“Brianna had made suicidal comments previously to friends, back in October of this year,” Austin Police Detective Robert Marshall said at a news conference Thursday.

“This continued through the evening of her death, with some self-harming actions early in the evening and a text message to another friend indicating the thought of suicide,” he added.
