As a Senior Investigator in the DeKalb County District Attorney's Office assigned to the Sexual Assault Kit Initiative Unit (SAKI), Crispin Henry examines cold case CODIS hits to determine if they were previously prosecuted or remain open. If open, he conducts further investigation. This includes interviewing victims, witnesses, and suspects and working closely with the SAKI advocate to contact any surviving victims and notify or update them about their case. The DeKalb prosecutor works with Investigator Henry to decide if there is enough evidence to move the case forward for prosecution.

 Investigator Henry served in the United States Marine Corps from 1985 through 1992 and entered law enforcement in 1993. Before joining the DeKalb County District Attorney's Office, Henry served with the Duluth Police Department, the Georgia Secretary of State's Office, and the Fulton County District Attorney's Office. In the Fulton D.A.'s Office, Investigator Henry worked in the Special Victim's Unit and later the Homicide Unit, where he became the Director of Homicide investigations. In 2009, Investigator Henry joined the DeKalb D.A.'s Office, where he worked in the Public Corruption Unit and the Special Victims Unit before assignment to the SAKI Unit.

 Investigator Henry is widely respected for his commitment to supporting victims of crime and was recognized in 2023 by the Georgia Prosecuting Attorneys Council as the Georgia Investigator of the Year. He has been with the SAKI Unit since its inception and played a vital role in developing a victim contact protocol that places victims' needs first. Henry says, "So many of the victims we serve have endured decades where they were marginalized and not believed. I value the opportunity to support them, believe in them, and help them regain their voice.
