盖伊·巴特库斯(Guy Bartkus)是5月17日发生在加利福尼亚州棕榈泉生育中心外的致命汽车爆炸案的唯一嫌疑人，他似乎运营了多个社交媒体账户，在那里他发布了自制爆炸装置的视频和指向他计划的消息。
一位熟悉调查的消息人士告诉ABC新闻，执法人员正在审查这些账户，据信这些账户是由巴特库斯操作的。
一个名为“起诉进化”的YouTube频道的快照在该频道被撤下平台之前被保存到了在线档案中。
档案中包含了至少六年前的视频，显示了人们对自制炸药和化学物质的兴趣。
几个视频显示了似乎是自制爆炸装置的测试。
其他视频显示了对放射性材料的兴趣，标题如“盖革计数器旁边的铀矿”和“钍矿的钍石”。
当被问及“起诉进化”账户时，YouTube的一名发言人说，“我们终止了与嫌疑人相关的频道。”
该频道自周日起不再播出。
该发言人补充说，这些账户因违反平台关于暴力极端主义的政策而被删除。
其中一段来自YouTube账户的视频于5月12日被分享到一个有争议的专门讨论自杀的留言板上。据熟悉调查的消息人士透露，分享YouTube视频的账户使用了执法部门认为属于巴特库斯的同一用户名。
5月5日，该账户上的一篇帖子提到了一次失败的自杀企图，涉及毒品和自制爆炸装置。
周四，该账户再次发布，详细描述了令人不安的一氧化碳中毒死亡计划。在随后的一篇帖子中，该用户提到了“一些我可能不应该说的额外戏剧哈哈。”
据负责美国联邦调查局洛杉矶办事处的助理主任Akil Davis说，周日下午，犯罪嫌疑人被确定为25岁的盖伊·爱德华·巴特库斯(Guy Edward Bartkus)，他住在距离棕榈泉约50英里的Twentynine Palms。
戴维斯说，巴特库斯被认为是被发现死在被引爆的汽车旁边的人。
爆炸附近的生育诊所棕榈泉美国生殖中心(American Reproductive Centers of Palm Springs)在一份声明中表示，其工作人员以及卵子、胚胎和生殖材料在爆炸中没有受到伤害。
Palm Springs bombing suspect appears to have posted bomb tests on YouTube
Guy Bartkus -- the lone suspect in a fatal car bombing that took place outside of a fertility center in Palm Springs, California, on May 17 -- appears to have operated multiple social media accounts where he posted videos of homemade explosive devices and messages pointing to his plans.
Law enforcement officers are reviewing the accounts, which are believed to have been operated by Bartkus, a source familiar with the investigation told ABC News.
A snapshot of a YouTube channel, titled "Indict Evolution," was saved to an online archive before the channel was taken off the platform.
The archive contains videos dating back at least six years and pointing to an interest in experimenting with homemade explosives and chemicals.
Several videos show what appear to be tests of homemade explosive devices.
Other videos suggested an interest in radioactive materials, with titles like "Uranium ore next to Geiger counter" and "Thorite from thorium mine."
A spokesperson for YouTube, when asked about the account "Indict Evolution," said, "We terminated channels associated with the suspect."
The channel was no longer available as of Sunday.
The spokesperson added that the accounts had been removed for violating the platform's policy on violent extremism.
One of the videos from the YouTube account was shared on May 12 to a controversial message board dedicated to suicide. The account that shared the YouTube video there went by the same username that law enforcement believes belonged to Bartkus, according to a source familiar with the investigation.
On May 5, a post on that account mentioned a failed suicide attempt involving drugs and a homemade explosive device.
On Thursday, that account posted again, detailing disturbing plans for a death by carbon monoxide poisoning. In a follow-up post, the user referred to "some extra drama that I probably shouldn't say haha."
The suspect was identified on Sunday afternoon as 25-year-old Guy Edward Bartkus of Twentynine Palms, which is located about 50 miles from Palm Springs, according to Akil Davis, assistant director in charge of the FBI's Los Angeles Field Office.
Bartkus is believed to be the person found dead next to the detonated vehicle, Davis said.
The fertility clinic near the blast, the American Reproductive Centers of Palm Springs, said in a statement that its staff members, as well as eggs, embryos and reproductive materials, were unharmed in the blast.
