A state award presentation is scheduled for Thursday, Nov. 12, following two sergeant promotions in the department.

Southbury police have achieved Tier 3 accreditation, with a state award presentation scheduled for Thursday, Nov. 12. First Selectman Tim O'Neil announced the recognition and two sergeant promotions in the town's update published Tuesday, Nov. 10.

The Connecticut Police Officer Standards and Training Council will formally present the award, according to the update. "Reaching Tier 3 indicates that the Southbury Police Department operates under the gold standard of modern law enforcement accountability, operational transparency, and service quality," O'Neil wrote.

Deondre Pierce was promoted to sergeant following the retirement of Sgt. Duane Manville, according to the update. Sgt. John Jaskolka also retired after 20 years of service. Officer Bailey Cook was promoted to sergeant following Jaskolka's retirement.

The update also reported that security camera installation in town parks is nearly complete. An inventory shortage delayed the equipment, which has since arrived and is being installed. O'Neil noted that residents had asked about cameras following vandalism at Ballantine Park and Settlers Park in November 2025.
