The only thing you can do is climb on the light on top of The Scream. This doesn't work very well but it is unavoidable, and the way the island is supposed to work.
At night, when you sneak back into the museum, that is your plan to catch the thief. It does not work.
Go back the museum : you have a package waiting for you.

Night
The mystery man on counterfeit island is the thief that stole the painting from the museum. That is the only reason why he knows the secret passage into the museum. Good Luck!!!! :) :)
night right after you get caught the thief is the investigator
You never see the thief when you get to the museum at night. While waiting, you hang on the lamp above the painting and set off the alarm. The police inspector arrests you and apparently thinks you're the bad guy.
The art thief is back on Counterfeit Island. As part of Counterfeit island, you don't need to do anything in Early Poptropica except get the key from the curator at the Pop Art Museum, then return to Counterfeit Island to open the Inspector's house.

The theft was caught on the museum's security cameras. To help search them, you need the timecard from the museum guard. He is at the Clown Store. In the museum Security Room, play the video from that night and you can get a photo of the thief. (It is the shady guy who suggested that you guard the painting. You were set up.)
