A Bangladeshi doctoral student at the University of South Florida was found dead in Florida while another Bangladeshi student remains missing, reports AP.

Police said that the victim’s roommate had been taken into custody on multiple charges.

Hillsborough county sheriff Chad Chronister said the remains of Zamil Limon were discovered on Friday morning on the Howard Frankland Bridge spanning Tampa Bay.

Nahida Sultana Bristy, a Bangladeshi PhD student, is still missing, and search efforts are ongoing.

However, Bristy’s family claimed that she also died. Her brother made the claim through a post on social media, although authorities are yet to officially confirm her death.

‘Our sister is no longer with us. Inna lillahi wa inna ilaihi raji’un,’ her brother Zahid Hasan Pranto said in a Facebook post on Saturday.

Police have taken Limon’s roommate, Hisham Saleh Abugharbeih, into custody on preliminary charges including domestic violence, false imprisonment, tampering with evidence, failing to report a death, and unlawfully moving a body.

According to officials, deputies initially responded to a domestic violence call at a residence about a mile from the campus.

Officers managed to safely evacuate the suspect’s family members before he barricaded himself inside the house and refused to surrender.

A SWAT team was later deployed, and the suspect eventually exited the residence peacefully.

Authorities said he initially communicated with law enforcement but later stopped responding.

Limon and Bristy, who were in a relationship, had been missing since April 16.

Limon, a student of geography, environmental science and policy, was last seen at his apartment, while Bristy, a chemical engineering student, was last spotted about an hour later at a campus science facility.

University police were alerted after a family friend reported being unable to reach either of them last Friday.
