Digital Evidence

The Digital Evidence Unit receives requests to analyze evidence that is submitted in three areas: forensic computer, video, and audio analysis.
 

The North Carolina State Crime Laboratory was the first agency in the world to become ASCLD-LAB accredited in digital evidence in December 2003. The Crime Lab is an important resource for laboratories nationwide that are interested in obtaining accreditation in the digital evidence discipline.

 

Computer Analysis
Computers seized at crime scenes may contain vital evidence. Forensic computer analysis provides law enforcement and criminal justice agencies the recovery and analysis of computer digital evidence, especially in crimes involving children.
 
Crimes against children such as sexual exploitation of a child, indecent liberties, statutory rape, and child pornography, account for the majority of computer submissions.
 
Other computer cases involve homicides, conspiracy to commit murder, financial crimes, fraud, and identity theft.
 
Video Analysis
Video tapes often document the commission of a crime and provide the only leads to the investigator. The Crime Lab receives requests throughout the state to analyze video evidence, especially video surveillance tapes.
 
The AVID Video System can digitize entire sections of video tape and provide investigators with computer enhanced photographs, as well as motion videos that isolate the suspect during the commission of a crime.
 
Audio Analysis
When criminals leave behind audio evidence about a crime, local law enforcement can request forensic audio analysis to enhance and preserve the evidence.
 
Often audio recordings are muffled or unclear and must be enhanced using state-of-the-art computer digital enhancement techniques in order to be understood.
 
Graphics Unit
The Graphics Unit provides support to all law enforcement agencies, other state agencies, and District Attorneys throughout North Carolina.
 
Graphics services include crime scene reconstruction sketches, court exhibits, diagrams, charts, displays, name tags, brochures, pamphlets, books, law enforcement bulletins, creation of logos, certificates, organizational charts, diplomas, and special projects.
 
The unit uses specialized crime scene reconstruction software. The unit has provided court exhibits for several high profile cases such as the homicide of Kathleen Peterson in Durham which involved approximately 141 exhibits produced by the Crime Lab for the prosecution.
