty to do so is punishable by law. The Penal Code punishes failure to report crimes the most serious; anyone who fails to inform without just cause for crimes such as genocide, murder or drug trafficking incurs in prison. There is also a penalty for individuals and for public servants who know about crimes against children and do not inform (CP art. 219B).
File a criminal complaint is the first step for the State to investigate and punish the commission of a crime. The complaint is the medium most commonly used to express the knowledge of a crime to the Prosecutor's office, detailing the time, mode and place of the alleged offense.
The report triggered a constitutional duty of the State to investigate and prosecute criminally the fact (CPP art. 66). That is why it is crucial to draft a complete and accurate: a complaint well-formulated facilitates the research, while a false complaint entails criminal liability.
How do you file a criminal complaint?
The complaint may be made orally or in writing, and even by technological means (art. 69 CPP) whenever possible to identify a whistleblower. You must include precise data: name of the complainant (identification), date and time of presentation, and a detailed account of the facts (what happened, when, and where), that have knowledge. It is advisable to accompany any available evidence (documents, photos, records, data of witnesses, etc) to support the story.
For example, you can zoom in to a Prosecutor's office or Police department, call lines-of-care (122, available 24/7) or using the virtual platform “Denunciation Easy” on the website of the Prosecutor's office. Beyond the exception of the anonymous complaint, in any case, the complainant should be appropriately identified (identity card or document), and sign the writing; if you do not know how to sign, stamp your fingerprint.
The staff member who receives the complaint will be processed immediately, record the information in the system (generating the NUNC) and refer the case to the appropriate tax.

Where to submit it?
Preferably before the office of the Attorney General (office of the guard or local prosecutor's offices) or with any station of the National Police receive complaints.
All police station and CAI has the obligation of receiving the complaint and refer it to the Prosecutor's office. The office of the Prosecutor and the Police work 24 hours a day, throughout the year, precisely to ensure the receipt of complaints at any time.
In addition, the Office provides online channels to denounce without the need to scroll.
What should you say in the report say?
The drafting of the complaint should clearly explain what happened, how it happened and who were involved (if known). Reporting on the events in chronological order and points to dates and specific places; it avoids speculation and should be precise. Attach all the evidence and / or evidence that you have —contracts, receipts, photos, videos, messages, bank statements, medical reports, expert technicians, and the names and phone numbers of witnesses— because that makes it easier to the Prosecutor's office to check what happened, and guide the research.
This is why it is be very useful to have the representation of a lawyer of the victims that help you to organize information, identify relevant evidence and drafting the complaint; a good accompaniment improves the quality of the complaint, and, in consequence, the guide will continue the investigation.
After the filing of the complaint
If the person filing the complaint is not the victim, they generally do not become part of the criminal proceeding and do not automatically have the right to receive notifications about the progress of the investigation.
In contrast, when the person reporting is the victim, you do have the procedural rights: you must report on the progress of the process, can provide evidence and testify as a witness, and have the right to request protection measures.
In addition, the victim can have a lawyer to receive notifications, follow-up and ensure the protection of their rights during the investigation.

Frequently asked questions
The complaint may be filed by the victim or any other person who becomes aware of the fact, and does not require formalities complex, it is enough to communicate clearly what happened. A demonstration (verbal, written, technical) with the competent authority that describe the punishable acts known, under oath. In summary, it's about giving news criminal to enable the research.
In the procedural field, the lack of complaint from a witness not a punishable offence. However, to make a false report (invent crimes or attributed to someone of a crime, knowing that didn't happen), is in itself a crime. The Criminal Code qualifies as slander or false testimony in such behaviour (arts. 220-221, 442 and concordant).
It is not a mandatory requirement to have a lawyer to file a criminal complaint, any person can go directly to the Prosecutor's office or a Police station and file a complaint. However, having legal counsel can bring important advantages: it helps to write the report with clarity, identify the articles applicable legal, and ensure that you include the essential elements and relevant evidence. In addition, when the case moves towards stages of a formal complaint or hearing, a lawyer (individual or ex officio) may accompany the complainant of their rights and responsibilities.
Not all crimes may be reported freely by any person. In some cases, the law requires that the victim (or his legal representative) who present a complaint to the start of the criminal action. These are the so-called crimes querellables or private action. In other words, if the fact is of this type, the Prosecution can not start an investigation just with a complaint filed by a third party: there must be the express will of the victim to move the process forward.
The Code of Criminal Procedure (art. 74) points out which are these offences. In general, these behaviors are considered to be less serious, or that primarily affect private interests, such as minor personal injury without sequelae, the defamation and slander, theft simple low amount, the scam of low amount, or certain cases of false documentary mild, among others. In these crimes, the complaint works as a kind of authorization that the victim grants for the State to investigate.
It is important to bear in mind that the complaint must be filed within six months of the commission of the fact (art. 73 CPP). If the victim does not do so within that period, the right to initiate criminal action expires, that is to say, you will lose the opportunity to open an investigation.
In contrast, the crimes are not querellables, also known as public action, may be reported at any time (while not prescribed by the criminal action), and the Prosecutor's office may investigate them even if the victim does not request or you change your mind later.
In summary, while the complaint may be filed by any person who has knowledge of a crime of public action, the lawsuit is a step that can only give the victim in the crime of action private or semi-private. That's why, before going on to denounce, it is advisable to seek advice to know if the fact is querellable, since it depends on that the research may or may not start.
And the special request, which is the pathway to initiate criminal proceedings for offences committed abroad under certain conditions (CPP art. 75). The process the Attorney General at the request of the authorities or the victims.
In general, there is not a fixed term only to file a criminal complaint to the Prosecutor's office, as many crimes are public action and the law does not impose a term for explicit, to denounce them. However, you can play against factors such as the prescription of the criminal action or not there is sufficient evidence with the passage of time.
The colombian Criminal Code provides that the offenses for which the penalty is not to deprivation of liberty prescribed in five years. In other cases, the limitation periods depend on the seriousness of the offence, the maximum penalty specified, or if the crime is ongoing or continuous.
In addition, for crimes querellables there is a limitation period: the complaint must be filed within six (6) months following the commission of the criminal act.
For the public crimes, there is not a fixed-term “expiration” to report (yes, there is the limitation of criminal prosecution general provided for in the Penal Code); however, the more time that passes, the more difficult it will be to gather evidence. Therefore, it is advisable to report as soon as possible. In any case, the complaint late does not result in a criminal penalty by itself, but may cause the Prosecution to file the case because of lack of progress or prescription of the action.
Once filed the complaint, you can't just “check out” because the criminal action is public. The prosecutor has the obligation to investigate in spite of the will of the complainant.
Only in the crimes querellables (private action) the victim who filed complaint may withdraw from the process. The CPP allows it: at any time prior to the end of the preparatory hearing, the complainant may manifest his decision not to continue. If the judge accepts the withdrawal is filed definitely the case against all investigated.
But this is different from the complaint: the complainant in a public process that is not an option.
In principle, you can learn a crime without revealing any personal data (e.g. via the internet or telephone lines). The law, however, warns that “the writings anonymous not provide evidence or data specific” it will just be archived. In practice, the Prosecution need verifiable data to investigate; therefore, if the complainant is not identified and does not provide bare minimum of evidence, the case will not move. It is recommended to at least give some form of contact or witnesses to the authority to be able to follow the investigation.
To report something knowing that it is a lie is a crime. As mentioned, the false complaint may constitute libel (CP art. 447 CP or art. 221 CP in the case of a false accusation) or even false testimony (art. 442 CP) if it is declared under oath. In any case, those who invent a crime or accused unjustly of another face penalties of fine or imprisonment according to the case.
In addition, the act of warning in a police station, makes it clear that it provides for criminal punishment for those who report falsely.
If the office of the Prosecutor reviews the case and check that there is not enough evidence (or evidence of the facts), it will ask for the file of the investigation. This means that the case is suspended indeterminadamente. The victim will be notified and the criminal prosecution will not proceed.
However, the file is not a judgment against the complainant, it simply reflects that failed to prove the offence. If later there are new elements, the Prosecution may re-open the investigation before the crime may prescribe. If it is finally precluye definitely, there will be no criminal penalty.
Report a crime is a right and a duty of the citizen. To make it clear, complete, and honest is essential for justice to be able to act. Before you report, learn about your rights and responsibilities, know what information you should provide, and what are the legal implications.
Acting responsibly, but without fear: evidence truthful, and collaborate with the research. Remember that you do not denounce you can also have legal consequences (art. 67 CPP, art. 219B, and 441 CP).
Finally, present your complaint to the competent authority and maintain documentation (copies, tests, NUNC) in case it is required. The office of the Prosecutor is obliged to receive the entire complaint well-founded and to investigate it. With accurate and timely information, you will be contributing to the fight against crime and the protection of the rights of the victims.
