Just double checked.
The first list she was looking at was Dade County Baot Registrations.
Only showed 4 names I could see, Kevin Bovender, Samantha Bowdry, and Hugo Bowerman and Lee Bowers.
Then she randomly hops over to a list of employees. A few have check marks by thier names, Lee Bowers (Robery Detective) on the list, but check mark just above his name, not by it. Then she scrolls down to Dexter's name with a check mark.
I'm assuming she's trying to piece together Lundy's files. Saw Lee Bowers name on the DMV list, and then hopped over to the employee list trying to figure out what all the employees with checks by thier names have in common. She got down to Dexter's name, who she knows has a boat, and stopped because she realized that was evidently not the connection since Bowers also had a boat, but didn't have a check.
Could be totally wrong, but just my observations based on the information given.
