Connecticut is now partnering with neighboring states to share gun crime data.

The governors of New York, New Jersey, Connecticut and Pennsylvania joined together Thursday to sign an agreement to share data.

"We found that, working together, we're a lot more effective," says Gov. Ned Lamont.

For at least five years, Connecticut will share its Deadly Weapon Registry, firearms trafficking task force data and a Special Licensing and Weapons database.

"We want to share information with our neighboring state if someone's on the run. Where are the guns coming from? How are they getting on our streets?" says New York. Gov Kathy Hochul.

The agreement comes as the state has seen a spike in gun violence especially involving teens in the last few months. Lamont says most weapons come from out of state.

"It's all about e-tracing. Going after not just that person with a gun, but the people who are wholesale selling these things - the big guns," he says.

Connecticut State Police can now do one-hour DNA tracing on guns. Courts are adding more judges and sharing more arrest data with each other.

Republicans say it's not enough.

"It's become clear over the last few days that Democrats don't want solutions here. And they continue to blame victims," said state Rep. Craig Fishbein back in August.

Lamont says he's possibly open to a special session.

"If there was something that was urgent and actionable, why not? Our job is to keep people safe," he says.

Lamont says some of the exact details of how it works are still being ironed out.
