As part of National Police Week, San Antonio Police Department and Bexar County Sheriff's Department are honoring their slain officers and deputies.
SAPD held a ceremony earlier this week and Sheriff Susan Pamerleau will hold a special candlelight vigil Thursday evening for members of her department - the first time Bexar County has held such a private event.
On Friday deputies will gather for the annual public ceremony, where Sgt. Yvonne Vann, wife of Sgt. Kenneth Vann, who was shot and killed while on duty in May 2011, will speak.
The public event will feature a "roll call of the fallen," a traditional shotgun salute, taps, and a children’s choir from Canyon Ridge Elementary.
Dignitaries from The U.S. Marshall’s Service, U.S. Secret Service, SAPD, and other law enforcement and government agencies will be in attendance.
Since 1840, 19 Bexar County deputies have died in the line of duty.
