Mexico City sees its share of protests, but this one was unusual. One woman wept. Other protesters shouted at the tops of their lungs, demanding answers. Still others showed pictures of their relatives to puzzled passersby. The protesters who gathered Thursday are relatives of 11 partygoers who went missing more than a week ago from a bar in a posh Mexico City neighborhood known as Zona Rosa, or Pink Zone. The area has a vibrant night scene with bars, nightclubs and upscale restaurants on every street. The protesters say their relatives were kidnapped on May 26 as they were partying at Heaven, an after-hours bar in the neighborhood. All 11 disappeared between 10 a.m. and noon, they say. The bar is only steps away from Paseo de la Reforma, an iconic avenue in central Mexico City. The emblematic Angel of Independence monument is nearby, as are the U.S. Embassy and the financial district. Guadalupe Dominguez, a relative of one of the missing, said a witness told her the 11 people were kidnapped by armed men who showed up in SUVs, but authorities say there's no evidence of such an incident. A young fellow who managed to escape was the one who told us about it, but we do n't really know anything else, Dominguez said. Mexico reports more than 26,000 missing Most of those hanging out at the after-hours bar were in their 20s, except for Yersi Ortiz, who is 16. Maria Teresa Ramos,
