A man who had a long-running feud with an Annapolis, Maryland, newspaper stormed the paper's newsroom Thursday, shooting and killing five people and wounding two others. 

Jarrod W. Ramos, 39, opened fire with a shotgun shortly after 3 p.m. in the newsroom of The Capital Gazette, police said.

According to authorities, Ramos had sued the newspaper, and after the suit was dismissed, had threatened some working there via social media.

Four people died on the scene and one, a woman, died after being taken to a hospital.

Ramos was charged late Thursday with five counts of first-degree murder. He will go before a judge Friday morning.
