"It is never really over", McCarthy said.
At least five people were killed and several others injured on Thursday (Jun 28) when a gunman opened fire inside the offices of the Capital Gazette, a newspaper based in Annapolis, a historic city an hour east of Washington.
Investigators are reviewing Ramos' social media postings and searched his apartment, where Altomare said they found evidence of the planning Ramos had put into the attack.
Ramos, 38, appeared by video at a county district court accused of murdering five people at the newspaper as part of a years-long feud that began when it reported on his harassment of a woman. The defamation case was dismissed.
Capital Gazette columnist Terry Smith claimed the newsroom was vulnerable to an attack.
Police are checking the building in Annapolis for explosives and whether more than one suspect was involved, Anne Arundel County police spokesman, Lieutenant Ryan Frashure, told reporters.
Ramos filed a lawsuit, which was later thrown out, against McCarthy in 2014. And "he knew how to walk the line" between frightening people and threats that could land him in jail.
Over a four-year span, from late 2011 to early 2016, Ramos waged a social-media campaign against the Capital Gazette.
CBS News spoke to Thomas Marquardt, who was the paper's editor and publisher at the time, when the paper was at a different location. A year later he tweeted the names of two Capital staffers whom he said he would like to see "cease breathing". Prosecutor Wes Adams said Ramos carefully planned the attack, barricading the back door and using "a tactical approach in hunting down and shooting the innocent people". Police have identified the five people killed in the shooting as the paper's assistant managing editor Rob Hiaasen; editorial page editor Gerald Fischman; features reporter Wendi Winters; reporter John McNamara, and sales assistant Rebecca Smith. The shootings were one of the deadliest attacks on reporters in US history.

"Today, we are speechless", the newspaper wrote on its editorial page, which was left nearly entirely blank to "commemorate victims of Thursday's shootings at our office". He said nothing and was expressionless.
Brennan McCarthy, the lawyer who represented the woman Ramos harassed, told CBS, "He was as angry an individual as I have ever seen".
Chase Cook, another of the paper's reporters, said Thursday that the shooting would not stop the daily from going to press. Some told about their personal experiences during the shooting.
The alleged gunman who killed five people at a Maryland newspaper was investigated in May 2013 after threats were made against the paper, police said on Friday.
"That fellowship changed my life and my family's life", Penn said.
"This attack shocked the conscience of our nation and filled our hearts with grief", Trump said at the outset of an event at the White House marking the passage of the Republican tax plan six months ago.
"Journalists like all Americans should be free from the fear of being violently attacked while doing their job". He has also repeatedly referred to the media as "Fake News" and has also called the media "the opposition party in many ways".
Maryland Governor Larry Hogan said he is grief-stricken, and urged members of the public to stay away from the area.
The original Gazette article was titled "Jarrod wants to be your friend", which detailed Ramos' abuse of his former high school acquaintance after friending her on Facebook in 2009.
