Here is the best timeline I have been able to piece together so far:
- Thurs., May 4, 11:30 am: Sheila leaves her family's Schaumburg home to visit friends in Bloomingdale (it is an approx. 15 to 20 minute drive from Schaumburg to Bloomingdale with the latter being straight south of the former). She is seen by her father, who was the second to last to leave home that day (the last being Sheila).
- Thurs. - Early Fri., May 5, Exact Time Unknown: After hanging out with friends for the day, Sheila gets a call from friends in Bradley -approx. a ten-minute-drive to the SE from Bourbonnais- asking her to come and stay with them.
- Fri., May 5, 12 am to 1 am: Sheila is physically seen for the last time at a friend's house in Bloomingdale.
*During the press conference, a reporter starts to ask what Sheila might have been doing or where she might have been between leaving Schaumburg and arriving in Bloomingdale, as well as while in Bloomingdale, and the family attorney says those details cannot be discussed at this time.*
- Fri., May 5, approx. 1:50 am: Sheila sends a text to tell friends she had made it to the toll plaza where Interstate 57 intersects Interstate 294.
*After that, all communication ceases. According to Bourbonnais Police Chief James Phelps, Sheila's cell phone last pinged on a tower near Bourbonnais and Momence (I have not been able to find the exact time of the ping, other than the 1:50 am text being the last communication).*
- Fri., May 5, approx. 2 am: Sheila's car's I-PASS is used for the last time, exiting the I-294 tollway onto Route 57 toward Bourbonnais (the same location as the toll plaza referenced above).
*At the beginning of the conference, the attorney says they have not been able to determine if it was actually Sheila who was driving the car at that point.*
*Sheila never made it to her friend's in Bradley. "Her friends in Bradley waited for her until 5 a.m. while growing increasingly worried," [family friend and attorney Thomas Glasgow] said.*
