Hanover Police are investigating two separate deaths at the same apartment building on 7th Avenue, calling one of them suspicious.
Police were called to the building shortly after 6 p.m. Saturday and found a deceased female inside one of the units.
The teen is being identified as 16-year-old Claudia Weppler. Police say she was a temporary resident of the apartment.
Police say her death is suspicious, but they have no indication violence was involved.
A post mortem exam is scheduled Monday at the London Health Sciences Centre.
Three hours later, officers were then called to another unit in the same building to reports of a second death. Police found a 47-year-old man dead in his apartment.
Investigators say the deaths are not related.
The next of kin for the 47-year-old man has been notified. Police will not be releasing his name since his death was determined to be from natural causes.
