The funeral for Chicago Officer Ella French, who was murdered at a traffic stop Aug. 7, was held Thursday morning, with thousands in attendance.

A sea of officers in their dress blue uniforms formed outside St. Rita of Cascia Shrine Chapel as mourners — including city officials and top department leaders—filed slowly inside to remember Officer French, WGN reports.

Outside, a large American flag waved from atop the ladders of Chicago Fire Department trucks.

Adopted as a foster child at the age of one, Officer French leaves behind a mother and brother.

After joining the Chicago PD, French started out in the 10th District before moving to the city’s Community Response Team. On July 1, French helped save the life of a 1-month-old baby who was injured in a mass shooting on the South Side.

Flags in Illinois have been ordered to be flown at half-staff until Thursday evening to remember the life of the 29-year-old officer.
