Housemate of alleged Philadelphia mass shooter say he was unraveling days before shooting

Kimbrady Carriker, 40, was arraigned by video conference on 10 sets of charges for 10 victims, including those who were murdered, wounded by gunfire and injured during the chaos. People who lived with Carriker reportedly told the DA's office it was normal for him to keep guns in the house, and wear the ballistic vest, however he was becoming "more and more agitated as the days were passing."
