Spring will be a season of change for the Darien Police Department. New Chief of Police Ray Osborne was formally sworn into duty on Wednesday, March 15 and announced three more promotions within the department on two days later. Lieutenant John P. Lawlor was promoted to the rank of captain, Sergeant Jeremiah P. Marron Jr. was promoted to the rank of lieutenant, and Detective Nicholas Aranzullo was promoted to the rank of sergeant.

Osborne is the tenth chief in the Darien Police Department’s 92-year history; he replaces Duane Lovello, who retired on February 15. During a ceremony shared with family, friends, fellow law enforcement and town officials at Town Hall, Osborne said he will would be looking to find the Darien Police Department’s next generation of leadership.

The chief thanked his wife Susan and his three children Amanda, Christie and Ray for their support, acknowledging the stress that a career in law enforcement can bring to a household.

“The hours, the odd shifts, the stress, the missed holidays and birthdays and everything else that goes with this job takes a huge toll on family life sometimes and I’m so fortunate that I have such a great, supportive family,” Osborne said. “I know that Amanda and Christie have very fond memories of reading the promotional test quiz books to me when they were about nine or 10-years-old.”

Darien’s new police chief thanked the people of the town for being gracious and welcoming, even as the job of police grows more demanding. Osborne also acknowledged Lovello for his service, saying the former chief brought the department “into the 21st century.”

“A great leader grows as things change, and things are surely changing in police work, every single day,” Osborne said.

Darien’s police commission appointed Osborne, a 33-year, veteran of the department, on Feb. 1. During the ceremony Commission Chairman J. Paul Johnson said their choice follows the tradition of promoting within the department ranks, hinting at the promotions that were announced on Friday. First Selectman Jayme Stevenson said Osborne’s appointment provides “wonderful continuity” to the department.

“We are so blessed in our town to have an exemplary cadre of law enforcement professionals and a terrific police commission to guide them,” Stevenson said.
