Capital Gazette shooting

Jarrod Ramos, the man accused of killing five Capital Gazette staff members when he allegedly brought a shotgun into their Annapolis, Md., newsroom and opened fire, has pleaded not guilty to all 23 counts against him.

Ramos is charged with the murders of John McNamara, Gerald Fischman, Rob Hiaasen, Wendi Winters and Rebecca Smith on June 28.

"Gunman shot through the glass door to the office and opened fire on multiple employees," reporter Phil Davis tweeted at the time.

President Trump has ordered U.S. flags to be lowered to half-staff as "a mark of solemn respect" for the four journalists and a newspaper sales representative killed last week at the Capital Gazette newsroom in Annapolis, Md. The proclamation came after Annapolis' mayor said his request to lower flags had been denied.
