 Governor Shapiro did also reach out to the families of the critically injured rally attendees. That's Fox's Colonel Scott. The gunman was shot and killed by Secret Service 20-year-old Thomas Matthew Crooks. Investigators are at his home in Bethel Park, Pennsylvania, where Fox's C.B. Cotton reports. Law enforcement sources are telling me the focus is now shifting to gaining access into the shooter's phone. I'm told that federal agents will not feel confident in their assessment that the shooter acted alone until they're able to go in that phone and see who he was communicating with.
