As Virginia State Police continue to look for more clues in the disappearance of 20-year-old Virginia Tech student, Morgan Harrington, her parents, Dan and Gil Harrington, released a statement to the public.

On Wednesday, police reported the last known sighting of Morgan was on the Copeley Road Bridge, which leads to Ivy Road and is a heavily trafficked part of Charlottesville.

Police are asking for help from anyone who may have been driving or walking on the Copeley Road Bridge on the night of October 17. They say they have received several leads since releasing a detailed timeline of Morgan's movements outside the arena Wednesday.

Morgan's parents released the following statement Thursday.

We are doing everything in our power to bring Morgan home.

In the timeline police released Wednesday, Morgan was reportedly last seen at the Copeley Road Bridge about an hour after she was denied re-admittance the the Metallica concert at the John Paul Jones Arena.

State Police Lt. Joe Rader issued the new time line for the Morgan's disappearance at a news conference in Charlottesville.

Morgan’s Critical Hour:

8:30 p.m. - Outside John Paul Jones Arena
8:48 p.m. - Friend called Morgan's cell phone
9:00 p.m. - Seen in University Hall parking lot adjacent to JPJ
9:10 p.m. - Near Davenport Field RV Park and UVA Track
9:20 p.m. - On Copeley Bridge near intersection with Ivy Road

Rader says, "We know we don't have all the information there is in Charlottesville about this case."

He urges anyone who saw anything outside the Metallica concert between 8:30 p.m. and 9:30 p.m. to call police. Police are concentrating on what happened outside the arena.

Around 8:30 p.m., witnesses saw someone matching Morgan description at the ticket counter outside JPJ, trying to get back in the concert after she ended up outside.

At 8:48 p.m., a friend of Morgan's inside the arena called her on her cell phone asking if she was OK. Morgan apparently told her friend not to worry as she was going to get a ride from friends in Charlottesville.

Around 9 p.m., witnesses saw Morgan walking and carrying her black purse with backpack straps in the parking lot outside University Hall.

Ten minutes later, Morgan made her way to the RV parking area near the UVA track. On the night of the concert, that area would have been filled with RVs.

Witnesses saw Morgan there around 9:10 p.m., but they said they left about ten minutes later, leaving her in the parking area alone. The morning after the concert, a passerby found Morgan's purse on the ground.

The last known sighting of Morgan Harrington was on the Copeley Road bridge near Ivy Road at 9:30 p.m.

Police believe people driving or walking along the bridge must have seen Morgan after that time. They believe she may have gotten into a car.

"Perhaps you saw someone stop a vehicle to discuss something with this young lady. That would be important. Perhaps you saw this lady get into a vehicle. That would be important," says Rader.

The new time line explains why police spent so much time in the Copeley Road area looking for clues. Now, they're revealing where she was with the hope that someone will know where she is.

Morgan's parents did not appear the Wednesday news conference, but have said they believe she was taken by a stranger and that foul play was involved.

Police are asking any witnesses to come forward. They say every detail counts, and since the Copeley bridge is well traveled on Saturday nights, they hope to jog people's memories of the night of October 17.

People can submit tips anonymously by calling the Virginia State Police at 434-352-3467.

There is a $150,000 reward being offered for information that leads to finding Morgan.
