The FBI in Nevada has a new special agent in charge.
Aaron Rouse began Monday as the top administrator of the Las Vegas division.
Rouse has 20 years of FBI experience, and served most recently as section chief in the bureau's headquarters counterintelligence division.
He replaces Laura Bucheit, who left in July to become security division assistant director to FBI Director James Comey.
Bucheit spent three years in charge of the Las Vegas office.
The bureau says Rouse has held previous leadership positions at FBI offices in Tampa and San Antonio, and worked in a violent crime unit and joint fugitive task force in the Washington field office.
