Embattled Los Angeles County Sheriff Lee Baca will announce his retirement, a law enforcement official said Tuesday.
The official spoke to The Associated Press on condition of anonymity because the official was not authorized to publicly release the information ahead of a 10 a.m. PST press conference planned by Baca.
The 71-year-old sheriff had been running for a fifth term, but the department and jails he headed came under increasing heat in recent months and he was facing his roughest path yet to re-election.
Last month, federal prosecutors indicted 18 current and former sheriff's deputies for crimes including beating inmates and jail visitors, falsifying reports, and trying to obstruct an FBI probe of the nation's largest jail system.
U.S. Attorney Andre Birotte Jr. said the indictments showed that "some members of the Sheriff's Department considered themselves to be above the law" and "demonstrated behavior that had become institutionalized."
Baca has acknowledged mistakes, but also strongly defended his department and distanced himself personally from allegations of misconduct.
"You haven't seen me retire from the job," he said after the indictments were announced Dec. 2. "You haven't seen me blame somebody else besides me for whatever the challenges are."
The sheriff said he made improvements including creating a database to track inmate complaints. He has also hired a new head of custody and rearranged his command staff.
On Monday, Baca said he would accept the outcome of the FBI investigation, but strongly denied criticisms that abuse was rampant.
The American Civil Liberties Union sued the Sheriff's Department in 2012 saying the sheriff and his top commanders had condoned violence against inmates. The organization released a report documenting more than 70 cases of misconduct by deputies.
A federal jury in October found Baca personally liable for $100,000 for failing to stop inmate abuse by deputies in Men's Central Jail in a case brought by a man who said he was severely beaten while awaiting trial.
The Sheriff's Department also faced recent scrutiny over hiring. The department announced it was reforming hiring practices last month after it was disclosed that 80 deputies had criminal convictions, histories of misconduct or other problem backgrounds. It also gave preferential hiring treatment to friends and relatives of its employees under a special "Friends of the Sheriff" program that allowed top officials to lobby on behalf of applicants, the Los Angeles Times reported.
First elected in 1998 when his incumbent opponent Sherman Block died days before the vote, Baca was re-elected to a fourth term in 2010 and remained a popular figure for much of his time in office.
Less than a year ago he was picked as the nation's Sheriff of the Year by the National Sheriff's Association, which cited his providing educational opportunities for inmates and efforts to work with religious groups.
The group also noted the vast size of the Sheriff's Department and the relatively low crime rates in areas patrolled by deputies.
The Los Angeles County Sheriff's Department is the largest in the United States, with a staff of 18,000 and a budget of $2.4 billion. The agency provides law enforcement services to 42 incorporated cities, 130 unincorporated communities, 10 community colleges, and over 1 million daily commuters of the Metropolitan Transportation Authority and Metrolink.
In addition to serving over 4 million citizens, the Sheriff's Department also serves 42 Superior Courts and 600 bench officers. The Department also manages the nation's largest local jail system, which can house nearly 20,000 prisoners.
