Rexxfield has just received news from a joint task force of US Marshals and the Maryland State Police Force of confirmation of arrest of a murder suspect. They were looking for a fugitive from justice, Dinkue Brown, 27, who has been on the run, in connection with the murder of 26 year old Luis R. Rodriguez, since June 21, 2013.
Maryland State Police called Rexxfield on August 14, seeking advice on obtaining information from Google. Rexxfield’s CEO Michael Roberts, offered Rexxfield’s technical and investigative assistance far beyond that scope.
The Rexxfield team developed a pretext for a sting operation and then, after approval from law enforcement, conveyed a message to one of the suspect’s family members. The message had one of Rexxfield’s proprietary forensic tripwire payloads attached thereto.
Subsequently, the tripwire transmitted numerous electronic footprints, including incidents triggered by the fugitive, from behind anonymous proxy servers in an attempt to disguise his location. Over the next few hours Rexxfield continued to work with the task force to circumvent the fugitive’s attempts to obfuscate his activities and location.
As a result of the digital artifacts and intelligence collected by Rexxfield, within a few hours the team identified a cell phone number. It was allocated to a disposable SIM card in the possession of the fugitive, but it did not reconnect to the cell-tower network after Rexxfield first discovered it — ergo triangulation was impossible. It appears that the fugitive purchased the SIM card to use once for an emergency and thereafter destroy it.
After obtaining a court warrant, U.S. Marshals were able to obtain the unique device identifier [UDID] that was associated with the one-time-use SIM card. A few days later the same UDID popped up again in association with a new disposable SIM card. The Marshals were then able to triangulate the fugitive who was in possession of that cell phone.
The fugitive was found at the triangulated location in Indiana, was arrested, and is now in police custody. Brown waived his right to fight extradition and is being held in the Wayne County Jail without bail. The Worcester District Attorney’s office is making arrangements to transport Brown for his arraignment in Fitchburg District Court.
