Caren Campano mysteriously disappeared from her Oklahoma City home after having a fight with her husband. Upon encounter with the detectives, Caren’ s husband allowed them to look around the house and this inevitably proved to be his huge mistake. The detectives found a huge stain on the master bedroom’ s carpet which appeared to be a bloodstain. The forensic department performed numerous tests on the sample which are listed below: Microcrystal Hema Stick test: The blood testing kit utilizes a blood sensitive chemical to identify human blood in samples collected from the crime scene.
The Hema stick test was performed on the sample collected from the bedroom carpet of Caren’ s house. The test came out to be positive because the sample indeed contained human blood. Luminol: The chemical luminol is a crystalline solid which produces chemiluminescence upon contact with blood. The Luminol spray is used to identify bloodstains which are not visible through the naked eye. Luminol is one of the most popular blood identifying techniques that forensic investigators use to detect traces of blood at a crime scene. The crime scene is evenly sprayed with luminal and traces of blood are identified by the eerie blue illumination produced by the chemical in darkness.
Apart from the brownish stain on the bedroom carpet, Caren’ s house was relatively spotless. However, the luminal test revealed that the house was literally covered with blood. The forensic investigators were left in no doubt of the fact that a virtual bloodbath had taken place because numerous places around the house illuminated. Blood analysis techniques such as the ones performed in Caren’ s case provided valuable information which simplified the case.
Detailed information is interpreted from the pattern of bloodstains formed at the crime scene. The pattern formed helps determine the track of blood and the number of blows inflicted. Moreover, the pattern also provides information about the location and position of the weapon used by the killer to inflict the wounds.
