The gunman who killed five people in the Capital Gazette newspaper building has been identified as Jarrod Ramos, according to CBS News. Police have not confirmed his identity.
Ramos, who lives in Laurel, Maryland, has a criminal conviction in his past, including criminal harassment.
According to an article written by the Capital Gazette in 2011, Ramos started talking on Facebook with a woman he went to high school with. At some point, she said he began harassing her. He was charged and pleaded guilty to harassment.
The Capital Gazette then wrote a story about the woman, Ramos and the dangers of what you post online. The article was called "Jarrod wants to be your friend."
Almost a year later, Ramos filed a defamation lawsuit against the newspaper, the writer and the publisher.
He also has various other criminal and civil cases in Anne Arundel County, Annapolis, Prince George’s County and Howard County.

The caption along with the tweet reads “So fortuitous having an open mic to go outside the record in the Court of Appeals. And they think *you're* stupid!?”
