Other relatives scour hospitals and morgues after the two earthquakes that struck Venezuela on June 24 left more than 1,700 dead and tens of thousands more still missing.Soraida's 44-year-old sister, Rosanna Luna, says not knowing what happened her sister is excruciating."I feel like my hands are tied because I can't find her," she laments.Like Luna, thousands of people are searching for one or more family members with growing desperation six days after the disaster. Social media is flooded with photos of children, the elderly, and couples, along with their names and descriptions, as well as a contact number for their families.The initiative "venezuelatebusca.com," a database launched to help find friends and relatives lost since the earthquakes, reports more than 46,000 missing. The name means "Venezuela is looking for you."The United Nations estimates that the number could be as high as 50,000 but Venezuela's government has avoided putting a number on how many people are still unaccounted for.On Sunday, Luna thought she recognized her sister among the photos of the dead at the main Caracas morgue. One of the faces looked very similar, but when she looked more closely, the toenail polish didn't match. The next day, she returned and found another face that resembled Soraida's in a new batch of photographs. But the person's features were so swollen that she couldn't be sure it was her. Other relatives have been searching for her among the ruins of the apartment where Soraida lived with her dog Princesa in La Guaira, on Venezuela's Caribbean coast, the region worst hit by the earthquakes. But on Monday, as they were returning to the site, a strong aftershock forced them to abandon their search. "It's harder not knowing, because you ask yourself, 'What do I do? Where do I look for her?" Luna cried. "I look for her here and she's not there, I went to the hospital and she's not there. Where is she?'" "Very painful"
