John Idleburg being sworn in as Lake County sheriff by Chief Judge Ukena Saturday morning.

Democratic candidate John Idleburg, who beat incumbent Mark Curran by 137 votes, was sworn in Saturday morning as the new Lake County sheriff.

Lake County Circuit Court Chief Judge Jay Ukena swore in Sheriff Idleburg at a private ceremony at the Lake County Courthouse. Idleburg’s opponent, Mark Curran, who was running for re-election, lost by 137 votes. Idleburg had 50.03 percent of the votes and Curran had 49.97 percent out of 245,633 votes tallied.

“I am honored to serve as your Lake County Sheriff and am grateful to the citizens of Lake County for putting your trust in me to lead Lake County’s largest law-enforcement agency,” Idleburg said.

“We have an exciting future ahead of us, and I look forward to working alongside the great men and women of the Lake County Sheriff’s Office,” Idleburg added.

Lake County Sheriff Spokesman Christopher Covelli called Idleburg a service-driven individual. He previously served in the U.S. Marine Corps and then served for over 30 years as a law enforcement officer at local and federal levels.

“He brings a wealth of professional community service experience to lead the Lake County Sheriff’s Office,” Covelli said.

A ceremonial swearing-in will take place at 8 a.m. on Monday in Ceremonial Courtroom T810. The public is welcome to attend, Covelli said.
