ORANGE >> Whether officers are learning new skills or brushing up on old techniques, the New Haven Police Department decided it was time for detectives to train regularly in partnership with other area departments on a regular basis.

Friday concluded the weeklong detective school for the New Haven Police Department, but for the first time, the course was intentionally open to officers from neighboring departments, said Lt. Herbert Johnson. The training is hosted at the University of New Haven campus in Orange.

“I wanted to move forward with a regional school,” Johnson said, adding he hopes to host the school twice a year. “We opened it up (this year) to all of our partners.”

The detective school, a training course for old and new detectives, has been running for many years, he said. Friday’s graduating class consisted of 30 officers, some new to detective work and some veterans. Rather than the detective schools that are typically offered after promotions, this week was meant to bring officers from all over the region together to train and learn new skills.

Other departments present at the detective school this week included East Haven, Cheshire, Meriden, Waterbury, Naugatuck, Hamden, Madison, Clinton, Guilford, state police, and Yale University Police.

Including officers from other departments in the detective school is really important for networking and building relationships for when they will be really be important, Johnson said.

“Nowadays, information sharing is key,” Johnson said. “Our burglars, robbers, our shooters, go into surrounding towns.”

“It’s very important to network because our cases do overlap,” he said.

Classes were taught in partnership with UNH, the state’s attorney’s office, and Dr. James Gill, the state medical examiner also taught a class. The most popular training is interview and interrogation techniques, said Lisa Dadio, a retired lieutenant from the New Haven Police Department which she said is “my heart and my home,” and now a lecturer in the forensics department at UNH.

“It’s fascinating and the detectives love it,” Dadio said. “The feedback is so positive.”

Dadio said the interrogation class, taught by Charles Morgan III, an associate professor of national security studies at UNH, spanned two days of the detective school this year.

Dadio taught the crime scene investigation class, she said, and that included detectives working at a mock crime scene in a crime scene house operated by UNH.

Dadio said it was important for detectives to have this networking opportunity so crimes can be solved quicker in the future. Meeting the state medical examiner and the state’s attorneys is also good for the detectives, Dadio said, as it will help with the efficiency of investigations moving forward.

“Crime doesn’t know city boundaries,” she said. “You have to establish relationships outside of your own department.”

Just before the officers received their certificates for their participation Friday, New Haven Assistant Chief Achilles Generoso thanked the men and women for their time and attention and encouraged all of them to come to regular daily intel briefings in New Haven and to keep in touch with UNH professors and one another.

“I personally feel detectives have one of the most important roles in the police department,” Generoso said. “You guys solve crimes... We want to encourage cooperation and collaboration.”
