A gunman opened fire outside a Target store in Austin, Texas, on Monday, killing at least three people and injuring a fourth. The suspect, who fled the scene in a stolen car, is in police custody according to local officials.

The name of the shooter has not been released, but was identified as a white 32-year-old man with a history of mental health issues, said the Austin police chief, Lisa Davis.

An investigation into what unfolded in the Target parking lot and what may have contributed to this act of violence is still underway. Mental illness by itself is not a predictor of violence and only 5% shooting deaths in the US are committed by people with mental health disabilities, according to research from Columbia University’s Department of Psychiatry.

This occurred less than two miles from me, and everyone on the Austin subreddit is clamoring for a motive.
