Thirty-four agents are graduating from the Oklahoma State Bureau of Investigation Advanced Investigative Academy.
The agents graduated Tuesday from the academy.
Agents hired since 2007 attended the six-week academy to learn advanced skills in areas such as blood stain pattern analysis, investigative interviewing and advanced interrogation techniques and crime scene investigations.
The Bureau planned an academy a few years ago, but budget constraints would not allow for it.
The agents are assigned to regions across the state. Six officers from police departments and sheriff's offices are also graduating from the academy.
