During a press conference Wednesday morning, Virginia State Police released a detailed timeline of events and places where Morgan Harrington may have been seen October 17.

Lt. Joe Rader says, "We know we do not have all the information...that will help resolve this case."

Rader says between 8:20 p.m. and 8:30 p.m., witnesses saw someone matching Harrington's description at several locations outside the John Paul Jones arena.

Rader says from 8:30 p.m. to 8:48 p.m., a person matching Harrington's description was seen outside the arena.

At 8:48 p.m., Harrington had a phone conversation with a friend telling them she was outside the arena. Harrington told her friends she would try to get a ride ride home from friends in Charlottesville.

From 8:48 p.m. to 9 p.m., Rader says more witnesses saw Harrington outside the arena. He says there is no credible information saying she reentered the arena.

From 9 p.m. to 9:10 p.m., Rader says someone appearing to be Harrington, who was carrying a black purse, was walking through the University Hall area. He says no one can confirm whether or not she was with someone.

He adds someone matching Harrington's description was confirmed to be in the Lannigan Field parking area between 9:10 p.m. and 9:20 p.m.

Rader says, at about 9:20 p.m., the witnesses who identified her left the area. He says there is no information that Harrington left with any of those witnesses.

From 9:20 p.m. to 9:30 p.m., Rader says witnesses saw someone appearing to be Harrington on a nearby bridge. Rader says this is the last confirmed sighting.

"Somewhere out there lies...the vital line that we need," says Rader.
