The death of rough sleepers in Oxford is a "national tragedy....playing out on our streets", according to a city councillor.
Four deaths in the last two months have prompted the council to launch an investigation into common factors linking them.
Councillor Linda Smith said the council was "saddened and concerned".
Oxford West and Abingdon MP Layla Moran said she was "shocked and ashamed", calling it a "national scandal".
491 rough sleepers died in the UK in 2017, according to the Office for National Statistics.
In the South East, there were 69 deaths identified as rough sleepers in 2017.
There's been an overall rise in the number of people rough sleeping in Oxford during that time, up from 19 to 61 in 2017.
But that number did fall slightly last year, dropping to 45.
Oxford City Council announced a £2 million project to tackle the issue in October.
The money went towards developing a Homeless Hub in the city, offering emergency accommodation and support to get people off the streets in the long term.
