PARKLAND, Fla. (Reuters) - The 19-year-old man accused of shooting 17 people to death at a Florida high school legally purchased the assault rifle used in the killings and may have foreshadowed the attack in a social media comment investigated by the FBI last year, authorities said on Thursday.
New details about the troubled background and gun ownership of the suspect, Nikolas Cruz, emerged as he appeared in court to face formal charges of carrying out the second-deadliest mass shooting at a public school in U.S. history.
