I wonder if the shooter had enough forethought to turn his phone on airplane mode. If not it should’ve been pinging a nearby tower. I’m sure the FBI has enough prowess to run all those pings and come up with names that may match motive. I’d bet he had social media that may link him. Also hoping there is dna evidence. Pics show him with out gloves
