第三个证人，告诉肖万不要跪在弗洛伊德身上，作证
周一，检方传唤唐纳德·威廉姆斯(Donald Williams)作为第三名证人。在一段目击者视频中，可以听到唐纳德·威廉姆斯(Donald Williams)在与弗洛伊德(Floyd)的遭遇中批评明尼阿波利斯警方。
他作证说，威廉姆斯正从杯装食品店的拐角处走过，这时他听到一阵骚动，看到弗洛伊德在地上，肖万跪在他身上。
威廉姆斯说，当威廉姆斯到达那里时，弗洛伊德“以一种痛苦的方式说话”，向官员们发出声音，说他很痛苦，他想要他的妈妈。
“他的呼吸变得非常沉重，”威廉姆斯说，并补充说，很明显，他正在努力喘息。

威廉姆斯说，弗洛伊德的眼睛“慢慢滚到后脑勺”，鼻子开始流血，不久他就“没有生命了”。
威廉姆斯说，他作为一名拳手的经历让他相信，肖万在弗洛伊德脖子上的位置将弗洛伊德置于迫在眉睫的危险之中。

国防部试图证明911调度员不是使用武力政策的专家
在一次交叉询问中，辩护律师埃里克·纳尔逊(Eric Nelson)让911调度员耶拿(Jena)匆匆浏览了这次遭遇的时间表，并向她强调了她对明尼阿波利斯警方使用武力政策的了解。
纳尔逊似乎想让陪审团知道，疾走不熟悉警方如何处理此类事件。
匆匆承认，在她担任调度员的七年里，她只在调度中心的监视器上看到过三到四次警察事件的现场直播。
Derek Chauvin trial: Witnesses questioned by lawyers
The trial for Derek Chauvin, the former Minneapolis police officer charged in the death of George Floyd, began Monday in Minneapolis.
He faces charges of manslaughter, second-degree murder and third-degree murder.
The trial is expected to last four weeks.
3rd witness, who told Chauvin to stop kneeling on Floyd, testifies
Donald Williams, the professional mixed martial arts fighter who can be heard in a witness video criticizing Minneapolis police officers during their encounter with Floyd, was called by the prosecution as its third witness Monday.
Williams was walking around the corner from the Cup Foods when he heard a commotion and saw Floyd on the ground with Chauvin kneeling over him, he testified.
Floyd "was speaking in a distressed way" when Williams got there, vocalizing to the officers that he was in pain and that he wanted his mom, Williams said.
"His breathing was getting tremendously heavy," Williams said, adding that it was apparent that he was struggling to gasp for air.
At one point, Floyd's eyes then "slowly rolled to the back of his head" and his nose started bleeding, and soon after he was "lifeless," Williams said.
Williams said his experience as a fighter led him to believe that Chauvin's position on Floyd's neck was putting Floyd in imminent danger.
Another witness on the scene who is a paramedic told the officers multiple times to check Floyd's pulse, but no one did, Williams said.
Prosecution calls 2nd witness, employee of store across the street from Cup Foods
Alisha Oyler, a shift manager for the Speedway located across the street from Cup Foods, first noticed police officers “messing with someone” when she began watching the encounter involving Floyd, she told prosecutors Monday.
Oyler took seven separate video recordings on her cellphone but could not immediately recall details, stating that it had "been so long."
Defense tries to establish that 911 dispatcher was not an expert on use of force policies
During a cross-examination, defense attorney Eric Nelson walked 911 dispatcher Jena Scurry through the timeline of the encounter and pressed her on her knowledge of Minneapolis Police use of force policies.
Nelson seemed to want the jury to know that Scurry was not familiar with how police handled such incidents.
Scurry acknowledged that she has only seen police incidents play out live on monitors in the dispatch center three to four times in the seven years she has been a dispatcher.
