据当局消息，南佛罗里达大学的两名博士生已失踪。这两名学生均来自孟加拉国，其家人和朋友表示，自上周四起便无法与他们取得联系。
南佛罗里达大学警察局在一份新闻稿中表示，27岁的扎米尔·利蒙和纳希达·布里斯特最后一次被人看到是在4月16日的坦帕地区。正在同步参与调查的希尔斯伯勒县警长办公室在给CBS新闻的声明中表示，侦探们正在积极追查线索，并在希尔斯伯勒县和皮尼拉斯县等多个地点开展搜寻工作。
利蒙的家人透露，他的研究方向是人工智能在环境科学中的应用，原本计划于本周提交博士论文。南佛罗里达大学警察局称，他最后一次被看到是在上周四上午9点左右，地点是他在坦帕的住所。布里斯特的研究方向是化学工程，当局表示，她最后一次被看到也是在4月16日，大约是上午10点，地点是南佛罗里达大学坦帕校区。
亲友们表示，两人的失踪不符合他们平时的行事风格，十分担心他们的安危。

“这对我们来说极其蹊跷，”利蒙的兄长祖贝尔·艾哈迈德说道，“两个人怎么会……凭空消失？”
据艾哈迈德透露，由于即将提交论文，利蒙曾嘱咐家人不要随便联系他。
“他当时特别忙，4月14日周二那天他还跟我们说，除非是紧急情况，否则不要打电话找我，”艾哈迈德告诉CBS新闻。当局表示，自4月16日周四以来，尚未确认有人与利蒙取得过进一步联系。
两名学生的一名朋友告诉CBS新闻，利蒙曾在实验室的共享Outlook日历上标注，他和布里斯特失踪当天计划居家办公。
“他申请了居家办公来修改论文，”这位名叫奥默·侯赛因的朋友说道，“他把这件事记在了Outlook日历里。”
侯赛因表示，两人属于同一个朋友圈，此前朋友们都不知道他们可能正在交往。
艾哈迈德称，两人渐生情愫，“他们慢慢萌生了共度未来的想法，但都优先考虑学业”。
布里斯特的兄长扎希德·普兰托告诉CBS新闻，布里斯特通常每天都会和家人联系。
“我们没有一天不和她联系的，”普兰托说道，“我们全家都崩溃了。”
据两家人透露，此次失踪也不合常理，因为两人已经订好了暑假返回孟加拉国的机票。

2 University of South Florida doctoral students have gone missing, authorities say

Two doctoral students at the University of South Florida have gone missing, according to authorities. Family and friends of the pair, both from Bangladesh, say they haven’t heard from them since last Thursday.
Zamil Limon and Nahida Bristy, both 27, were last seen in the Tampa area on April 16, the University of South Florida Police Department said in a news release. In a statement to CBS News, the Hillsborough County Sheriff’s Office, which is also investigating, said detectives are actively following leads and conducting searches in multiple locations, including Hillsborough and Pinellas counties.
Limon is studying the use of AI in environmental science and was set to present his doctoral thesis this week, his family said. He was last seen around 9 a.m. last Thursday at his residence in Tampa, the USFPD said. Bristy is studying chemical engineering. She was also last seen on April 16, at approximately 10:00 a.m. on the USF Tampa campus, authorities said.
Loved ones say their disappearances are out of character and are concerned for their well-being.

“It’s extremely suspicious for us,” said Zubaer Ahmed, Limon’s brother. “How can two people… disappear out of nowhere?”
According to Ahmed, Limon had asked family members not to contact him because of his upcoming thesis presentation.
“He was extremely busy, and Tuesday [April 14]…he also informed us that, please don’t call me unless it is… [an] emergency,” Ahmed told CBS News. There has been no further contact with Limon confirmed since Thursday, April 16, authorities said.
A friend of the pair told CBS News that Limon had put on a shared Outlook calendar at the lab that he was planning to work from home on the day he and Bristy went missing.
“He took a work-from-home to work on [his] thesis,” said Omer Hossain, the friend. “He put it in the Outlook calendar.”
Hossain said the pair were part of the same friend group, and that friends were unaware that the two may have had a romantic relationship.
Ahmed said the pair had developed feelings, “gradually they thought about having a future together, but they preferred their study first.”
Bristy’s older brother, Zahid Pranto, told CBS News that Bristy would typically be in touch with her family on a daily basis.
“There has been no single day without contact with her,” Pranto said. “My family is just devastated.”
According to the families, the disappearances also don’t make sense because the pair already had flights booked to travel to Bangladesh for summer break.
