Hartford

A man carrying a backpack with an AR-style pistol inside was arrested Thursday after walking into health insurer Aetna's headquarters in Hartford, Connecticut, with security guards detaining him without incident within minutes. The incident has sparked concerns about safety in the health care industry amid recent high-profile violence.

A white Connecticut police officer was fired on Friday after fatally shooting a man in a mental health crisis last month. The termination came a day after the victim's funeral.
