Carroll D. Buracker, a man considered by many as a leading candidate to become the next chief of the Fairfax County Police Department, was named yesterday deputy chief of the 672-member force.

Buracker, 36, a 14-year veteran of the Fairfax department, will replace Kenneth R. Wilson, who retired March 23 to seek the Democratic nomination for county sheriff.

County officials say they consider Buracker, who has supervised every division on the force, as a top candidate to succeed Richard A. King, 48, if King should decide to retire. King has not announced any plans to leave the force, although he has served long enough to qualify for retirement.

Buracker, who joined the force as a patrolman, holds bachelor's and master's degrees from American University. He will be paid $34,000 as deputy chief.

King also promoted Harry Sommers, who had served as commander of the Groveton District station, to commander of field operations for the Groveton, Franconia and West Spring-field districts. Sommers, 41, replaces Maj. Richard Lester, who is retiring after 28 years on the force.

Al Barbee, 36, former commander of the Franconia District station, has been named to replace Buracker as the head of the department's services bureau, which includes about 400 civilian employes.
