(美国有线电视新闻网) 6 岁的琼贝妮特拉姆齐 (JonBenet Ramsey) 被谋杀震惊全国已有 25 年，现在科罗拉多州博尔德市的调查人员表示，他们已经分析了近 1,000 个 DNA 样本以找到凶手。
这是一系列数字中的最新一个，显示了他们正在进行的努力：
警方已收到、审查或调查了 21,000 多封举报、信件和电子邮件。
侦探们已经前往了 19 个州。
他们采访了1000多人。
他们已经处理了1500多件证据。
尽管如此，此案仍未解决。它抓住了公众的利益，可能是由于多种因素，包括她参与为年轻女孩举办的选美比赛、她的家庭财富以及对她父母的怀疑，他们从未受到指控，后来通过 DNA 检测被当局清除。
1996 年 12 月 26 日，JonBenet 在博尔德家中失踪。她的母亲 Patsy 告诉警方，她发现了一张赎金纸条，要求 118,000 美元让女孩归还。
那天，她的尸体被发现在家中的地下室。
警方后来透露她的头骨已经骨折。
Patsy Ramsey 于 2006 年死于卵巢癌。
在纪念谋杀案 25 周年的声明中，博尔德警方表示，他们积极“使用新技术加强调查”，并定期检查 DNA 匹配以解决此案。
“由于 DNA 技术的巨大进步，多个嫌疑人已通过系统检查匹配。CBI（科罗拉多州调查局）已使用最新的 DNA 技术更新了 750 多个参考样本。博尔德警察局与 CBI 密切合作关于未来 DNA 的进步。”
25 years after JonBenet Ramsey killing, investigators have tested almost 1,000 DNA samples
(CNN)It's been 25 years since the murder of 6-year-old JonBenet Ramsey riveted the nation, and now Boulder, Colorado, investigators say they have analyzed almost 1,000 DNA samples to find the killer.
It is the latest in a string of numbers that reveal their ongoing efforts:
Police have received, reviewed or investigated more than 21,000 tips, letters and emails.
Detectives have traveled to 19 states.
They have interviewed more than 1,000 people.
They have processed more than 1,500 pieces of evidence.
Still, the case remains unsolved. It seized the public interest, due perhaps to a mix of factors, including her involvement in beauty pageants for young girls, her family's wealth, and suspicion around her parents, who were never charged and later cleared by authorities through DNA testing.
On December 26, 1996, JonBenet was reported missing from the family's Boulder home. Her mother, Patsy, told police she found a ransom note demanding $118,000 for the girl's return.
Her body was found that day in a basement room of the home.
Police later revealed her skull had been fractured.
Patsy Ramsey died of ovarian cancer in 2006.
In a statement marking the 25th anniversary of the murder, Boulder police said they actively "use new technology to enhance the investigation" and check regularly for DNA matches in order to solve this case.
"Thanks to the huge advances in DNA technology, multiple suspects have been run through the system to check for matches. CBI (Colorado Bureau of Investigation) has updated over 750 reference samples with the latest DNA technology. The Boulder Police Department works closely with CBI on future DNA advancements."
