Detailed Guide: Essential Mobile Data for Violent Crime and Homicide Investigations

Get to the bottom of violence with mobile testing

Mobile evidence is essential to solving cases of violent crimes and homicides. But consider the difficulty of tackling a homicide case when key evidence is encrypted and inaccessible. Without access to locked devices, crucial evidence could be permanently hidden behind advanced smartphone encryption, potentially hampering the investigation. It would be a significant setback to inform the principal investigator that no progress can be made unless the device can be unlocked.

That is why researchers needMagnet Graykey. Graykey is the leading solution for accessing locked or encrypted devices that would otherwise be inaccessible without the passcode, including iPhone and Android devices. By overcoming the barriers of encryption, Graykey ensures that investigators can recover and use critical evidence, making it an indispensable tool in modern digital forensic investigations.

And with the combination ofMagnet GraykeyandMagnet Axiom, data from iOS and Android devices can be unlocked, and from there, forensic examiners can extract, process, analyze and report on digital evidence involved in violent crimes and homicides.

Navigating the increasingly complex mobile landscape

In addition to unlocking digital evidence, Graykey extracts credential files such asiOS Keychainand theAndroid Keystore, which can provide possible passwords. These credentials work withMagnet Axiomto decrypt applications with additional layers of encryption. This capability extends to many third-party iOS apps, includingsnapchat, WhatsApp, signal, and even the native notes ofApple Notes.

Getting actionable mobile intelligence

In this example, we will use the scenario of a homicide investigation where the suspect has been identified and there is legal authority to search and analyze his locked iPhone. During the interview, the suspect denies being at the scene of the homicide, refuses to provide the passcode to his encrypted phone, and requests an attorney.

If your agency does not have access tograykey, the options are limited to relying on other agencies with extraction capabilities or placing the phone in the evidence room with little chance of obtaining the data.

Geolocation data: The digital crumbs

However, if your agency usesgraykey, crucial data can be recovered to access the suspect's iPhone and then process the extraction withAxiom. In this scenario, geolocation data was recovered, revealing the device's trajectory toward the crime scene at the time of the homicide. Withoutgraykey, the investigation team may not be aware of the suspect's presence at the scene.

Even if the phone is unlocked and a logical extraction is performed, cached geolocations and other crucial evidence will not be captured. Only a full file system extraction can access this data, including cached geolocations, databases ofKnowledgeC, data fromBiome, third party communications and more.

Without this complete extraction, investigators could miss crucial evidence that the suspect's iPhone recorded, such as his journey to and from the crime scene. This vital information could be the key to solving the case and ensuring justice.

Pulling the thread of digital communications

The importance ofdigital communicationsas evidence in investigations of violent crimes or homicides cannot be overestimated. Thetext messagesThey can offer crucial information about the suspect's motives, relationships, and actions that led to the crime. They can reveal threats, plans or alibis, and help corroborate other evidence, providing a complete picture of the events surrounding the crime.

Without access to these communications, critical evidence could remain undiscovered.

Getting the reason from the messages

In this scenario, examination of communication records reveals that the suspect argued about money with the victim shortly before arriving at the crime scene. These messages suggest a financial motive for the murder, which could have remained unknown withoutgraykey. To further simplify digital research, theMobile ViewofAxiomIt is useful for investigating mobile devices, offering an intuitive interface that simulates the real phone. This allows researchers to interact with the device as if they were using it directly, selecting compatible application icons and quickly reviewing associated artifacts. This functionality simplifies the process of discovering vital evidence.

Delving into internet history

Additionally, closer examination of the suspect's phone reveals a series of search terms made the day before the homicide. These searches suggest the motive went beyond financial gain and was drug related. This finding is consistent with the common connection between money and drugs, indicating a deeper relationship between the suspect's financial discussions with the victim and his potential narcotics-related activities. All of these revelations were made possible by access to encrypted iPhone data.

Closing cases with mobile insights

Not being able to access digital evidence can result in the loss of crucial information that could determine a suspect's guilt or innocence. Key details commonly found in homicide investigations, such as communications, location data, and browsing history, could be lost and significantly impact the investigation. Without the ability to unlock and analyze evidence from smartphones, law enforcement agencies face significant challenges in building strong cases.

As technology advances, so do the challenges faced by law enforcement.graykeyandAxiomThey are indispensable in modern forensic investigations, providing essential access to encrypted data and assisting in solving violent crimes. Their capabilities ensure that the crucial evidence mentioned above is recovered, contributing to justice and closure for affected families.
