Terri Briggs
The CageTerri Briggs is one of the Briggs twins whose eager online exchange with a man posing as a young admirer leads them to plan a secret meeting in Newcastle. The messages show her acting alongside Berri Briggs at each step: sharing the excitement, weighing what to send, and preparing to leave home. When their mother finds both beds empty, that coordinated plan becomes a disappearance, and later police evidence identifies the exchange as grooming by Jason Dodds.
Identity and school life
At school, Terri and Berri are familiar figures in detention. Their teacher, Miss Thompson, names them together and notes that they have been there before. Asked why they are being kept behind, Terri answers that they were talking in class; Berri specifies that it happened in Mr Jansen’s lesson. The small exchange establishes a shared pattern of classroom mischief, with Terri speaking first and her sister adding detail rather than leaving her to answer alone.
The twins’ plans also sit against the routines of family and school. The day before their intended meeting, they run out of school to buy clothes for their adventure. Their excitement is already being fed by messages from the men they expect to meet. They travel into town by bus and spend the journey bent over the smartphone, talking in excited whispers. The planned outing is not an isolated thought: it has begun to shape their time, their attention, and what they expect to do the next day.
Messages and growing expectations
A smartphone is central to the twins’ contact with the person they know as Mario. At McDonald’s, they settle at a corner table and bring it out again. Terri leans her head close to Berri’s shoulder as they check for a reply, a physical closeness that mirrors their shared involvement in the conversation. When a message arrives, Berri identifies the sender as Mario. He asks whether they are still willing to do what they had discussed before, and the twins look at one another and giggle before Berri replies cautiously that they might be.
The exchange then turns toward photographs. Mario invokes the phone the men supposedly bought for the girls and asks for a new picture. Berri proposes that he send one first; after looking to Terri and receiving her nod, she sends the request. His reply instead praises the girls and says he would rather receive a picture of them. This sequence shows the pressure moving through a shared conversation: Berri types, but Terri is present as a participant whose assent helps determine what they do next.
The contact continues after the twins prepare for bed. Having each taken a long bath and washed their hair, they crouch over the phone together. The sender demands confirmation that the arrangement is definite and warns against being messed about. Berri answers that they are coming. The insistence and reassurance make the meeting feel settled, even as the messages supply no reliable basis for the girls to know who is really contacting them.
A further message directs them to take the Metro to Newcastle and meet opposite Newcastle Central Station at around ten. The twins set an alarm for half past six so they can leave before Linda Briggs usually gets up, around half past seven. Terri says she is too excited to sleep. Her remark captures the emotional force of the plan: anticipation has displaced rest and is already guiding a deliberate departure from the household’s ordinary morning routine.
Disappearance and the investigation
The following morning, Linda Briggs goes upstairs intending to wake her daughters and get them ready for school. She has prepared their breakfast, but when she opens the bedroom door she finds both twin beds empty. Their being unmade is ordinary; the absence of both girls is not. Linda stops in disbelief. The scene supplies the sharp reversal promised by the secret plan: what the twins had treated as an exciting journey out of the house is first encountered by their mother as the simultaneous disappearance of her daughters.
The later examination of the phone gives investigators a name behind the messages. Maddie tells Jane Bowman that the number belongs to Jason Dodds, although the girls called him Mario. She describes evidence that he groomed them, pretended to be someone he was not, pestered them for photographs, and persuaded them to skip school and meet him in Newcastle. The investigation establishes that the twins sent topless pictures, while also noting that they had stayed together and that he had not persuaded them to do more than take their tops off. The distinction matters: the record identifies both the exploitation and the limits the sisters maintained within it.
In a separate interview, Frank McQuillan describes how he and others presented themselves as only a little older than the girls, created a Facebook page, and used photographs of attractive young men found online. His account helps expose the fabrication behind the attractive identities the twins believed they were approaching. Read alongside the phone evidence about Jason Dodds, it places their messages within a wider method of deception, rather than a genuine exchange with the young men represented in the images.
The twins’ shared role
Terri’s part in the available scenes is inseparable from Berri’s, but she is not merely background to her sister’s actions. She offers the initial explanation for their detention, travels with her sister to prepare for the meeting, participates in the message exchanges, and voices her own excitement about leaving early. In the online conversation, Berri often enters the replies, while Terri’s presence beside her helps make the decisions collective. The investigation later emphasizes that the sisters stuck together under pressure, a form of mutual support that also explains why the grooming scheme is best understood as a sequence they entered together.
That solidarity does not make the danger less real. The girls’ agreement to go, their preparation, and their secret early departure show how an online deception acquired practical force: messages became photographs, a named meeting place, an alarm, and two empty beds. The evidence presented here establishes their disappearance and the grooming that preceded it, but does not itself disclose what ultimately happens to Terri. Within these scenes, her defining position is the tension between shared confidence with her twin and an adult-made deception that converts their trust and anticipation into risk.
