留痕（2019）

既然是淡水而非咸水
Given this was freshwater, not salt,
我推算死后间隔时间为5至12个月
I'd put PMI at five to 12 months.
而包裹的头则是截然不同的情况
Now the wrapped head is something completely different.
包裹提供近乎完美的保护 使其不被掠食
The wrapping has provided near perfect protection from predation.
这里有别的东西
There's something else here.
被斩成两半的蛇
A snake cut clean in half.
这附近应该不多见
Can't be many of those around.
今年想不想取代我在
Fancy taking my place on the
反恐指挥部和 鉴识爆破实验室的顾问一职
SO-15 and FEL advisory meet this year?
天啊 那件事会让你被记住一辈子
Oh my God, you will never live that down.
我满手是汗 根本没办法按简报笔按钮
My hands were so sweaty, I couldn't press the power point clicker.
我去开
I'll go.
我是波顿唐鉴识爆破实验室的芬恩
I'm Finn. From the Forensic Explosives Laboratory at Porton Down.
麦金文总督察
DCI McKinven.
抱歉 我们只是在… - 尼尔和芬恩 认识一下
Sorry, we're just... - Neil, Finn, Finn, Neil.
是自♥制♥的水桶炸♥弹♥
It's a bucket bomb. Homemade device,
跟用于帕森绿地站攻击未遂案的类似
similar to that used in the failed Parsons Green attack.
混合了面粉
A combination of flour
和双氧水作为燃料 形成这种面团状
and hydrogen peroxide is the fuel, creating this dough-like mixture.
接着将TATP装入管中
TATP is then placed in a tube
再插入面团
and thrust in to the dough.
加上手♥机♥振动组件和电池
Plus a vibrating phone component and battery,
代表可以用一般电♥话♥引爆
which means the device can be called up from a standard phone.
手♥机♥的振动器触发爆轰反应
The vibration in the phone triggers the detonation.
使炸♥弹♥客能够离开现场 从远处引爆
Which makes it possible for the bomber to leave the scene and detonate from afar.
那为何没爆♥炸♥
So why didn't it go off?
TATP引爆器
TATP. The detonator.
燃烧而非爆♥炸♥ 这是一种不安定的化合物
It burnt rather than exploded. It's an unstable chemical.
很多地方会出问题
A lot can go wrong.
TATP近年来被用在许多攻击事件
TATP has been used in many attacks in recent years.
包含与伊♥斯♥兰♥端主义有关的爆裂物
Including in devices linked to Islamic extremism.
这不是伊♥斯♥兰♥端主义
This isn't Islamic extremism. - Sure?
你确定能排除吗
Can you rule it out?
我们可以提供暂时确认的过氧化物品牌
We can provide a tentative identification of peroxide brands.
售出双氧水就是种警示
Sales of hydrogen peroxide can trigger red flags
商家必须通报异常的购买♥♥模式
and vendors have to report odd purchasing patterns.
还有一件事 我不是手♥机♥专家
One other thing. I'm, I'm not a phone expert
但这看来像诺基亚
but to me this looks like a Nokia.
廉价易取得、匿名、没有应用程序或相机
Cheap, available, anonymous, no apps, no camera.
或许能取得序号♥ 查出手♥机♥的身分
We could maybe get a serial number off this and ID the phone.
多谢 这件事我可以请爱丝拉帮忙
Thanks. Well, I can get Azra to help me with that.
口袋里装满石头
A pocket full of rocks.
增加额外重量
That's your extra weight.
不只是吸满水 检查另一个口袋
Not just waterlogged. Check the other pocket.
都是石头
Full of 'em.
DNA数据库中有人跟那颗包裹的头吻合
Okay, we've got a match on the DNA database for the wrapped head.
一具有蛇的刺青、被斩首的男性尸体
A decapitated male body with a snake tattoo
11个月前在康瓦尔郡 潘道尔灯塔附近的海滩上被发现
was found 11 months ago, on a beach near Pendower Lighthouse in Cornwall.
天啊 - 他们会把身体的断层扫描结果传来
Wow! - They're sending through the CT scan of the body.
应该是保存良好 或许还被冷冻
Well, then. It's well-preserved. Frozen perhaps.
其他尸块呢
What about our other remains? - Nothing yet.
还没有发现
Nothing yet.
你是怎么认识他的
How do you know him?
那个菲尔 - 是芬恩
Phil? - Finn?
认识好多年了 曾一起进行研究计划
Known him for years. We've worked on research projects together.
这样啊
Right.
他来了就代表我能继续参与本案
Him being here makes it possible for me to stay on the case.
我知道
I know.
你平安我就放心了
I'm glad you're safe.
凯蒂听到你的声音 她说感觉很慌张
Kitty heard your voice. She said it sounded wobbly.
说慌张也没错 - 我没事
Wobbly's right. - I'm okay.
那就好
Good.
这里光天化日的
We are in broad daylight.
我不是在耍你
I'm not playing games with you.
不要耍我
No games.
爱丝拉
Azra.
你在哪里
Where are you?
丹食外送员的事查出眉目了
I've got something on Dundeats Riders.
来查看新的炸♥弹♥
Just looking at the new bomb.
请你回来
I need you back here.
你一定会很高兴
You're gonna love this.
了不起 爱丝拉
Impressive, Azra.
不好意思 - 终于到了
Sorry, everyone. - Finally.
是被关在高机密实验室吗
Were you locked up in a high security lab?
好 我们已查出结果
Right. We have results.
有三家美食外送公♥司♥在丹地营运
Three food delivery companies operating in Dundee.
丹食、嚼车、好食送
Dundeats, Chowcart and Deliverdish.
总共有450名外送员
Four hundred and fifty delivery riders in total.
我已向外送公♥司♥取得 所有外送员的姓名与用户名称
I've obtained names and usernames for all riders from the delivery companies.
接着由此找出
From there I searched and recovered images
所有未被你们查访到的外送员照片
for all riders you didn't interview.
都是透过平常的社群媒体
Usual social media routes,
不过有些是来自大学部落格
but some were from university blogs,
有些出自通讯软件“信♥号♥♥” 音乐串流平台用户照片
some from Signal, Spotify profile pictures,
“我的健身伙伴” 亚马逊购物清单等等
uh, MyFitnessPal, Amazon Wishlist, whatever.
所有人在网络上都有照片 即使自以为没有
Everyone's got a photograph online, even when they think they don't.
现在大家会发现有些外送员是绿点
Now, you will notice that some of the riders are a green dot.
代表他们在三家公♥司♥都有接单
Well, they work for all three companies.
有些是蓝点
Some are a blue dot.
帮两家接单
And they work for two companies.
不过以红点显示的31名外送员
But 31 riders, the red dots,
他们只替一家公♥司♥接单
they just work for one company.
值得注意的是那些只替一家接单的
Interestingly, those who only work for only one company,
都是丹食外送员
only work for Dundeats.
没有人只在嚼车或好食送接单
No one just works for Chowcart or Deliverdish?
没错
Precisely.
来 由你按
Here go on. You can click it.
这有可能不代表什么
Now it could be random.
然而我心想
But, I thought,
“为何会这样 这些外送员是谁
why would that be? Who are these riders?
丹食有何独特之处 ” - 我们见过其中几个
What is it about Dundeats? - We've met some of these guys.
那就回去找 他们在哪里 是什么人
So go back to them. Where are they? Who are they?
是受到甘莫夫妇的控制吗
Are the Gemmells controlling them?
爱丝拉 真的很厉害
Azra. This is incredible.
在这31名外送员之中
Of the 31 riders,
其中17人被我用L标注
I've marked 17 with an L.
这些人在爆♥炸♥案当晚都曾上线
All the Ls were logged on on the nights of the bombings.
炸♥弹♥客不可能上线 这样做太笨
The bomber wouldn't log on. That'd be the dumbest thing he could do.
也可能是最精明的
Or the cleverest.
也可能纯粹是在接单
Or they were just working?
有些人整天跑
Some work all hours.
也可能只是很忠心 就喜欢帮丹食接单
Or maybe they're just loyal. They like working for Dundeats.
又或许丹食是最老的公♥司♥ 资安措施最马虎
Or maybe Dundeats is the oldest company and has the most lax security.
全国所有外送公♥司♥
All delivery companies, nationally,
都正在为安全协议进行升级
are in the process of upgrading their security protocol.
部分的系统已经改善
Now, some systems have improved,
可是有些外送员加入的时间
but there are those riders who signed up
早于这些系统的安装
before those systems were in place.
所以在新的公♥司♥ 有“代班”这类的行为就会被抓
So in a new company, you can't get away with subbing for instance.
“代班”
Subbing?
也就是当外送员出借自己的登录数据
It's when a rider loans out their log-in details.
该外送员或许并非本人
The named rider might not be the actual rider.
那要怎么确定这些丹食外送员真是本人
So how do we know if any of these Dundeats riders are who they say there are?
无法确定
We don't. - So, all this...
这么多… - 抱歉打扰了
Sorry to interrupt.
我刚从薇乐莉甘莫以前教书的学校回来
Just got back from the school where Valerie Gemmell used to teach.
但她在学校不是叫做甘莫老师
Only she's not known there as Mrs Gemmell.
而是卡拉纳老师
She's known as Mrs Callanach.
她保留前夫的姓氏 继续教小朋友
Kept her ex-husband's name. Continuity with the kids.
姓什么 - 卡拉纳
Mrs what? - Callanach.
