I'm in the process of building the timeline based on confirmed, sourced information. Still have a lot of info to add, but this is what I have thus far:
MACKENZIE COWELL TIMELINE
Confirmed Info Only - No Rumors
09 February 2010 (Tuesday):
3:01 PM - Mackenzie
leaves the Academy of Hair Design where she works, gets in her car, and drives away.
3:40 PM - Mackenzie's
phone data indicate that she is at/near the Riverfront Park boat ramp. While there, she sent a message to her boyfriend ("hey") and received a message from her boyfriend ("hey").
5:42 PM - A cell tower
bounces a signal off of MacKenzie's phone. This is the final activity on McKenzie's phone. Location has not been released by investigators.
8:02 PM - Residents
report to Rivercom finding a 1997 red Pontiac Grand Prix in Squilchuck area, 2395 Pitcher Canyon Road, parked near a cattle gate. LE uses the registration info on the car to
identify Reid Cowell as the owner, who confirms that his daughter has been out past curfew. One
set of foot prints led away from the locked car toward road asphalt. "Somebody got the car there and parked it
without anybody knowing about it.” Mackenzie's purse was inside the car, but her
cell phone, debit card with $20 on it, and gas card were missing. Initially, Washington State Crime Lab processed the car, but found no indication of anything unusual, and computers at both parents' residences were checked with
nothing unusual found. Later, local press says that
some evidence has been discovered in the car and sent to the State Crime Lab.

FBI profilers arrive late Saturday to assist with the investigation.

Mackenzie's mother, maternal grandfather, father, father's fiance, two brothers, and boyfriend attend the memorial. Noticeably absent is Mackenzie's mother's boyfriend.

For this one, we said, ‘Enough is enough. We want this valley to be a safe place.'"
