Man taken into custody after threatening to shoot up Alexandria courthouse in murder/suicide

A Washington D.C. man was placed under an emergency substantial risk order on March 16 after allegedly threatening to shoot up the Alexandria Courthouse (520 King Street).
Police found the man outside of the courthouse in his red Jeep Cherokee, after his ex-girlfriend called police and said that he was having a mental health crisis, according to a search warrant affidavit. The woman told police that her ex was triggered after being threatened by a woman with a knife the previous day.
In a text message, the man told his ex that he was “outside the courthouse with my guns,” and when she asked his intentions, he responded with, “murder suicide,” according to the search warrant. She also told police that he suffers from depression and other mental health illnesses, and has never sought treatment.
The woman then sent police screenshots of texts from the man, including one that read, “I guess but at least my name will be on the news or sumn.”
Police spoke to the man on the phone, who told them he had disassembled rifles in bags in his trunk. He was not charged with a crime, and was taken into custody and transported to Inova Alexandria Hospital.
