AUSTIN, Texas (AP) — A random shooting outside a Target store in Texas began when a gunman killed an employee collecting shopping carts then a man and his 4-year-old granddaughter, sparking a chaotic hour of stolen cars and crashes that ended with him arrested naked holding a Bible, police said Tuesday.

The victims of suspected shooter Ethan Nieneker, 32, who opened fire at a Texas Target Monday afternoon, have been identified, police say

The motive behind Nieneker's decision to start shooting outside the store shortly after 2 p.m. is still unclear.
