Five people were killed at the offices of the Annapolis Capital-Gazette newspaper Thursday by a gunman who reportedly had a long-running vendetta against the paper. 

Police said the gunman, Jarrod W. Ramos, explicitly targeted the Maryland newspaper after losing a 2012 defamation suit against the company.

Ramos reportedly made numerous derogatory social media postings about the paper and a woman who once accused him of stalking said she told a police official years ago that he would be "the next mass shooter."

An intern at the Annapolis Capital-Gazette, Anthony Messenger, tweeted a cry for help after Ramos opened fire with a shotgun. Messenger survived the attack.

After the attack, the editor of the paper vowed to put a paper out Friday morning and the workers did just that, honoring their slain colleagues. 

The five Gazette staffers killed in the attack were identified as editor Wendi Winters, writer John McNamara, editorial page editor Gerald Fischman, sales assistant Rebecca Smith and assistant editor and columnist Rob Hiaasen.

Anne Arundel County acting police Chief William Krampf called the newsroom shooting a targeted attack in which Ramos "looked for his victims."

Maryland Republican Gov. Larry Hogan Jr. said he is "absolutely devastated to learn of this tragedy" -- which occurred only a few miles from his chambers.

At an evening press conference, Schuh called it a "sad" day in Anne Arundel County, and thanked police for responding within "60 seconds" of the call.

Hogan said that "our thoughts and prayers are with the victims and their families," adding that Anne Arundel and Annapolis city police deserve "serious praise" for their handling of the tragedy.

"The city sends its love ... to the victims of this horrible event," Annapolis Mayor Gavin Buckley (D) said at a press conference.
