Whilst digging around the internet looking for information, I came across an intriguing timeline. I believe this poster is from here also, and this timeline has probably been shared before, but I found it interesting. I have condensed some of it, and clarified, for myself, other portions. It can be found in its entirety here

Routier Crime Timeline
Author: JonGalt 4/12/02
0151: Darlie stabs Damon in her first attack. During this attack, she stabs herself in her own right arm. She stabs Damon with wound one and two.
0155: Darlie stabs Devon who has woken up during his brother's attack. He is stabbed the first time, stabber's face to his front. Wound #1 is the first one delivered. Wound #2 is delivered as Devon is face up on the carpet, most likely dying, with the attacker at his head, mostly likely on the knees, stabbing downward and across the torso. NOTE: This is the only wound in which the stabbing is reversed. It is also delivered prior to his actual death.
0156: Devon is dead.
0157: Darlie paces and thinks how to handle the situation. She paces from Devon to the front door. She decided to 'clean up' what evidence she can. She goes to the kitchen.
0205: Darlie begins wetting towels to wash areas of the couch and sink. The towels are half dry, and half wet ... the dry part being used to wipe away any leftover water smears. She leaves the towels in various areas of the living room as she realizes she continues to bleed and cannot clean more than flat surfaces.
0210: Darlie sits on the trunk by the front door, removes the socks and puts on Darin's high top sneakers. She sprints out the front door and drops the sock 75 yards away and returns to the house where she slips out of the laced up sneakers.
0212: She enters the kitchen and rinses the knife and tries to cut her own throat, but stops due to the pain. She rinses out the sink basin. She only uses one side of the sink, as the baby bottle is still upright.
0222: Darlie tips the coffee table and deposits a fairly large amount of blood there. She grabs the bread knife.
0225: Darlie enters the utility room to get the towel she uses for her own wounds. She is dropping blood freely in the utility room.
0227: She holds/wraps towels to her wounds as she cuts the garage screen and leaves a small amount of blood in the garage.
0230: She notices Damon has crawled from where she first stabbed him and is moving towards the door. (During this time he has tried to stand by using a glass top table leaving his print in Darlie's blood). She is winded and wounded, but she reaches him, lays down the knife in order to get a hold of him with both hands. She picks the knife up again and delivers hesitation wounds, one and two. She also delivers wound #4. She then switches hands and delivers wound #3.
0231: She lays down the knife on the counter & smashes wine glass. She calls 911. Darin comes downstairs.
0235: Officer enters home.
