The signage on the store robbed in 2009 says "Collins Jewellers" but this story is supposedly taking place in Indiana, so the store should use the American spelling (as is later seen in news articles), i.e. "Collins Jewelers." (The actual store used for filming is in the Vancouver B.C. area.)
The address for Maryanne's house that Derrick sees on an envelope and the address that Jennifer gives to Frank for the same house do not match. Also, the envelope address states the house is in Greenville, Indiana, but shows a zip code for Garrett, Indiana, which is 260 miles north of Greenville.
Jennifer is seen driving along Mary Ave., then she stops across the street from a grocery store and sees the man she suspects of killing the storage facility owner. She then turns left to follow the man, who has backed out of his parking space onto Mary Ave. and turned right. There's no way Jennifer could have traveled along Mary Ave., stopped to see the man, then turn left and still be on Mary Ave.
When Jennifer finds the money, she says its from Costa Rica and from Belgium. In Belgium we use euros since 2002, just as they do in France, Germany, Austria, The Netherlands ... You can't tell just by seeing the notes that the money is from Belgium or is going to be used there.
The woman posing as a fiancée during the 2009 jewelry store robbery states she wants an engagement ring like Kate Middleton's. However, Kate and William did not announce their engagement until November of 2010.
When Detective Lynwood opens the storage locker, containing the body, the head and shoulders of a film crew member, although out of focus, can be seen on the right hand side coming between the camera and the opening roller door.
