Witnesses with information about the last movements of Co Antrim teenager Shona Gillan have come forward following an appeal by her distraught family.
The 18-year-old had disappeared after leaving her mother's home in Valiant Court in Antrim on Wednesday, March 3.
Her body was found by a dog walker on the Saturday morning in a one-foot deep stretch of the Six Mile Water.
After an appeal by Shona's family in the Belfast Telegraph earlier this month, witnesses contacted police with information that could help piece together what happened to the teenager prior to her disappearance.
Shona's sister and brother, Amy and Ryan Reid, had made an emotional appeal for information after a number of issues around her death that had deeply concerned the family.
On the Monday after Shona was found, the family was told a post-mortem examination would take place in the morning and that she would be returned home to be waked by 4pm.
As they waited for her body to be returned they got a call from the undertaker shortly before 4pm saying the PSNI had told him to return the remains immediately for further examination.
However, the teenager's remains had already been embalmed, ruling out a second post-mortem. When her body was finally returned to the family they noticed marks on her face and scratches on her knuckles.
During a meeting with the coroner's office on Wednesday, Amy says they were informed that witnesses had come forward and given information to police.
"The coroner contacted me personally and said that everything was being done, they asked for three months to allow the investigation to take place, my solicitor said they don't usually contact people so early on and so we were really grateful for that. The coroner said that there has been people coming forward to police since the story was carried. As a family we just want to thank anyone who has come forward and urge anyone else with information to please do the same," she said.
On the night of her disappearance Shona - the youngest of nine children - had gone to meet friends.
Her phone was last used at 11.40pm on the Wednesday, and after that police say there was no other activity from her number.
After her body was discovered Amy was called to the riverside to identify her sister's body, which was in the back of a morgue van.
Amy said: "They warned me she was still wet. Her fake eyelashes were still attached, one was sitting on her cheek, but she didn't look as though she'd been in the water for any length of time."
"Where she was found, the water is really shallow. It's a popular place with walkers. I can't understand, if she'd been there since Wednesday night or Thursday morning, how she wouldn't have been found sooner.
"There are questions about how she got to the river. It would be less than 15 minutes' walk away from where we think she was last seen. I find it difficult to believe that she would have walked there alone in the dark.
"Shona was scared of the dark, and I mean terrified. She wouldn't even go to the toilet if the light was off. She would never have walked alone at night," Amy added.
PSNI Inspector Julian Buchanan said: "This is obviously a deeply upsetting and distressing time for Shona's family and loved ones, and I am appealing for anyone who saw or spoke to Shona in recent days, or who can provide information to police, to please call us on 101, quoting reference 1122 06/03/21."
