It turns out I'll be moving into my dept's CID in the near future. All of my LE experience to date has been limited to patrol. I'm excited to make the switch, but curious if any experienced investigators here have advice on ways to prepare. I'm obviously expecting to lean heavily on the senior detectives at our dept, as well as our own formal training processes. But I'm curious if are there any books, training materials, courses, etc. that you found helpful when making the switch. I've been reading up lately to try and improve in the areas of interview techniques, writing search/arrest warrants, and death investigations. Any tips (in-thread or PM) would be appreciated!
