ANNAPOLIS, Maryland, June 29, 2018 (News Wires) - A man with a long grudge against Maryland's capital newspaper was charged Friday with five counts of first-degree murder after police said he shot his way into the newsroom, killing four journalists and a staffer and wounding two others. Jarrod Warren Ramos was swiftly arrested, interrogated and jailed pending a 10:30 a.m. hearing in Annapolis. A court document classified him as "recalcitrant." Investigators said he was uncooperative. A spokeswoman for the public defender's office said she had no comment. Acting Police Chief William Krampf of Anne Arundel County said the gunman "looked for his victims" Thursday in the newsroom of The Capital Gazette in Annapolis. "This person was prepared today to come in, this person was prepared to shoot people," Krampf said. Ramos, 38, has a well-documented history of harassing the paper's journalists. He filed a defamation suit in 2012 that was thrown out as groundless and often railed against them in profanity-laced tweets. Police say surveillance video recorded the attack, which began with a shotgun blast that shattered the glass entrance of the open newsroom. Journalists crawled under desks and sought other hiding places, describing agonizing minutes of terror as they heard his footsteps and the repeated blasts of the weapon. Officers responded in about 60 seconds and arrested him without firing a shot as he too "attempted to conceal himself under a desk," according to his charging documents. They recovered a "long gun firearm" and said he also carried smoke grenades.
