Because the amount of physical evidence gathered at a crime scene may be significant, the need to have an individual in charge of ensuring that all evidence is properly packaged and recorded is crucial. Evidence received by an evidence collector may include: photographs; film rolls; body parts and fluids; narcotics; money; weapons; and DNA evidence, among others.

Evidence specialists are an important part of CSI teams, as they are responsible for:

  • Receiving, maintaining, and releasing custody of physical evidence
  • Documenting evidence received and released
  • Preparing evidence for storage
  • Preparing evidence for laboratory testing
  • Submitting and monitoring laboratory submissions and results
  • Determining proper laboratory testing requirements
  • Sealing, labeling and packaging evidence for laboratory use
  • Creating photographs and/or videotapes of evidence
  • Transporting evidence from the crime scene
  • Preparing evidence for courtroom use

Evidence specialists must ensure that all evidence is processed and stored according to strict guidelines and protocols, and they must ensure that all evidence is properly documented and that all documents relating to the evidence are completed and correctly filed. Their work often involves entering information into a computer database.

These CSI professionals also assist the court, investigators, and other law enforcement agencies who want to obtain information or evidence in storage. They ensure that evidence storage areas are properly secured and that all security standards are met so as to eliminate the possibility of evidence contamination. Further, they also ensure that perishable evidence is properly stored at the correct temperatures.

Evidence specialists are responsible for a number of clerical duties related to physical evidence, so they must be highly organized and meticulous about their work. Their job scope includes: receiving, processing, storing, safeguarding, delivering, releasing, and disposing of highly valuable physical evidence. As such, they must maintain a precise inventory of evidence and ensure that all physical evidence is carefully and safely handled at all times so as to maintain its integrity.

Basic clerical duties for this position also include:

  • Educating law enforcement personnel , the courts, and the general public on departmental procedures related to the storage and release of evidence and property

Education and Experience Requirements for Evidence Specialists

Evidence specialists must have excellent written and oral communications; they must have superb organizational skills; and they must have a deep understanding of crime scene investigation, forensic laboratory procedures, and the criminal justice system.

These well-rounded CSI professionals therefore often seek an associate’s or bachelor’s degree in criminal justice or forensic science, supplemented by coursework specific to property and evidence handling, classification, and storage. They must have excellent computer skills and a background in managing a warehouse or storage area or working in a law enforcement setting.

Candidates with bookkeeping and secretarial skills are often preferred candidates for a position as an evidence collector.

Some states have specific requirements for evidence collectors, as well. For example, evidence collectors in Texas must be able to obtain a certificate through the Texas Association of Property and Evidence Inventory Technicians within 12 months of their hire.

Salary Expectations for Evidence Collectors

Recent job postings reveal that the average salary range of evidence collectors is between $35,136 and $48,432.
