The body of a male New Zealand college student went undiscovered in his room at a campus residence complex, possibly for weeks, according to local news reports.

The body was found Monday evening at a residence at the University of Canterbury in Christchurch, according to a statement from the Christchurch Police. Specialist police teams were called in to assist with the formal identification of the student, whose name has not yet been released.

The police said they were investigating how long the student’s body had been in the residence, but would not say how they were alerted or when they believe the student had died.

The local news outlet Stuff, citing unnamed sources, reported that the student’s body could have been there for nearly two months, and that fellow students had not known anything was wrong until they noticed a smell and alerted the authorities. Officials declined to comment on those reports.
