Five people were killed during a shooting at the Capital Gazette newsroom in Annapolis, Maryland, local law enforcement confirmed on Thursday.
Law enforcement also confirmed that several others were transported to area hospitals with gunshot wounds.
One person is in custody who is believed to be a shooter at the Gazette building, an Annapolis city spokesperson said.
Phil Davis, a Gazette reporter, tweeted the "gunman shot through the glass door to the office."
The gunman opened fire on multiple employees, Davis said.
“I’m a police reporter. I write about this stuff — not necessarily to this extent, but shootings and death — all the time,” Davis told his own newspaper. “But as much as I’m going to try to articulate how traumatizing it is to be hiding under your desk, you don’t know until you’re there and you feel helpless.”
"There is nothing more terrifying than hearing multiple people get shot while you're under your desk and then hear the gunman reload," he said.
Maryland Gov. Larry Hogan said he was "absolutely devastated to learn of this tragedy in Annapolis."
Anne Arundel police said they are responding to an active shooter at an Annapolis building. Police have evacuated the building where the shooting occurred, authorities said.
The ATF and FBI said they are also responding to a shooting at that location.
The Capital Gazette is owned by The Baltimore Sun.
A single shooter shot multiple people at my office, some of whom are dead.

Gunman shot through the glass door to the office and opened fire on multiple employees. Can't say much more and don't want to declare anyone dead, but it's bad.

Prior to departing Wisconsin, I was briefed on the shooting at Capital Gazette in Annapolis, Maryland. My thoughts and prayers are with the victims and their families. Thank you to all of the First Responders who are currently on the scene.
