Introduction
DinoFun World held a series of events about Scott Jones, an internationally renowned football star in last year. Scott was planned to appear in two stage shows each on Friday, Saturday, and Sunday to talk about his life and career, as well as a show of memorabilia in the park’s Pavilion (Area 32). However, the event was marred. Although the crimes were rapidly solved, they have intention to know to how to do better preparation in the future. The task is understanding how people move and communicate in the park, as well as how patterns changes and evolve over time, and what can be understood about motivations for changing patterns.
IDs that Stand Out for Their Large Volumes of Communication
The 2 IDs that stand out for their large volumes of communication are 1278894 and 839736, separately.
ID 1278894 sent and received messages at regular intervals for a period by observing the dots on blue lines are relatively sparse and the interval was fixed. It communicated with a large amount of visitors, but minority of visitors didn't respond. Based on this condition, it may be advertisements, service tips and others.
Hypothesis: According to official website of DinoFun World, ID 1278894 should be the Cindysaurus Trivia Game that is available from the app.
The ID 839736 communicates irregularly. Because dots on the orange line are close and form a line. It is continuous. In addition, every receivers gave feedback to it.
Hypothesis: ID 839736 should be a status check sensor. Security personnel check everyone's movement status by the feedback.

- Vandalism’s Time
Our main task is to identify the criminal offenders. So the first step is to filter data to narrow the range. If we want to filter data, we should identify time of the incident.
The times of communication with external increased sharply at 11:44 AM, Sunday. It also validated the crime occurred before around 11:30 AM of the 3rd day.
We know the crime scene was Creighton Pavilion (Attraction 32, Coordinate (32,33)). Through the timeline of checking in Pavilion, we could know it opened between 8:10 AM – 9:30 AM and closed between 9:31 AM – 11:29 AM on Sunday.
Hypothesis: The offender(s) checked in the Pavilion, and hided inside, then sabotaged during the closing time. When Pavilion opened again, he escaped with the opportunity that many visitors were entering. Meanwhile, people found the destructive activity and messages sent were up to the peak.
Based on the hypothesis, visitors who checked in between 8:10 AM and 9:30 AM on Sunday was extracted.
