Interesting, Dr. Wilkinson isn't very chatty.

Victim? Yes he knew her, she was his patient.
Maxamine? No, I'm a GP not an oncologist. (where was the "Dammit Spock!" :) )
Own truck? L160, month old.
Anyone else have keys? Two sets. My wife has one set. Other set is missing.
Where's the truck? Garage at home. Took firewood to ranch.
Where were you? Grocery shopping with wife. She's at home, go talk to her.

Are your legs getting tired yet? Yup, it's off to a new location.
