Tech experts help solve complex crimes

After finding success using in-house computer technicians to crack financial crimes, Beijing's prosecuting authority is enlisting specialists in multiple fields to aid investigations in complex cases.

A database of experts, including some at third-party institutes, is being created for prosecutors to use when they need help in obtaining and verifying evidence, according to Wang Ta, an attorney for the Beijing People's Procuratorate.

The move comes after the authority launched an informal pilot last year that saw some employees in its IT department switch from fixing broken computers and installing new software to helping probe a criminal suspect's digital activities.
