Ethan Nieneker, 32, is accused of gunning down the victims in Austin on Monday afternoon before making a dramatic getaway that involved two stolen cars and a police chase.

Nieneker, who cops had earlier described as having a “mental health history,” ended up being detained with the help of a Taser on the other side of the city.

His mugshot showed blood oozing from a gash under one of his eyes, as well as several scratches across his face.

Nieneker is facing multiple murder charges.
