Was she taking medication?
Via Baltimore Sun:
Authorities in Harford County were still trying to determine late Thursday why Snochia Moseley opened fire at the Rite Aid warehouse where she had taken a temporary job, killing three employees and fatally wounding herself.
Authorities have not identified the victims.
Troi Coley, a friend of Moseley’s since high school who had stayed in frequent contact with her in Facebook Messenger, said Moseley sometimes felt as if the world was against her but was not an angry person in spite of her alienation.
Coley said she was shocked to learn that Moseley had been named as the person who carried out the shooting.
“She wasn’t a monster, wasn’t an angry person,” Coley said. “I just believe this was emotional distress. If she did this, it was her last straw.”
Harford County Sheriff Jeffrey Gahler said Moseley, 26, was a temporary employee at the warehouse and had reported for work as normal Thursday.
Authorities and court records identified Moseley as female, as did a Facebook profile in her name. But in Facebook messages Coley shared with The Baltimore Sun, Moseley described herself as transgender, although it was not clear whether Moseley preferred to be addressed using masculine or feminine pronouns.
