The parents of an Indian-born student from a U.S. university who went missing earlier this month from a popular tourist resort in the Dominican Republic have asked police to declare their daughter legally deceased, according to a letter released by a police source on Monday. Sudiksha Konanki, a 20-year-old pre-med student at the University of Pittsburgh, went missing on March 6 - two days before an international day of activism for women's rights - during a spring break trip to Punta Cana. "Following an extensive search, Dominican authorities have concluded that Sudiksha is believed to have drowned ... the individual last seen with her is cooperating with the investigation, and no evidence of foul play has been found," the letter said.
