How do investigators conclude that someone is a suspect of a crime?

Answer 1

This is a broad question and it would depend on the crime and circumstances.
Generally a suspect is developed by the victims and witnesses that are involved.
Lets say your car window was broken. The police might ask if you know anyone that might do this and you say your ex boyfriend as he threatened you. The police would then consider him a suspect and interview him etc..
In the case of a more serious crime then all the facts are looked at carefully, the ballistics, crime scene evidence, other criminals that reside in the area that have done similar things, family members, ex's, video, and any other credible evidence. Things are then taken step by step to develop evidence to clear or charge the suspect. In addition once the police feel they have enough evidence they then have to go before a State or District Attorney who reviews everything to see if they agree. Hope this helps

Answer 2

Investigators generally conclude that a person is a suspect through, depending on the criminal act, crime scene photo's, forensic evidence, witness and victim interviews. Forensic evidence may include blood, hair, other bodily fluids and fingerprints to name a few.These leads are followed up, which usually identifies the person that may have committed the crime in question. From there the suspect is usually contacted by the investigators and questioned. He/she will be given an opportunity to provide an "alibi" The results of the investigation are then reviewed with the prosecutor assigned to the case, and a decision to charge is then made.
