A relative called a national FBI phone line in 2016 to report Brian Isaack Clyde was suicidal, a federal official confirmed.
The call was made July 1, 2016, to report Clyde appeared suicidal and had a fascination with guns. Because no threat or specific target was identified, the information was not sent to a local field office, the official said.
Clyde, 22, opened fire on the federal courthouse Monday in downtown Dallas. He was killed during a shootout with federal officers.

The call reporting suicidal behavior was made during the time Clyde served in the U.S. Army.
He was a private first class in the infantry from August 2015 to February 2017, according to the U.S. Army. People who served with him said he was discharged because he couldn't pass a physical fitness test.
Those who knew Clyde described him as a quiet person who kept to himself.
Investigators have not yet said what Clyde's motive for the shooting might have been. Videos of the shooting show Clyde dressed in tactical gear.
He graduated in May from Delmar College in Corpus Christi with an associate's degree of applied science in nondestructive testing technology. College officials said he was an outstanding student.
Clyde attended high school in Austin but had spent time in Dallas, attending Woodrow Wilson High School.

Clyde posted on Facebook about guns, the military, pop culture and cosplay —dressing up as fantasy characters, including in suits of armor, and reenacting battles.
He posted several photos of weapons and videos of himself shooting firearms.
"I have the power of God," he says in one. "I’m going to get you for what you said to me."
