Another shooting has taken place, this time at the Capital Gazette building in Annapolis, MD.

UPDATE: Police have now entered the investigative phase and are in the process of securing the shooter’s Maryland residence and preparing for search warrants.

Staff at the offices said the suspect opened fire through a glass door into the newsroom. Four victims died at the scene and another died at a local hospital.

More than 170 people were evacuated from the building, which was home to several local newspapers and other businesses.

Bill Krampf, deputy police chief Anne Arundel county, told reporters: “There’s five fatalities that we know of. There’s several other persons that are gravely injured.”

Police found the suspect hiding under a desk at the site and have apprehended him in custody and have now identified hm.

Earlier reports said he was not co-operating with authorities and had apparently taken measures to disfigure his fingerprints. He has been described as a white male in his late 30s.

The shooter used a “long gun” in the attack. Authorities also recovered what they initially believed was an explosive device at the scene, but it was later found to be canisters of smoke grenades.

Krampf also said the building had been “tactically secured” by a SWAT team and quick responders. It will remain closed to the public while criminal investigators scour the site. Officers from the Federal Bureau of Investigation are also on the scene.

Counterterroism units were closely monitoring the events but at present, the crime is not being treated as a terrorist attack.

Larry Hogan, Governor of Maryland, said: “It’s a tragic situation. We don’t have all the information yet, and we can’t give all the information yet, but we have had several fatalities. We thank the people that came in and kept it from being worse. The response time was incredible.”

Anne Arundel County Executive Steve Schuh was heartbroken over the shooting.

“Those fatalities are so sad,” he said. “I don’t know what to say other than our thoughts and prayers are with them and their families.”

US President Donald Trump has been briefed on the shooting. He tweeted: “My thoughts and prayers are with the victims and their families.”

“We are putting out a damn paper tomorrow”

Remarkably, staff at the paper are determined to keep working. Jimmy DeButts, editor of the Capital Gazette has outlined the passion he and his staff have for journalism and for serving the local community in a series of tweets.

Reporter Chase Cook wrote: “I can tell you this: We are putting out a damn paper tomorrow.”

In the wake of the horrific events, the newspaper’s website published a story detailing how the paper is one of the oldest in the US, dating back some 134 years. Its origins go back even further as it evolved from an earlier paper which was established in 1727. It was also the first newspaper in the nation to be published by a woman.

Phil Davis, a courts and crime reporter at the Capital Gazette offered a harrowing commentary on the unfolding events.

Congressman Dutch Ruppersburger said the journalists at the paper “perform an invaluable community service,” and said he was praying for them.

Ongoing gun violence in the US

The Maryland attack was just the latest high-profile mass shooting in the country. On 14 February, 17 people were fatally shot at Marjory Stoneman Douglas High School in Parkland, Florida in an attack that sparked a youth-led movement to end gun violence. The Parkland shooting launched a youth-led movement for gun control.

On 22 April, four people were killed in a shooting at a Waffle House in Nashville, Tennessee.

The National School Walkout social media account tweeted that the Maryland shooting is the 195th instance of a mass shooting in the US this year.

Police officers were guarding the offices of the Baltimore Sun (the parent company of Capital Gazette) and media outlets in and around New York as a precautionary measure in the hours after the attack.
