Connecticut Democrats and advocates were pushing for stricter gun control laws on Monday, which marks the one-year anniversary of the mass shooting in Las Vegas.

It's is also the first day that bump stocks are now illegal in Connecticut. The devices were used by the Las Vegas shooter to fire multiple rounds into the crowd. A total of 58 people were killed and scores more were injured in the attack.

One proposal lawmakers are discussing is to strengthen Connecticut's gun storage laws, which they say has the support of police and prosecutors.

Currently, residents only have to lock and store a gun that is loaded. Proponents want to change that to all guns, loaded or unloaded.

They say the current law often ties prosecutors' hands.

"They say that is very problematic that they would have to prove before a jury that a 4-year-old had access to a loaded weapon," says Jeremy Stein, of CT Against Gun Violence.

The Democrat running for lieutenant governor calling today for even stricter gun laws.

Susan Bysiewicz says Connecticut needs to ban 3D printed guns and so-called ghost guns, which are put together from a kit.

She also wants for tougher gun storage rules.

Her opponent, Joe Markley, is one of 10 Republicans who voted against the new "bump stock" ban in the state Senate.

Neither Markley, nor the GOP candidate for governor Bob Stefanowski returned calls for comment Monday.
