Some timeline:
Jan 27, Monday, 10:15 am. TS and Gannon get into the red truck.
Monday 10:15-2:15, TS and Gannon are driving around the greater CS area, as far north as Castle Rock, exchanging exercise equipment for hockey equipment and looking at a bike for Albert. She got lost at one point. No mention of food stops. Gannon has some kind of electronic device with him.
Monday, 3:15 pm TS says she's exercising in the basement and that Gannon goes to an (unknown) friend's house. This is about the time that Gannon's sister would be coming home from school. Gannon does not take his phone.
Monday, 4:38 - TS says her daughter, HH, comes home.
Monday, 6:30ish, TS contacts AS about Gannon not being home, TS checks Gannon's phone and finds a Google search regarding whether parents can track an iPhone, concludes that he is a runaway, which is what she tells LE. LE does not mention the exact time of the call in its initial statements. Initially, LE states he was "last seen" between 3:15 and 4:00.
Monday evening: Some searching is done in Lorson Ranch.
Monday, around 7 pm: LE enters Gannon database into Missing Children's and Person's databases
Jan 28, Tuesday.
6:50 am approximate. TS leaves home to drive 100 miles north to DIA.
8:50 am TS rents a small Kia from Budget at DIA. She picks up Albert, who is flying in from Oklahoma. It is unclear exactly when his flight landed. TS drives AS, in the KIA, to CS to search "door to door" for Gannon.LE reports that officers and detectives are searching for Gannon "in between" other calls for service.
Late in the day (approximate) LH arrives from SC. Unclear who picks her up or which airport. She spends the night "talking to LE."
10:00 pm. LE is observed in the backyard of the Stauch home, searching with flashlights. One car is visible in the driveway.
At some point on Tuesday, AS speaks to MSM (KOAA) and says that Gannon left around 3:30. An earlier, unsourced MSM statement says that Gannon went to a friend's house "a few streets away." AS mentions the streetlight rule and how he texted all of Gannon's friends, none had seen him.
National Guard is involved in search. Weather turns colder, there is snow falling on Tuesday night in the region.
Jan. 29, Wednesday
11:00 am, approximate. TS leaves CS with the rental car to drive 100 miles to return the Kia.
1:20 pm. TS returns the Kia, receipt shows over 900 miles driven. No confirmation if this is correct. If correct, then 200 of those miles were conveying AS to CS and then taking the car back, leaving about 750 miles unaccounted for.
LH's aunt, Veronica Birkenstock, contacts LE to organize an "official search." Search is still focused in Lorson Ranch.
Evening: A vigil for Gannon, held in Lorson Ranch. 200 people have searched Lorson Ranch for 2 days. Drones and other tech is involved. They used a 10 mile radius. Homeless encampments were searched.
Jan 30, Thursday
LE is observed watching the Stauch house for "an extended period of time" in two cars. When two men and a woman emerge and get into "a truck" and leave, LE also leaves.
FBI gets involved. LE says they have "Persons of interest." LE does not name them.
School district tells the Gazette that Gannon was absent on Monday. One neighbor reveals he's been using a drone to search a 50 mile radius. Vacant houses are searched, LE contacts trash removal and landfill operators but does not search landfills at this time.
Jan. 31, Friday
LH makes another plea to help find Gannon, asking "Why is this happening to him?" Gannon's status is changed to "missing, endangered."
Friday, 2:40 pm. TS gives her first video interview, standing with her back to the camera at the edge of housing developments in Lorson Ranch. This is the interview where she mentions she had to leave the Mandan house without belongings, so she and daughter go to Marshall's to "buy underwear" where they are met by police. TS claims her civil rights were violated during an interrogation, that LE demanded car keys from her daughter, that daughter resisted giving keys, and was placed in the back of a police cruiser (apparently, at Marshall's parking lot).
TS reveals she is no longer at the family home. Perhaps she left on Thursday? Her location was widely shared on SM, but I do not think MSM shared it.
------------------
That Friday interview marked the beginning of what now looks like an active PR campaign by TS. She has been super active on social media for those few days (4 days after Gannon goes missing).
