When triangulating Dennis Wayne Barfield's position, the sample locations were (1) 29°55'41.96"N 80°07'20.08"W, (2) 25°55'12.05"N 80°07'20.78"W, and (3) 25°55'26.23"N 80°09'07.23"W. These correspond to (1) a position out in the Atlantic Ocean well off the coast of St. Augustine (Jesse is shown near the water taking measurements on the hood of a car), (2) close to 15645 Collins Ave., Sunny Isles Beach, FL (Michael's position, verbally given as 324 N. Oakhurst, Hallandale, FL), and (3) Oleta State Park behind 16101 Biscayne Blvd., Aventura, FL (Fiona, location unspecified other than house number 124), and calculating 25°55'23.88"N 80°08'54.07"W for Dennis puts him deeper in Oleta State Park, close to 2500 NE 163rd St., North Miami Beach, FL, very close to Fiona's GPS position. The computer's map however has Fiona and Dennis near the NE corner of NW 8th Ave. and NW 43rd St., Miami, FL.
When Michael gets a call from "Dr Finley" he is able to hold his injured arm up to his ear to take the call. Later when he leaves Fi's house and is asked to raise his hands above his head he struggles to lift his arm.
