If you were a cop, would this be worth persuing?

An apartment manager unexpectedly gets the keys returned in her drop box from a resident the day after Bin Laden has been killed.
The resident said he was a pharmacist from India. Trying to get a forwarding address, the manager calls his employer and finds he hasn’t worked there for 8 months.
Looking at the apartment the manager finds abandoned property which includes evidence of money transfers from Pakistan, black hair dye, and books to learn Spanish quickly. He has also left computer equipment and a flash drive.
Curious, the manager googles his old address and finds hits about a school famous for producing hackers and false ID’s.
She also discovers that he was never licensed as a pharmacist.
She also finds pills strewn all over the apartment and strange holes drilled in the ceiling.
When the police officer arrives he says that he sees nothing suspicious.
Is he off his rocker or is the manager and owner of the property paranoid?
