Maggie reads the name from the fake ID as Shauna McLaughlin. The ID is a Pennsylvania driver license that was clearly lifted from their website, as the name on it is Evelyn T. Sample, the date of birth is 04/25/1974, and the number is 99 999 999. This matches the sample driver license on the state's website as of the release date. This ID would indicate Maggie was 43 years old.
