A man whose body was found at a recycling plant had only been in the UK a day before his death, it has emerged.
Canadian student Garrett Elsey, 22, was found dead at New Earth Solutions in Kings Weston Lane, Avonmouth, near Bristol, on Thursday morning.
Police carried out searches of nine locations across Bristol that were on a bin collection route earlier but narrowed their hunt to Jacobs Wells Road which was the only site still sealed off.
Mr Elsey's family told the Edmonton Journal newspaper in Canada that he arrived in the city to study for a master's degree in international security at Bristol University, having recently graduated from Ottawa's Carleton University with a degree in political science and history.
Mr Garrett arrived in Bristol on Wednesday, checked into his student residence and sent his parents a text message to say all was well.
His uncle, Brent Elsey, told the newspaper: "There are a lot of outstanding questions."
Police have witnesses and security tape but are still trying to piece together what happened, he said.
Mr Elsey said his nephew, from Sherwood Park, Alberta, would be remembered as an accomplished young man.
"The accolades are pouring in. He's done a lot of things in his short 22 years. He was hard working. When he set his mind to things, he was successful," he told the newspaper.
Friends of Mr Elsey have paid tribute on Facebook.
Jess Cassidy wrote: "When I was told that Garrett Elsey had passed away, I was utterly shocked and didn't believe it. Being 22-years-old, he had his entire life ahead of him, and he was extremely bright and determined.
"Garrett was one of the nicest people I've met, and one of those people that just makes the experience of school and life so much better.
"Garrett, you touched so many souls without realizing how much of a gift you had given others. You will truly be missed. RIP."
An Avon and Somerset Police spokesman said on Friday: "Although formal identification is still to take place, we believe we know the identity of the body, a man in his 20s, and his family have been informed.
"The investigation continues to piece together how the body came to be in the bin and we are keeping an open mind at this stage."
