Mobile phones are often used in criminal enterprises as well as by individual offenders. In criminal cases, almost 80–90% of the cases criminal computer forensic examiners work on are related to child pornography (Nodeland et al. J Crim Justice Educ 30:71–90, 2018). In an effort to fight electronic crime and to collect digital evidence for criminal acts, law enforcement agencies are incorporating the collection of tools for analysis of digital evidence, also known as computer forensics, into their law enforcement infrastructure. Police agencies are challenged with the need to train officers to collect digital evidence and keep up with large and evolving technologies such as computer operating systems and cell phone technologies. Digital evidence is now being used to prosecute all types of crimes. Skilled officers and examiners are needed to examine this critical need in the criminal justice system. This research surveyed 59 (N = 59) Texas police agencies in their use of digital forensic examiners. The findings reflect that numerous agencies often use a part-time police officer/examiner to investigate the digital evidence that comes into the agency that can limit the expertise in the agency. Implications for this research are discussed.

移动电话经常用于犯罪企业以及个人罪犯。在刑事案件中，近 80% 至 90% 的刑事计算机取证审查员处理的案件与儿童色情有关（Nodeland 等人 J Crim Justice Educ 30:71-90, 2018）。为了打击电子犯罪并收集犯罪行为的数字证据，执法机构正在将用于分析数字证据的工具（也称为计算机取证）整合到其执法基础设施中。警察机构面临着培训警官收集数字证据并跟上计算机操作系统和手机技术等大型和不断发展的技术的挑战。数字证据现在被用于起诉所有类型的犯罪。需要熟练的官员和审查员来审查刑事司法系统中的这一关键需求。本研究调查了 59 (N  = 59) 得克萨斯州警察机构使用数字法医检查员。调查结果表明，许多机构经常使用兼职警官/审查员来调查进入该机构的数字证据，这可能会限制该机构的专业知识。讨论了对这项研究的影响。
