针对被控杀害保守派活动人士查理·柯克的男子的预审于周三下午重新开庭，辩方律师对DNA检测的可靠性提出质疑，检方称该检测结果将被告与疑似作案凶器联系在了一起。检方同时披露，嫌疑人的室友已获得豁免，以换取向调查人员提供该案的录音视频证词。
检方试图说服州地区法官托尼·格拉夫，称其有足够证据以加重谋杀罪对泰勒·罗宾逊提起公诉。预计庭审将于周五结束，之后格拉夫将裁定案件是否进入审判程序，专家表示这大概率会通过。
23岁的罗宾逊被控在9月10日犹他谷大学校园的刺杀行动中犯下加重谋杀罪，检方正寻求对其判处死刑。罗宾逊在因柯克枪击案被捕前无任何犯罪前科。
罗宾逊尚未认罪。其律师未就其有罪或无罪发表评论，但他们一直在试图排除死刑判决，目前尚未成功。
州调查人员称，罗宾逊的室友以提供证词为交换获得豁免
犹他州调查局特工布莱恩·戴维斯在周三的预审庭审中表示，兰斯·特维格斯因提供证词而获得了“使用豁免”，这意味着检察官已同意不会在刑事案件中使用这些证词指控特维格斯。
戴维斯告诉法庭，特维格斯于4月20日接受了询问并被录音，此举替代了将其室友作为证人带到预审庭审现场。
犹他县副地方检察官劳伦·亨特表示，她预计辩方团队会对法庭上引入该录像证词提出异议，并在向法官说明时解释了她认为该证据应被允许采纳的理由。
亨特还称，辩方团队在最后一刻提出了多项修改删减内容的要求。但她表示，对视频进行删减是一项复杂工作，如果辩方团队确实希望删减内容，本应更早提出申请。
戴维斯周三表示，特维格斯在调查期间接受了两次询问。
戴维斯告诉法官，9月12日的第一次询问有两名联邦调查局特工在场。戴维斯称，第二次询问于4月20日进行，当时包括他在内的多名执法人员和检察官在场。
犹他县副地方检察官劳伦·亨特周三似乎正在奠定基础，争取将特维格斯证词的录音作为证据提交。
根据当局去年9月提交的法庭文件，罗宾逊在枪击案发当日与特维格斯的短信中承认了自己的罪行。
案发时，两人同住在美国犹他州西南部圣乔治市的一套公寓内。
法庭文件显示，罗宾逊的室友据称在公寓里罗宾逊电脑的键盘下发现了一张纸条，上面写着：“我有机会除掉查理·柯克，我会这么做的。”
在短信交流中，当特维格斯询问罗宾逊是否是枪击柯克的枪手时，罗宾逊回复道：“是我，我很抱歉。”法庭文件如此记载。
罗宾逊的室友向调查人员提供了DNA样本
联邦调查局分析师阿曼达·巴克表示，在罗宾逊的室友提供DNA样本用于比对后，她得以重新进行检测，并将所有DNA痕迹归于两人。
调查人员在柯克遇刺地点附近的林区发现了一条毛巾和疑似作案凶器——一把带有一发已发射弹壳的栓动步枪。
犹他州调查局的珍妮弗·福穆伊纳作证称，毛巾上的DNA匹配到了两个人。其中一人是特维格斯，另一人极有可能是罗宾逊。
特工描述罗宾逊自首当晚的情况
犹他州调查局特工布莱恩·戴维斯播放了华盛顿县警长办公室的一段视频片段，内容是泰勒·罗宾逊在查理·柯克遇刺次日自首的画面。
戴维斯在周三的预审庭审中表示，视频片段显示罗宾逊站在警长办公室的一个房间里，身穿T恤和棒球帽。
戴维斯告诉犹他县副地方检察官劳伦·亨特，罗宾逊和其父母接受询问后，罗宾逊被逮捕。当局此前曾表示，罗宾逊的父亲从枪击嫌疑人的监控照片中认出了自己的儿子，并说服儿子自首。
戴维斯称，他询问了罗宾逊的母亲，其他执法人员则询问了罗宾逊和罗宾逊的父亲。戴维斯在证词中表示，与罗宾逊一家一同前来的一名家庭友人也接受了询问。
这段视频片段是连日庭审中提交的、用于裁定案件是否进入审判程序的多段证据之一。
法医专家称DNA检测“极其可靠”
法医专家劳伦斯·夸里诺表示，执法机构使用“极其可靠”的检测方法来确定某人与犯罪现场发现的DNA匹配的概率。
夸里诺是宾夕法尼亚州锡达克里斯特学院法医科学项目的教授兼主任，他将DNA检测称为法医科学的“黄金标准”。
泰勒·罗宾逊的一名律师周二对检方所称的将他与疑似作案凶器关联的DNA检测可靠性提出了质疑——该凶器是一条裹着毛巾的步枪，在查理·柯克遇刺后被发现。
夸里诺指出，存在对DNA证据提出质疑的方式。例如，他说辩护律师可以声称DNA物质是通过一名与嫌疑人握过手的中介转移到现场的。但他表示，负责分析DNA的政府实验室有着严格的质量控制，其科学依据是可靠的。
不过，辩护律师迈克尔·伯特试图对分析师的结论提出质疑。
“她无法将罗宾逊先生与存疑的样本匹配起来，”伯特总结道。
犹他县副地方检察官瑞安·麦克布赖德反驳称，如果案件进入审判程序，可以对DNA检测的可靠性进行审查。他表示，预审阶段并非讨论此事的合适时机。
“关键在于，这些解释存在多种不同的解读和争议空间，”麦克布赖德说。“法院将在审判阶段确定其是否达到可靠性门槛。”
柯克和罗宾逊的父母均出席了预审庭审
查理·柯克的父母于周三抵达法院，参加预审庭审的恢复审理。
罗伯特和凯瑟琳·柯克至今每天都出席了预审庭审。不过有时他们会离开法庭，以免听到有关儿子死亡的细节。
不久之后，泰勒·罗宾逊的父母也抵达了法院。马特和安珀·罗宾逊至今每天都出席了庭审，通常坐在法庭旁听席上与柯克一家相隔一两排的位置。
Roommate of suspect in Charlie Kirk’s assassination given immunity in exchange for recorded statements

The preliminary hearing for the man charged with killing conservative activist Charlie Kirk resumed Wednesday afternoon, with defense attorneys questioning the reliability of DNA testing that prosecutors say links the defendant to the suspected murder weapon. Prosecutors also revealed that the suspect’s roommate was given immunity in exchange for providing recorded video statements to investigators about the case.
Prosecutors are trying to convince state District Judge Tony Graf that they have enough evidence to bring Tyler Robinson to trial on an aggravated murder charge. After the hearing concludes, which is expected to happen Friday, Graf must determine if the case should proceed, which experts say is likely.
Robinson, 23, is charged with aggravated murder in Kirk’s Sept. 10 assassination on the Utah Valley University campus, for which prosecutors are seeking the death penalty. Robinson had no prior criminal record before his arrest in Kirk’s shooting death.
Robinson has not yet entered a plea. His attorneys have not commented on his guilt or innocence. They have, however, sought to get the death penalty taken off the table, so far unsuccessfully.

Robinson’s roommate was given immunity in exchange for statements, state investigator says
State Bureau of Investigation Agent Brian Davis said at Wednesday’s preliminary hearing that Lance Twiggs was given “use immunity” for Twiggs’ statements, meaning a prosecutor has agreed not to use those statements against someone in a criminal case.
Twiggs’ April 20 interview was conducted and recorded in lieu of bringing the roommate to the preliminary hearing as a witness, Davis told the court.
Deputy Utah County Attorney Lauren Hunt said she expects the defense team to object to the introduction of the videotaped statements in court, explaining to the judge when she thought the evidence should be allowed.
Hunt also said the defense team proposed multiple redactions at the last minute. But she said redacting a video is complicated and that the defense team should have requested redactions sooner if it had wanted them.
Twiggs was interviewed twice as part of the investigation, Davis said Wednesday.
Two FBI agents were on hand for the first interview on Sept. 12, Davis told the judge. The second interview was April 20, Davis said, and he was one of several law enforcement agents and prosecutors present.
Deputy Utah County Attorney Lauren Hunt appeared to be laying a foundation Wednesday, seeking to get a recording of Twiggs’ statements introduced as evidence.
According to court documents filed by authorities last September, Robinson admitted in a text message with Twiggs on the day of the shooting that he had committed the crime.
At the time of the slaying, the two shared an apartment in St. George, a city in southwestern Utah.
Robinson’s roommate allegedly found a note under the keyboard of Robinson’s computer in the apartment that read, “I had the opportunity to take out Charlie Kirk and I’m going to take it,” the court documents stated.
In the text exchange, when Twiggs asked Robinson if he was Kirk’s shooter, Robinson replied, “I am, I’m sorry,” the court documents stated.
Robinson’s roommate provided investigators with DNA sample
FBI analyst Amanda Bakker said after Robinson’s roommate provided a DNA sample for comparison, she was able to rerun her tests and attribute all of the DNA to two people.
Investigators found the towel and suspected murder weapon — a bolt-action rifle with one spent round — in a wooded area near where Kirk was shot.
DNA on the towel matched to two people, Jennifer Faumuina with the State Bureau of Investigation testified. One was Twiggs, and the other was very likely Robinson, she said.
Agent describes the night Robinson surrendered
State Bureau of Investigation Agent Brian Davis narrated a video clip from the Washington County Sheriff’s Office, where Tyler Robinson turned himself in the day after Charlie Kirk’s shooting.
Davis said at a preliminary court hearing Wednesday that the video clip shows Robinson standing in a room at the sheriff’s office. Robinson is wearing a T-shirt and a baseball cap.
Davis told Deputy Utah County Attorney Lauren Hunt that after Robinson and his parents were interviewed, Robinson was placed under arrest. Authorities previously said that Robinson’s father had recognized his son from surveillance photos of the shooting suspect and convinced his son to turn himself in.
Davis said he interviewed Robinson’s mother, and that other law enforcement officers interviewed Robinson and Robinson’s father. A family friend who came in with the Robinsons also was interviewed, Davis said in testimony.
The clip was one of several presented over days of hearing testimony to decide if the case should proceed to a trial.
Forensics expert describes DNA testing as “extremely reliable”
Forensics expert Lawrence Quarino said law enforcement agencies use “extremely reliable” tests to determine the probability a person matches with DNA found at a crime scene.
Quarino, a professor and director of the forensic science program at Cedar Crest College in Pennsylvania, called DNA testing “the gold standard” of forensic science.
A lawyer for Tyler Robinson on Tuesday questioned the reliability of DNA tests authorities said have linked him to the suspected murder weapon – a rifle found wrapped in a towel after Charlie Kirk was shot.
There are ways to challenge DNA evidence, Quarino noted. He said a defense attorney, for instance, could claim DNA material was transferred to a location by an intermediary who shook the hand of a suspect. But he said government labs that analyze DNA have strict quality controls and their science is sound.
Defense lawyer Michael Burt, however, sought to cast doubt on the analyst’s conclusions.
“She can’t match Mr. Robinson to the questioned samples,” Burt concluded.
Deputy Utah County Attorney Ryan McBride countered that the reliability of DNA testing could be examined if the case goes to trial. He suggested the preliminary hearing was not the time to take up the matter.
“The point is there are explanations that are susceptible to different interpretations and arguments,” McBride said. “The court is going to determine if it meets the threshold of reliability at trial.”
Parents of both Kirk and Robinson attend preliminary hearing
Charlie Kirk’s parents arrived at the courthouse for the resumption of the preliminary hearing Wednesday.
Robert and Kathryn Kirk have attended every day of the preliminary hearing so far. Sometimes, however, they have left the courtroom to avoid hearing details about their son’s death.
A short while later, Tyler Robinson’s parents arrived at the courthouse. Matt and Amber Robinson have attended every day of the hearing so far, usually seated a row or two away from the Kirk family in the courtroom gallery.
