The vehicle - is that what recently prompted the new direction?
“The sketch released Monday was drawn on Feb. 17, 2017, a few days after the victims' bodies were found. The picture was based on the description of a person who
saw something that the person felt needed to be reported according to,the sketch artist.”
Delphi murders: Investigators have had newly released suspect sketch for 2 years
Just tossing out some thoughts -
What was it the witness
saw they felt needed to be reported?
No indication if the person associated to sketch #2 saw the killer on the trail system but they might’ve.
No indication that person knew the suspect was the driver of the parked car, but they might’ve.
Does LE know the ID of this vehicle?
Was the vehicle stolen or not ever registered?
Was satellite tracking involved?
Did it turn up somewhere burned, abandoned or turned in to a wreckers?
Was it traceable
Your car may be invading your privacy
Perhaps LE only recently was able to connect the driver of this vehicle to the witness who made the report?
So many questions.
