A Mexican man who was among three people shot at a Dallas immigration field office last week has died, becoming the second person killed in the attack.

A Latino voting rights group is calling for a federal investigation after its volunteers said Texas authorities raided their homes and seized phones and computers.

Getty Images via CNN(CNN) - The largest US Hispanic civil rights group's national board voted unanimously Friday to urge major manufacturers and retailers to stop selling costumes based on racial stereotypes. The LULAC vote was taken a day after CNN asked the group to respond to photos of costumes sold by Party City, Spirit Halloween, Rubie's Costume Company and on Amazon. CNN affiliate KRQE had earlier reported on shoppers' reaction to a "Mexican Man" costume for sale at a Spirit Halloween store in Albuquerque, New Mexico. "Selling and dressing up in these costumes is just this -- it's racist and unacceptable," Benavides told CNN in an earlier statement. Outrage over similar costumes sold by Spirit Halloween dates to at least October 2009, when the East Bay Times reported on Latino residents of that California community being upset about it.
