Questions
GC.1 – Summarize and
describe the events of January, 2014 relating to the disappearance of the GAStech employees. Focus on the disappearance of the
employees, and the events immediately before and afterward. The summary should
include the following:
a.
Who: Individuals and groups involved and their
roles
b.
What: A description of what happened over the time
period
c.
Where: Associate events with locations
d.
When: Specific times of activities, particularly as
it relates to planning and execution
e.
Why: A description of the motives or motivations
of the individuals or groups involved
f.
How: What, if any, notable entities provided
support for or facilitated the events that took place? These could be people,
places, or things that helped those responsible for the disappearance in some
way.
Do not reproduce the overview or
MC1 materials concerning background knowledge, although you may reference this
information if needed. Visualizations illustrating how you determined the
summary points above are encouraged. Please limit your response to no more than
five images and 500 words.
Groups
and their motivations
There are two major (overlapping) groups in the Kronos
incidents: GAStech and POK. GAStech
extracts natural resources from Kronos to the detriment of the environment and
inhabitants’ health, while POK is a resistance movement that wants to change
this situation. Two GAStech sub-groups are of
interest. The first group consists of security personnel who have ties to known
POK members and Kronos civilians who have suffered from GAStech
practices: Osvaldo, Bodrogi, Ferro, I. Vann, and Minke Mies. The second group
consists of managers who are vital to GAStech
operations: Sten Sanjorge,
Vasco-pais, Barranco,
Strum, Campo-corrente, Dedos,
Bergen, and Ovan. Some of the managers have become
rich in a recent IPO of GAStech and do not originate
from Kronos, while the Kronos population have so far only suffered from GAStech operations. This is a motivation for POK to disrupt
GAStech.
Events
January 20, 2014
Morning GAStech
has an annual corporate meeting at its headquarters, which is interrupted due
to a (suspected) bomb threat and subsequent evacuation. Soon after, the Abila police is called to GAStech
for an unspecified emergency.
Afternoon GAStech-Tethys
confirm they are missing a number of employees, while unofficial reports
indicate a kidnapping.
Evening The police announces that there
are about 14 GAStech individuals missing, there is no
indication that the missing individuals have left the island.
January 21, 2014, Morning The number of missing people is
decreased to 10 during a police conference, and CEO Sten
Sanjorge is not among the missing. In addition, the
POK claim responsibility and demand a $20 million ransom from the CEO.
January 23, 2014, Evening POK stages a rally at Abila Park, led by
Silvia Marek. There is a heavy police presence but the rally progresses
peacefully. Later in the evening a fire is reported at the Dancing Dolphin
apartments to the northeast of Abila Park, which are
home to two GAStech managers: Bergen,
and Ovan.
The
fire is hard to control by firemen and at the end of the evening part of the
complex collapses after an explosion. Soon after the start of the fire a black
van is sighted south of the Dancing Dolphin at Brew’ve
Been Served. Quickly afterwards the van is chased by the police, due to
reckless driving. The chase comes to an end at Gelato Galore in the center of Abila, where the van is cornered by police. A standoff
ensues, where the front occupants (one man, one woman) reveal that they have
hostages (reported to be two women) who appear to have been in the van for a
longer period. Shots are fired by the hostage takers and a police officer is
wounded. The hostage takers surrender after being surrounded by SWAT.
The POK rally distracted police
from their usual duties, creating room for the drivers of the van (and likely
instigators of the Dancing Dolphin fire) to fulfill (or derail) their mission.
GC.2
– Describe at a high level the most significant networks that exist,
and how they have influenced each other to produce the current situation.
Please limit your response to no more than three images and 100 words.
We have information about two GAStech
networks: its organization into departments and the social contacts of its employees.
The departments were known in advance, while social contacts have been inferred
from matching credit card transactions, emails, and GPS positions (which
includes shared living spaces of employees, see figure below). In addition
there is the POK social network that extends into GAStech.
These networks influence each other:
·
GAStech
departments divide social contacts between employees, creating cliques within
departments but fewer inter-department contacts.
·
GAStech
departments and POK contacts created a pocket of POK affiliates in the GAStech security department.
GC.3 – Identify
three of the most significant information gaps that remain at the end of the
time period covered by the data. Describe why this missing information would be
important to the investigation. Highlight in your visualizations where these
knowledge gaps are present. Please limit your response to no more than three
images and 250 words.
Dancing Dolphin fire and the black van
incidents
The streaming data contains a
significant gap in relevant messages between the start of the fire at the
Dancing Dolphin and black van sightings. We expect these events to be related,
e.g., the fire and explosion could have been instigated by the drivers of the
van. However, we have limited and unreliable data to back this up.
POK network
Most of the POK ties with GAStech employees are inferred by matching surnames, which
make them unreliable and incomplete. For example, Edvard
Vann is probably not connected to POK even though his surname suggests
otherwise. Access to birth records from the Kronos government would provide
reliable family ties. Moreover, little is known about the internal POK
organization and its reach, while a network could be derived from government
records: law (fines, arrests, and permits), marriages, education (schools and
classes), military service (units), and municipality registrations (home
addresses).
Communication meta-data
Email subjects that originate from GAStech have been provided but offer only a glimpse of
employees’ day-to-day communications. Access to Kronos-wide telephone meta-data
would enable us to infer network activity of GAStech
and POK. It should also provide a more accurate image of social contacts in
comparison to the credit card and GPS data.
GC.4 – The police have sufficient manpower to investigate up to two
different locations simultaneously. Provide your best recommendation to the
police chief as to where the police should be deployed, and why. Provide visualizations that help describe the
importance of this action. Please limit your response to no more than two
images and 100 words.
Based
on the patterns in the GPS data from MC2 5 locations of interest have been
identified besides the home of the suspected kidnappers. Four locations are
most likely used to hold the abductees (A,B,C,D).
Since the home and three of the locations (C,D,E) were on the most likely route
of the black van that was carrying two of the abductors and two of the
abductees when they were apprehended, we suspect the remaining abductees to be
held at the remaining two locations (A,B). The coordinates of these locations
are (36.0807, 24.8469) and (36.0695, 24.8415).
