先进的 DNA 测试和基因组测序帮助拉斯维加斯警方破获一名 16 岁女孩被发现死亡的案件 42 几年前, 调查人员周一宣布.

金·布莱恩特 (Kim Bryant) 于 1 月被报告失踪 26, 1979, after she didn’t return home from school, the Las Vegas Metropolitan Police Department said in a 新闻发布.
Her body was found in a desert area on February 20, 1979, 警察说. Bryant had been sexually assaulted and DNA evidence from a suspect was recovered but police were unable to make an identification, Lt. Ray Spencer with the LVMPD homicide division said during a 新闻发布会 星期一.
      警察 “investigated this case for years without being able to identify a suspect,” Spencer said noting multiple LVMPD detectives had worked to gather new leads.
        DNA evidence from the case was sent to Othram, 公司, a Texas-based forensic sequencing laboratory, for testing and genealogical research following a financial donation from Las Vegas resident Justin Woo, 警察说.
          Ten days ago we were notified that the genological profile built by Othram labs, based on sperm recovered from the body of Kim Bryant at autopsy, revealed that Johnny Blake Peterson was the person that kidnapped, sexually assaulted and murdered Kim Bryant,” Spencer said at the news conference.
          Peterson was a 19-year-old Las Vegas resident at the time of Bryant’s death. “He was never on the radar as a suspect for this murder,” Spencer said.
          Peterson died in January 1993, 警察说.
            Bryant’s father, Edward Elliott, thanked investigators for their work in a statement read by Spencer during the news conference. “Kim was a beautiful girl with a bright future, and it makes me happy that something is being done to help solve cases such as hers,” Elliott said in the statement.
            Woo, whose financial donation made the testing possible, offered his condolences to Bryant’s family during the news conference. “We hope that we provided a little bit of closure for you,” 他说.
