RIVERSIDE, Calif. -

Veteran homicide prosecutor Mike Hestrin bested his boss -- Riverside County District Attorney Paul Zellerbach -- by nearly 10 percentage points in Tuesday's primary and Wednesday promised to be ``dedicated to ethics'' as the county's next top prosecutor.

With all precincts reporting, Hestrin had about 55 percent of the vote to Zellerbach's 45 percent. About 32,000 mail-in, 5,000 provisional and 2,700
damaged ballots must still be processed, according to the Riverside County
Registrar of Voters.

Hestrin declined to comment extensively Wednesday because ballots remained to be counted, but told City News Service that he would focus on public safety and ``getting back to our core mission.''

``We need a D.A. in office dedicated to ethics ... ethics and integrity have to be the rule and guiding principle,'' he said.

Zellerbach's campaign staff couldn't be immediately reached. In a
statement to The Press-Enterprise, Zellerbach wrote, ``I will certainly do my
best to help Mr. Hestrin in transitioning into becoming the next DA, I am still
concerned about the people in this county as well as all the wonderful, hard-working people that work in the DA's Office.''

The D.A. has been the focus of a criminal probe that culminated in the Indio Police Department asking the California Attorney General's Office to file
felony and misdemeanor charges against him.

Hestrin lambasted the incumbent's character, policies and attitude to
public safety overall during the campaign, while Zellerbach questioned
Hestrin's leadership ability and union allegiances.

In June 2010, Zellerbach, then a Superior Court judge, unseated one-term
D.A. Rod Pacheco in a grueling campaign during which Zellerbach blamed his former friend for clogging the court system due to a no-plea-bargains policy, as well as creating a climate of ``intimidation and fear'' in the D.A.'s office and blowing a hole in the agency's budget.

Zellerbach further alleged that Pacheco was misstating conviction rates to burnish his image, arguing that the 90 percent rate that the then-D.A.
boasted was actually closer to half that.

In March 2013, Hestrin, a 15-year deputy district attorney, announced he
would challenge Zellerbach, citing plummeting morale at the agency, a lack of leadership and concerns over a seeming apathetic response to the fallout from state public safety realignment legislation that critics argue has contributed to a surge in area crime.

Zellerbach, 60, stood by his record of the last four years, using the slogan ``Promises Made; Promises Kept'' in campaign literature. The D.A. insisted that conviction rates increased ``37 percent'' since he took office in January 2011.

However, figures supplied by the Judicial Council of California suggest
otherwise. According to the state agency, in the last fiscal year of Pacheco's
term, 2009-10, the conviction rate was 86.4 percent, while during the first
full fiscal year of Zellerbach's term, 2011-12, the overall rate came to about
84 percent.

Zellerbach has successfully kept a lid on spending at the D.A.'s office, with the budget in the black every year except the first six months of his term, when he assumed control from Pacheco and needed nearly $6 million in
general fund assistance to cover year-end expenses.

The incumbent eliminated 16 executive-level positions almost immediately
after taking office as part of a new budget discipline he vowed to enforce.
However, he eventually hired almost an equal number of people to fill the same top slots. The legitimacy of some hires has been questioned, including the rationale for having a ``tribal liaison'' among the executive staff.

The employee, Ricardo Rubio, was later witnessed allegedly helping Zellerbach conduct campaign activity on county time.

Zellerbach chided Pacheco in 2010 for lowering morale at the agency, citing a grand jury report that suggested some employees feared being demoted
or transferred into static positions if they said anything remotely critical
about how the office was being run.

Zellerbach promised an ``open door'' policy in which opinions could be
shared without fear of retribution. However, line prosecutors have told City
News Service that criticism of Zellerbach is met with hostility and can have
career-killing repercussions.

Shortly after veteran prosecutor John Aki openly criticized personnel changes within the office last year, he was stripped of his seniority in the
Riverside homicide prosecution unit and transferred to a gang unit in Indio.

Hestrin described morale at the D.A.'s office as being ``in the tank,''
pointing to his virtually unanimous vote of support from fellow deputy district attorneys in May 2013 as one example.

The challenger took the incumbent to task on his claims of being a crime
fighter, blasting Zellerbach for supporting mechanisms such as split sentencing, under which a convict can do part of his time behind bars and the rest out of custody, basically on probation.

Zellerbach characterized split sentencing as a ``useful tool'' that provides alternatives to overloading already maxed-out local jails with more
convicts.

Hestrin turned some statistics against the county's top prosecutor, who
boasted of contributing to a ``16 percent'' reduction in violent crime
countywide last year. Zellerbach's reference conveniently ignored some
categories of crime, according to Hestrin, who emphasized the countywide murder rate in 2013 was up nearly 50 percent.

The 43-year-old prosecutor's campaign consistently highlighted the apparent correlation between upward crime spikes and inmate early releases.

According to the sheriff's department, more than 16,200 detainees in the
county's five jails were put back on the street in 2012 and 2013 before their
sentences were served or their cases adjudicated because there wasn't enough space to hold them and at the same time remain in compliance with a federal court decree that each inmate have a bed.

Zellerbach contended that the early releases cannot be attributed to his policies. But Hestrin argued the incumbent's preference for expediting cases
through the system via plea deals and other easy compromises has had an adverse impact on public safety in general.
