UPDATED 4:47 p.m.

The chief of Charlottesville police is asking land owners near the Downtown Mall to search their property for traces of missing University of Virginia student Hannah Graham. Chief Timothy J. Longo made the plea at a press conference downtown and asked that anyone who may have seen her to contact a tip line set up and manned by the FBI. Police showed surveillance video taken from McGrady’s Irish Pub at the corner of 10th Street Northwest and Preston Avenue as well as video from the Preston Avenue Shell gas station that showed a disoriented Graham first walking and later running down Preston Avenue. Longo said eyewitnesses saw her cross onto the Downtown Mall from Market Street. “If you have property, please inspect it,” Longo asked. “I hope people who may have seen her on the Downtown Mall hear the frustration in my voice when I say please contact us and let us know what you saw.” Longo said police contacted local merchants who have surveillance equipment and asked them to hold the tapes so that they could be reviewed for images of Graham. He noted that there are no city surveillance cameras on the Downtown Mall, something which Longo said he has long sought from the City Council. According to Longo, Graham had dinner Friday night with friends on the Corner and then left around 11 p.m. to go to another location. She is seen on video walking west on Preston Avenue, stopping at McGrady’s outdoor eating section and then walking down Grady Avenue. She reappears on the video and walks east on Preston. A few minutes later a video at the Shell station captures her running east on Preston Avenue toward downtown. There are no other people in the video. “There is a location at the railroad bridge and Preston Avenue where people do tend to congregate,” Longo said. “Perhaps she was uncomfortable as she walked by.” Longo said the search for Graham will continue, focusing downtown and east of the mall.

UPDATED at 12 p.m. ... Police are expanding their search for missing University of Virginia student Hannah Graham onto the Downtown Mall and beyond after video cameras caught pictures of her running down Preston Avenue and onto the mall.

Police have reported that a video from cameras at the Preston Avenue Shell gasoline station show Graham running down the street. She was alone in the video. Another video camera caught her going onto the Downtown Mall.

Police are reportedly searching areas downtown including areas near the railroad tracks and areas near Garrett Street.

While police continue their search, UVa President Teresa A. Sullivan issued a statement recommending that UVa parents keep in contact with their students and encourage students to seek counseling, if need be.

"If your son or daughter seems to be in distress, do not hesitate to refer them to professional counseling if you believe it would be helpful for them. UVa's Counseling and Psychological Services (CAPS) department has trained clinicians who can help students manage anxiety or other emotions they may be feeling," Sullivan wrote today.

"You are perhaps the most important resource for your student. Many students will seek advice and reassurance from their families," Sullivan wrote. "If you become concerned about your student's resilience or health, please let me, Vice President Pat Lampkin, or [UVa Dean of Students Allen Groves] know of your concerns."

Sullivan sent a similar message yesterday to staff and faculty.

"We are encouraging our students to maintain their daily schedules. Having structure in their day will help them in coping with uncertainty, and I hope that those of you who teach and support our students will help them stay on track," she wrote. "If students come to you in distress, I know that you will be understanding and listen to them carefully, but you should also not hesitate to refer them to professional counseling if you believe it would be helpful for them."

The search for a University of Virginia student shifted Tuesday after police obtained video showing her walking outside a Charlottesville bar, but authorities appeared to draw no closer to finding her three days after her disappear ance.

As the FBI, state Department of Emergency Management and search dog teams joined the effort to find second-year student Hannah Elizabeth Graham, 18, a familiar mystery gripped Central Virginia, where a string of young women have gone missing over the past five years, starting with Morgan Harrington in 2009. Search teams combed the area near McGrady’s Irish Pub on Grady Avenue, where video from a camera perched atop the bar showed Graham, wearing a bare-midriff mesh crop top and black pants, walking east at 12:46 a.m. Saturday toward Preston Avenue, police said in a news release. The area is less than a mile from 14th and Wertland streets, where Graham said in a text to friends at 1:20 a.m. that she had gotten lost while walking home from a party. Friends last saw Graham, of Fairfax County, about 11:50 p.m. Friday near Camden Plaza, an off-Grounds apartment complex, according to Facebook posts. Graham later was seen leaving a party near 14th Street about 12:15 a.m. Saturday, Charlottesville police said. Authorities said there were indications Graham was intoxicated that night. Friends and family reported her missing Sunday after not hearing from her for an uncharacteristically long time, police said. Investigators began looking for her that day near The Corner. Graham is seen in the video interacting with someone briefly outside the bar, then walking east, alone, police said. A state police helicopter flew over Charlottesville on Tuesday evening, tracing Graham’s known movements Friday night and Saturday morning. Police set up a tip line at (434) 295-3851, along with a command post at the Albemarle County Police Department. Tips have flooded in, police said. “We’ve gotten probably about 60 calls in relation to the case, and every little bit helps,” said city police spokesman Lt. Ronnie Roberts. “You may think it’s not important, but if you have any information — any at all — please call.” Graham’s family released a statement Tuesday through UVa expressing heartbreak and saying they also had been “heartened by the outpouring of support and help” they’ve received. “We remain hopeful that Hannah can be found soon,” the statement said. The statement also said Graham “would not disappear without contacting family and friends.” “She is highly responsible and organized,” the statement said. “She embraces life with energy and enthusiasm and has enriched the lives of many.” The family is in Charlottesville, police said. Friends and relatives have taken to social media to aid the search. A Facebook page, “Help Save Hannah Graham,” had gathered nearly 4,000 likes as of Tuesday night, and Twitter posts with the hashtag #HannahGraham began circulating. UVa President Teresa A. Sullivan released a statement Monday afternoon, saying officials are both concerned and cooperating fully. “The members of the University of Virginia community are united in our deep concern for a UVa student who is missing and has not been in touch with her family or friends since early Saturday morning,” Sullivan said. Graham is the third area woman to go missing this summer. Janet Renee Field, 49, of Palmyra, was reported missing July 3. Her vehicle was found 20 miles from her home at the Zion Crossroads park-and-ride lot. Less than two weeks later, Bonnie Santiago, 56, of Albemarle County, was reported missing after leaving her boyfriend’s home on Carter Mountain. Neither has been found. Before this summer came a string of cases involving young women, starting with Harrington, 20, the Virginia Tech student who disappeared outside the John Paul Jones Arena during a Metallica concert in October 2009. Her remains were discovered on an Albemarle farm three months later. No suspects have been named in that case. Two 19-year-olds — Orange County’s Samantha Ann Clarke in September 2010 and Charlottesville’s DaShad “Sage” Smith in November 2012 — since have vanished. No suspects have been charged in their disappearances. In the spring, a jury convicted Randy Allen Taylor in the killing of Alexis Murphy, 17, a Nelson County High School student who went missing in August 2013. She never has been found. Roberts said police do not believe there’s a connection between Graham’s case and the others. Help Save The Next Girl, an organization founded by Harrington’s mother, Gil, has added Graham to the organization’s map of unsolved missing persons and murder cases involving women in Virginia over the past five years. Authorities describe Graham as white, 5 feet, 11 inches tall, with a slender build, light brown hair, blue eyes and freckles. ------------------------------------------------------------------------------------------- The family of missing University of Virginia student Hannah Graham is both heartbroken at her disappearance while "heartened by the outpouring of support and help we have received," they said in a statement released this afternoon. Family members said they "remain hopeful that Hannah will be found soon" and urged "anyone with any information, however insignificant it may seem," to contact a dedicated tip line at 434-295-3851. "Those of us who know and love Hannah know that she would not disappear without contacting family or friends. She is highly responsible and organized. She embraces life with energy and enthusiasm and has enriched the lives of many," the family's statement said. "Her empathy is evident in her daily interactions with us and her friends." Family members said Graham loves UVa. "All summer she was looking forward to the start of the new school year. UVa is her intellectual home, a place that stimulates her thinking on a broad variety of topics. Socially, she has found kinship and passion with her fellow members of the ski team," the statement said. “We express our sincere gratitude to law enforcement and everyone who is involved in the search for Hannah. We also thank the university for the full attention they are devoting to the situation. The kindness and support of so many – her friends at UVa, particularly her friends on the ski team, her friends from high school, our neighbors, and the larger community – mean so much to us at this difficult time."

Police are adjusting their search for missing UVa student Hannah Elizabeth Graham after receiving new information about her whereabouts early Saturday morning. A new report from police said that Graham was last seen out front of McGrady’s Irish Pub on Grady Avenue at 12:40 a.m. on the Saturday that she went missing. Accordingly, police are now searching the area east of the bar and restaurant along Preston Avenue. This information comes out just hours after city police said they have received more than 60 tips about Graham’s whereabouts. This has been a breaking news update.

As law enforcement continues to comb the area where Graham was last seen, police are asking the community to phone in any information that may lead to the missing 18-year-old.

“We’ve gotten probably about 60 calls in relation to the case, and every little bit helps,” said Charlottesville police spokesman Lt. Ronnie Roberts. “You may think it’s not important, but if you have any information – any at all – please call.”

Graham, of Fairfax County, was last seen by her friends at the off-Grounds housing complex Camden Plaza about 11:50 p.m. Friday. Police said the last contact she had with friends was a text message sent at 1:20 a.m. Saturday saying she was lost in the area of 14th and Wertland streets.

The search effort widened as more time passed after police learned Sunday of her disappearance, Roberts said. The Albemarle County Sheriff’s Office, Virginia State Police, UVa police and Charlottesville Police Department all are participating in the search.

“We may call in additional agencies today,” Roberts said, but did not elaborate.

The search has expanded from the area of 14th Street Northwest and Wertland Street down to Cherry Avenue, Roberts said.

“Investigators have been in touch with her family,” Roberts said. “We are all hoping for the best.”

Police describe Graham as white and 5 feet, 11 inches tall with a slender build. She has blue eyes, light-brown hair and freckles. Surveillance footage captured three hours before she went missing shows Graham dressed in black slacks and a gold and black, bare-midriff top with mesh cutouts.

Anyone with information about Graham is asked to call Charlottesville police at 970-3280 or Crimestoppers at 977-4000.
