Leadership within the Los Angeles Police Department last week gathered to celebrate the lives of the more than 200 LAPD officers who have lost their lives in the line of duty.

Those men and women, they said, served in different time periods throughout the departments 145+ year history.

LA Mayor Eric Garcetti said the ceremony touched home, especially in light of the deaths of three officers who recently lost their lives in traffic accidents.

Officers Nicholas Lee, Roberto Sanchez and Christopher Corijo all lost their lives in the past 90 days in the line of duty.  Sanchez was killed during a vehicle pursuit; Lee's patrol car was struck by an out-of-control truck, Corijo was killed after his motorcycle was hit by an intoxicated driver.

It's unclear whether that driver is still in custody, or whether she's been released on bail bonds pending trial.

The ceremony kicked off with a video tribute and once that portion of the ceremony concluded, the name of each fallen officer was read aloud.

At the end, a memorial sign was unveiled.  Sources within the LAPD said this is just one of 207 that will be installed throughout the city in the next six months.  Each one will highlight the memory of each fallen officer and will include their contributions to the department.

They will be affixed near the area where each death took place.

If the officer lost their lives while in combat overseas, their corresponding sign will reportedly be placed at the station where they worked.

The LAPD said they will also launch corresponding memorial website in the upcoming weeks.
