Authorities have released new video footage of the last known sighting of the Georgia mom whose body was found naked and burned at the bottom of a ravine.
The Habersham County Sheriff’s Office said in a news release that on September 10, 59-year-old Debbie Collier was captured by a security camera at a Family Dollar in Clayton, in North Georgia. While at the store, she purchased a tarp, a torch lighter, a rain poncho, and a reusable tote bag, per NBC News.
The mother appeared to be "calm and not afraid of anything" as she made the purchases around 2:55PM, the release said, stating that investigators saw what she bought from a receipt provided by the store.
Authorities also disclosed that the store was approximately 13 miles north of the wooded area off State Road 15, where the mother's body was found at 12:44PM on September 11.
Watch the security footage below:In the video, the real estate office manager was wearing a red sun visor, a Herschel Walker shirt, a blue skirt, and what appeared to be black boots.
The sheriff's office revealed that they obtained the footage after they got a lead that Collier's daughter, Amanda Bearden, was seen at the shop that day. However, the video shows that it was in fact Collier herself.
In addition to this, Authorities also confirmed that Collier supposedly left the store at 3:09PM, after verifying the purchases she made by getting a copy of the receipt.
"In the video, the victim appears to be calm and not in fear of anything," police said, per Daily Mail. "All video footage obtained from the store and surrounding businesses reflect that the victim was alone in the van at the time she visited the store."
The police's mention of the "van" is a reference to the black Chrysler Pacifica Collier rented from Enterprise because her own car was reportedly in a repair shop.
The vehicle was located the next day at the entrance to a wooded area off close to Tallulah Falls - 60 miles north of where the mom lived in Athens with her husband Steve, 67.
"This information allows investigators to narrow the time of death to a window beginning at 3:09 p.m. on Saturday, September 10 to the discovery of the body on Sunday, September 11 at 12:44PM," said the sheriff’s department, per Daily Mail.
The baffling horrific death has taken a new twist as Collier’s 15-minute visit to the store was right before her daughter said that she received a mysterious message along with a $2,385 Venmo payment.
The worrying message read: "They are not going to let me go, love you there is a key to the house in the blue flower pot by the door."
According to NBC News, Habersham Chief Deputy Murray Kogod said in an email that there was no other physical or eyewitness evidence suggesting that Collier was abducted.
"We will, of course, continue to review all possible theories as we move forward and obtain further information," Kogod said, per the outlet.
The sheriff's office has noted that it had found no evidence linking the mother's death to suicide. The manner and cause of death still remain unclear as the state crime lab was conducting an autopsy.
On September 11, Collier’s van was found on the side of a state road in Clarkesville. Authorities scanned the numbers of her license plate and discovered the vehicle was connected to a person reported missing in the area.
K-9 units brought to the scene led investigators to her body and she was found lying on her back, naked and holding a small tree with her right hand.
In addition to this, the mother was severely burned in her abdomen, according to the Habersham County Sheriff’s Office’s report.
After her body was found, Collier's daughter told CBS 46: "Somebody took my whole world from me," adding: "She was a beautiful, kind, giving woman - and she didn’t deserve any of this…I want justice for my mom."
