Questions remain after tragedy near Texas shelter for people fleeing crises

Witnesses says a driver yelled slurs towards those outside the shelter after driving into a group of people, killing eight

Neighbors held a small vigil Sunday night on a dirt path along a busy road in Brownsville, at the eastern end of the US-Mexico border, where eight people were killed and 10 were injured at a bus stop that morning.

A small display of flowers and a row of candles grew as shaken people visited the dimly lit curb where the appalling crash occurred.
