The family of missing University of Pittsburgh student Sudiksha Konanki has asked police in the Dominican Republic to declare her dead, a police spokesman said Monday.<\/p>\n\n\n\n
Dominican Republic National Police spokesperson Diego Pesqueira said Konanki\u2019s family has sent the agency a letter requesting a declaration of death.<\/p>\n\n\n\n
Konanki, 20, was on spring break with friends in the Caribbean island nation when she<\/a>\u2002<\/a>disappeared<\/a>\u2002<\/a>early\u2002<\/a>March 6<\/a>. Despite an extensive search, her body has not been found.<\/p>\n\n\n\n The Konanki family did not immediately respond to a request for comment Monday night.<\/p>\n\n\n\n Konanki is a junior in biology at the University of Pittsburgh. She is from Loudoun County, Virginia, where her family lives.<\/p>\n\n\n\n Konanki was last seen early March 6 after she went to the beach with friends.<\/p>\n\n\n\n After her friends left the beach, she stayed behind with people she met on the trip<\/a>. She vanished after 4:15 a.m. that day.<\/p>\n\n\n\n The last person thought to have seen Konanki has been identified as Joshua Riibe, 22, a senior at St. Cloud State University in Minnesota who is from Rock Rapids, Iowa.<\/p>\n\n\n\n Dominican authorities confiscated Riibe\u2019s passport Friday as part of an investigation, his attorneys told NBC News.<\/p>\n\n\n\n NBC News spotted Riibe with investigators and his attorney on a beach in Punta Cana early Sunday<\/a>. He was seen pointing toward the sea while a group of security officials kept people away from the area.<\/p>\n\n\n\n Speaking exclusively to NBC News briefly at the resort where Konanki had been staying before she disappeared, and before he was spotted by NBC News on the beach, Riibe said, \u201cI\u2019m just trying to help them out,\u201d adding: \u201cThe ocean is a dangerous place.\u201d<\/p>\n\n\n\n Riibe \u201chas been confined to the hotel since the investigation began. He is permanently escorted by the police anywhere he goes. So no, he is not free to leave,\u201d the law firm representing him said in an email Saturday.<\/p>\n\n\n\n Pesqueira, the national police spokesperson, said no signs of violence were found at the beach.<\/p>\n\n\n\n A hotel spokesperson said red flags \u2014 which indicate \u201cthat the sea had a strong current and very high waves\u201d \u2014 were flying when Konanki disappeared.<\/p>\n\n\n\n
