but they are the ones they call for help. i love you and i will with never forget you. rest in peace, dad. there is a navigational app who helps people to locate police locations. and it s supposed to be to avoid speed traps but it appears the killer used this to track cops. katey, this app, it s now part of this story because he at least had it and was looking at it. i don t know if it directed him to these cops but what do you think about these apps? we knew he took bus from maryland to new york to assassinate these police officers. were these the officers that were located via the app wave?
