Huh?
The first escorted procession was from the crime scene to the ME office. Then this one from the ME office to the funeral home.
It's a very poorly written sentence that reads as if the four officers were shot by their own PD.
It should read something like:
On Sunday evening, a similar procession of Lakewood officers escorted the four slain officers from Parkland, where the four had been shot, to the Medical Examiner's Office in Lakewood.
