Capitol Hill has a new chief of police.

After a three-month, nationwide search and a selection process that considered inside and outside candidates, the former head of the Frederick, Md., police force was officially installed in the post on Monday.

Kim Dine was sworn in by the Capitol Police Board, according to a department release sent out Monday evening. The board, comprised of House Sergeant at Arms Paul Irving, Senate Sergeant at Arms Terrance Gainer and Architect of the Capitol Stephen Ayers, was tasked with leading the search and tapping Dine for the job.

Gainer’s participation in the swearing-in echoed his own previous roles: He is a former Capitol Police chief who at one time worked in the D.C. Metropolitan Police Department with Dine, who spent decades there establishing his law enforcement career.

Dine succeeds Phillip Morse, who retired in May, and more immediately Assistant Chief Tom Reynolds, who had been leading the department in an acting capacity since that time.
