At least five people were killed and several more injured when a gunman opened fire Thursday afternoon in a shooting deliberately targetting the offices of the Capital Gazette newspaper in Annapolis, Md. 

A report on the paper's web site identified the suspect as Jarrod W. Ramos, a 38-year-old Laurel, Md. man, citing law enforcement sources familiar with the investigation. Ramos had a longstanding dispute with the paper, stemming from a failed defamation suit in 2012, according to the report. 

"This was a targeted attack on the Capital Gazette," Anne Arundel County Deputy Police Chief William Krampf said, according to the report on the paper's web site. "This person was prepared today to come in. He was prepared to shoot people."

The suspect reportedly had altered his fingerprints in an apparent attempt to prevent identification, the paper reported, citing an unnamed law enforcement source. Threats against the paper had been made on social media in recent days the report said. 

At an earlier press conference Krampf said that the shooter was using a "long gun" when he started firing on the newsroom. He confirmed that there was no gunfire exchanged between police and the suspect. Police also recovered a suspected explosive device.

Anne Arundel County Executive Steven Schuh confirmed that there have been at least five fatalities and several injuries as a result of the shooting. 

The Capital Gazette is affiliated with the Baltimore Sun which is owned by Tronc Inc. (TRNC) .

Gazette reporter Phil Davis tweeted that a single shooter shot through the glass door to the office and that some of his colleagues were dead, though the fatalities have not yet been confirmed by authorities. 

Police were called to the scene at 2:40 PM ET to respond to the active shooter situation.

President Trump, a frequent critic of the media, took to Twitter to offer condolences. 

The NYPD announced that it's sending officers to media outlets around New York City. The LAPD is also sending officers to media outlets around Los Angeles.
