Residents of Washington, D.C. rally against President Donald Trump's takeover of city police and use of federal law enforcement.

Tymark Wells, 33, was fatally shot in D.C. hours after President Donald Trump ordered a federal takeover of the city’s police force.

The man accused of killing a police officer while shooting at the U.S. Centers for Disease Control and Prevention (CDC) headquarters in Atlanta had previously been reported to police for suicidal thoughts and launched the deadly attack with his father’s weapons to send a message against COVID-19 vaccines,

The gunman who opened fire Friday at the US Centers for Disease Control and Prevention broke into his father’s safe to get the five firearms recovered at the scene, state investigators said Tuesday, as some CDC workers seeking answers and reassurance from leadership were left dissatisfied by a short agency-wide meeting about the shooting.

In the days since DeKalb County police officer David Rose was shot and killed, Atlanta News First has been learning more about the man who gave his life in the line of duty.
