一名22岁的嫌疑人因涉嫌大规模枪击案警方称，周一在伊利诺伊州芝加哥郊区高地公园举行的独立日游行中。

据官员称，枪击事件造成6人死亡，约24人受重伤。

警方表示，经过一个小时的追捕，他们在周一晚上的一次车辆追逐中逮捕了罗伯特“鲍比”克里默三世。

警方说，枪手似乎是从一个屋顶开枪的，那里发现了一把大威力步枪。

警方称这次枪击事件是“随机的暴力行为”

在警方发布了一张Crimo和他的汽车的照片后不久，警官们说，北芝加哥警察部队在一辆与他们正在寻找的汽车相匹配的汽车中发现了相关人员。

当局说，在一次交通拦截后，司机逃跑了，并带领警察进行了短暂的追捕。据警方称，他在伊利诺伊州森林湖的美国41号高速公路和Westleigh路被拦下，并在那里投降。

送货司机瑞安·勒曼(Ryan Lerman)就在十字路口附近，拍下了逮捕过程。他告诉芝加哥美国广播公司WLS站，他立即从警察公告中认出了这辆车。

“他立刻被警察包围了，”他告诉电视台。"他们从公路的两边围了过来。"

视频显示，持枪警察走近汽车，命令司机下车。有人看见司机举起双手。

“最后他跪下，被警察逮捕，”勒曼说。“这太不真实了，我不知道我看到了什么。”

逮捕结束了疯狂的一天，这一天始于社区的大游行。

当局称，枪击事件发生时，游行已经进行了四分之三。狂欢者惊恐地逃离，留下空的婴儿车、翻倒的椅子和吃了一半的三明治。

莱克县副警长克里斯托弗·科维利在新闻发布会上说，警察向枪声跑去，但枪手已经逃跑了。

莱克县验尸官珍妮弗·巴内克说，五人——都是成年人——当场死亡，第六名受害者在医院死亡。

一名受害者已经被家属确认为78岁的尼古拉斯·托莱多。他的家人告诉ABC新闻，托莱多在20世纪80年代从墨西哥莫雷洛斯搬到美国。

据墨西哥外交部称，死者中还有一名墨西哥国民。

北岸大学卫生系统称共有31名患者;大多数人受了枪伤，少数人在混乱中受伤。高地公园消防队长乔·施拉格说，至少有一名儿童伤势严重。

当枪声响起时，参加游行的佐伊·尼科尔·帕尔查克抓住她的父亲，开始穿过人山人海。

“我看到许多人被屠杀，”她告诉ABC新闻。

“大家都在哭。我们最后躲在一个角落里，藏在一个垃圾箱后面。这名男子带着他的两个非常小的孩子在那里，为了安全起见，他把他们放进了垃圾箱，”她说。

Pawelczak说这个男人想离开去找他的另一个儿子，并让她看着垃圾箱里的两个孩子。

“所以我帮他照看孩子，”她说。“他们会问，‘发生了什么事?’我说，‘这只是烟火，没事的’，只是想让他们冷静下来。"

枪声响起时，大卫·鲍姆医生正在观看他的孙子、女儿和女婿在游行队伍中行进。

“尸体被可怕、可怕、可怕地伤害，你知道，是为战争而不是为游行制造的枪支和子弹，”鲍姆谈到一些受害者时说。

“护理人员迅速前往并评估了损失——看到了被炸得四分五裂的尸体，并迅速在他们身上盖上了毯子。然后继续努力帮助其他人，”他告诉ABC新闻。"这些是任何人都不应该看到的伤害。"

众议员布拉德·施耐德，伊利诺伊州。参加游行的他在推特上说，他承诺“尽我所能让我们的孩子、我们的城镇、我们的国家变得更安全。适可而止!”

警方要求任何参加游行的人查看他们的视频，并与当局分享。

据一名执法人员称，酒精、烟草、火器和爆炸物管理局在现场有特工，正在对收回的枪支进行紧急追踪。

埃文斯顿警方表示，枪击事件发生后，邻近的埃文斯顿郊区取消了自己的7月4日游行。

乔·拜登总统在一份声明中说他“请求联邦执法部门协助紧急搜寻枪手”

拜登说:“社区成员应该听从当地领导人的指导，我将密切关注我们对那些丧生者的更多了解，并为那些受重伤住院的人祈祷。”。

他指出，他最近签署了最重要的法律枪支管制立法几十年后，他补充说，“但还有更多工作要做，我不会放弃打击枪支暴力的流行。”

副总统卡玛拉·哈里斯在一份声明中说，“在一个应该与家人和朋友庆祝的日子里，我们哀悼在另一场无谓的枪支暴力中丧生的人。”

她说:“我们国家应该采取更多措施来解决枪支暴力问题。”。“拜登总统最近签署了近30年来第一项重要的两党枪支改革立法，我们将继续努力结束这种毫无意义的暴力。”

伊利诺伊州州长JB Pritzker在一份充满激情的声明中说:“没有任何语言可以形容那种等待并向一群带着孩子的家庭开火的怪物，这些家庭正在与他们的社区庆祝节日。这种邪恶剥夺了我们邻居的希望、梦想和未来，无法用语言来描述。”

这位州长写道:“单靠祈祷不会结束我们国家猖獗的枪支暴力恐怖。”“我们必须——也将会——终结这场枪支暴力的瘟疫。”

枪支改革小组的代表为我们的生活前进由佛罗里达州帕克兰2018年高中大规模枪击事件的幸存者成立的，在一份声明中说，“就在三周前，年轻人在高地公园和全国各地的社区组织了一次为我们的生活而游行。”

“我们为高地公园可怕的生命损失，以及一把大威力步枪带来的大屠杀感到悲痛，”他们说。“我们希望那些被谋杀的人永远和平，我们将为活着的人拼命战斗。”

新泽西州州长菲尔·墨菲(Phil Murphy)是对该国最近的大规模枪击事件做出反应的领导人之一，他在推特上说:“即使是7月4日庆祝我们国家独立的游行也不能幸免于我们国家的枪支暴力流行病。明天，我将签署七项全面的常识性枪支安全法案，使之成为法律。我们不能等待。”

芝加哥白袜队宣布计划在周一晚上对阵明尼苏达双城队的比赛前举行默哀，并取消了赛后的烟花表演。

执法部门长期以来一直担心枪手从高处开枪，警方称这可以给他们带来战略优势。

最致命的例子是2017年拉斯维加斯大屠杀在此期间，枪手在曼德勒海湾酒店占据了一个靠窗的位置。59人在这场成为美国现代史上最致命的大规模枪击事件中丧生。

在拉斯维加斯大屠杀之后，全国各地的执法部门更加重视保护公共活动周围的高架位置，但警方也承认，保护所有这些位置是一项多么艰巨的任务。

Highland Park mass shooting live updates: 6 killed at 4th of July parade, person of interest apprehended

A 22-year-old person of interest has been apprehended in connection with amass shootingMonday at a Fourth of July parade in the Chicago suburb of Highland Park, Illinois, police said.

Six people were killed and about 24 others were seriously hurt in the shooting, according to officials.

Police said they apprehended Robert "Bobby" Crimo III following a vehicular pursuit Monday evening after an hours-long manhunt.

It appears the gunman fired from a roof where a high-powered rifle was recovered, police said.

Police are describing the shooting as a "random act of violence."

Shortly after the police released a photo of Crimo and his car, officers said a North Chicago police unit they spotted the person of interest in a vehicle matching the one they were looking for.

After a traffic stop, the driver fled and led police on a brief pursuit, authorities said. He was stopped at U.S. Highway 41 and Westleigh Road in Lake Forest, Illinois, where he surrendered, according to police.

Ryan Lerman, a delivery driver, was near the intersection and filmed the arrest as it took place. He told Chicago ABC station WLS that he immediately recognized the car from the police bulletins.

"Right away he was surrounded by the police," he told the station. "They came from either side of the highway to surround him."

The video showed armed officers approaching the car with their guns drawn and ordering the driver to get out. The driver was seen putting his hands in the air.

"It ended with him getting on his knees and getting arrested by cops," Lerman said. "It was surreal, I didn’t know what I was seeing."

The arrest capped a frantic day that began with a popular parade in the neighborhood.

The parade was about three-quarters of the way through when the shooting broke out, authorities said. Revelers fled in panic, leaving behind empty strollers, overturned chairs and half-eaten sandwiches.

Police ran toward the shots but the gunman had already fled, Lake County Sheriff Deputy Chief Christopher Covelli said at a news conference.

Five people -- all adults -- died at the scene and a sixth victim died at a hospital, said Lake County Coroner Jennifer Banek.

One victim has been identified by family members as 78-year-old Nicolas Toledo. His family told ABC News that Toledo moved to the U.S. from Morelos, Mexico, in the 1980s.

A Mexican national is also among the deceased, according to the Ministry of Foreign Affairs of Mexico.

The NorthShore University Health System said it has a total of 31 patients; most suffered gunshot wounds and a few were hurt in the chaos. At least one child is critically injured, Highland Park Fire Chief Joe Schrage said.

When the gunfire erupted, parade-goer Zoe Nicole Pawelczak grabbed her dad and started running through the sea of people.

"I saw multiple people slaughtered," she told ABC News.

"Everybody is crying. We ended up making it behind a corner and we hid behind a dumpster. This man was there with his two very young children and he had put them in the dumpster for safety," she said.

Pawelczak said the man wanted to leave to find his other son, and asked her to watch the two children in the dumpster.

"So I watched his kids for him," she said. "They were like, 'What's going on?' And I was like, 'It's just fireworks, it's OK,' just trying to keep them calm."

Dr. David Baum was watching his grandson, daughter and son-in-law march in the parade when the gunfire began.

"Bodies were horribly, horribly, horribly injured from, you know, guns and bullets that were made for war -- not for parades," Baum said of some of the victims.

"The paramedics went quickly and assessed the damages -- saw bodies that were blown apart and put a blanket over them quickly. And then went on to try and help other people," he told ABC News. “These are injuries that nobody should have to see."

Rep. Brad Schneider, D-Ill., who was at the parade, tweeted that he's committing himself "to do everything I can to make our children, our towns, our nation safer. Enough is enough!"

Police are asking anyone who was at the parade to review their videos and share them with authorities.

The Bureau of Alcohol, Tobacco, Firearms and Explosives has agents on scene and is conducting an urgent trace on the recovered gun, according to a law enforcement source.

The neighboring suburb of Evanston canceled its own Fourth of July parade in the wake of the shooting, Evanston police said.

President Joe Biden said in a statementthat he "surged Federal law enforcement to assist in the urgent search for the shooter."

"Members of the community should follow guidance from leadership on the ground, and I will monitor closely as we learn more about those whose lives have been lost and pray for those who are in the hospital with grievous injuries," Biden said.

He noted that he recently signed into law the most significantgun control legislationin decades, adding, "But there is much more work to do, and I'm not going to give up fighting the epidemic of gun violence."

Vice President Kamala Harris said in a statement, "On what should be a celebratory day with family and friends, we are grieving the lives that were taken in another act of senseless gun violence."

"More should be done to address gun violence in our country," she said. "President Biden recently signed into law the first major bipartisan gun reform legislation in almost 30 years -- and we will continue fighting to end this senseless violence."

In an impassioned statement Illinois Gov. JB Pritzker said, "There are no words for the kind of monster who lives in wait and fires into a crowd of families with children celebrating a holiday with their community. There are no words for the kind of evil that robs our neighbors of their hopes, their dreams, their futures."

"Prayers alone will not put a stop to the terror of rampant gun violence in our country," the governor wrote. "We must -- and we will -- end this plague of gun violence."

Representatives of the gun reform groupMarch For Our Lives, founded by survivors of the 2018 high school mass shooting in Parkland, Florida, said in a statement, "Just three weeks ago, young people organized a March For Our Lives in Highland Park, along with communities across the country."

"We are grieving for the horrific loss of life in Highland Park, and the carnage brought on by a high-powered rifle," they said. "We wish eternal peace for those who were murdered, and we will fight like hell for the living."

New Jersey Gov. Phil Murphy is among the leaders reacting to the nation's latest mass shooting, tweeting, "Not even a parade on the Fourth of July celebrating our nation’s independence is immune from our nation’s gun violence epidemic. Tomorrow, I will sign seven sweeping commonsense gun safety bills into law. We cannot wait."

Law enforcement has long been concerned about gunmen firing from elevated positions, which police say can give them a strategic advantage.

The deadliest example of that is the2017 Las Vegas massacre, during which the shooter took up a window position in the Mandalay Bay hotel. Fifty-nine people were killed in what became the deadliest mass shooting in modern U.S. history.

In the wake of the Vegas massacre, law enforcement around the country placed a greater emphasis on securing elevated locations surrounding public events, but police have acknowledged how daunting a task it is to secure all such positions.
