Macon police say they've obtained video of Lauren Giddings on June 25, the day she was apparently last seen alive.
That's according to Police Chief Mike Burns, who spoke to the media Friday morning at 1058 Georgia Ave., Giddings' home.
Burns would not say when the video was taken or where.
Her family told 13WMAZ's Lauren DiSpirito Thursday that Giddings visited friends on June 25 and used her phone and email until around 10:30 p.m.
Burns said he hoped to have results of FBI forensic tests of evidence "the first of the week."
He visited Giddings' home Friday after a volunteer K-9 search team from Dooly County searched around the Barrister Hall apartment complex.
Burns said the search dogs "didn't have any hits on any new places around here."
"We haven't found any new evidence at this time."
He said the dogs searched Giddings' apartment and the surrounding complex.
Burns said at mid-morning that investigators have expanded the search area.
Later in the day, police said they searched Rose Hill Cemetery, the area along the Ocmulgee River and railroad tracks alongside it, and Baconsfield Park, areas where Lauren jogged regularly. There was no word if investigators found any evidence.
He said police have gotten numerous email tips from college students and tips from other agencies. "We've been checking everything," he said.
Burns said he returned to the scene to talk with Giddings' father Bill and answer any questions he had. Bill Giddings returned to the apartment to continue removing his daughter's belongings.
Police say her body was found next to the apartment building a week ago Thursday, on June 30. They say she was a homicide victim and they so far have no suspects.
Burns said Friday "we still have several people of interest that we've got to eliminate or either prove they were involved."
He said Giddings' neighbor Stephen McDaniel remains a person of interest. Burns said McDaniel's apartment was not searched again Friday.
Asked about the progress of the investigation more than a week after the discovery of Giddings' body, Burns said "we're still interviewing people today (Friday) and that might lead to more interviews.
Asked if thought this was a random attack or by someone who knew the victim, Burns replied, "I'm not going to say."
He urged the public to take normal precautions: walk in pairs at night and try to park under a light in parking lots and look around for anything suspicious before opening the car door.
