A shortage of investigative and security expertise is catching the eye of former government officials ready to move into the private sector. Add to the growing list Christopher Ryan, a former prosecutor at the Manhattan District Attorney's Office.

Ryan, who was assistant DA before becoming chief of violent criminal enterprises at the Manhattan DA Office, will join investigative firm K2 Intelligence as a managing director in its strategic risk and security practice after more than two decades serving as a public prosecutor.

Legaltech News caught up with Ryan to discuss his work as a prosecutor, including how he pioneered the use of social media evidence in gun-related cases, and how he intends to continue the work he did at the Manhattan DA while in the private sector.
