This gun and ammunition theft is one of six in the Bay Area since Nov. 2015.

The weapon used to kill 32-year-old Kate Steinle on Pier 14 in July 2015 was stolen from a Bureau of Land Management ranger's car along the Embarcardero.

Just last week, the ranger testified in court that he felt comfortable leaving the gun in his SUV with tinted windows.

Last year, California lawmakers passed a law requiring law enforcement officers to lock firearms in safe boxes in their vehicles.

Senator Jerry Hill sponsored the legislation and spoke with us about it in Sept. 2016, "It's the responsibility of that officer to make sure that it is secure and safe," he said.

On Saturday night, Hill's office clarified that the senator's law only applies to handguns, not the long guns that were stolen on Friday night.

Issues have persisted since that law was signed.

In September, an off-duty San Francisco's Sheriff's deputy reported his car was broken into and guns stolen on San Bruno Avenue in Potrero Hill. That officer was later fired.
