Transcript of 4N6 -- Exploring Forensic Science

4N6 -- A mobile, social app for forensic edutainment

Project Description and Goals:
Create a wireframe for the online social learning platform
Business Case:
To create a social mobile game experience that is pedagogical and standards aligned.
Key Business Requirements:
Design and develop up to 16 content topics and activities centered around the curriculum that provides some level of application to field work of Forensic Science
Project Objectives:
Tiles (up to 16) which include: function (inputs) with instructions, learning content, design, and economy/rewards; leader board, and social
Help students learn, use, apply, and substantiate evidence to help solve a criminal case as Forensic Science detectives through a forensic science case work study

The Problem:
synthesizing of Massive U, JJ Enterprises and Pearson
The Solution:
Develop and customize the current MU/JJ platform to offer an interface that is applicable to forensic science and meets national standards
The Project Scope:
16 interactive tiles with one tile fully developed
Review curriculum, overview backend tracking capabilities
The material provided will provide adequate background knowledge
Project Constraints:
3 week time limit; no SMEs available
Project Risks:
The absence of SMEs may result in incomplete, unrealistic, or erroneous information
Time & Costs:
3 weeks; cost deferred for this pro bono project

##: Chapter and Topic
A: Activity
F: Functionality
C: Content

Additionally, each tile will have:
1. An opportunity for help text (which decreases the amount of badges earned),
2. Links to optional additional resources (which generate extra badges if viewed), and
3. An option to share the resources (for extra badges).

This will be explained further in the demonstration tile to be developed

Fire has a tendency to move in an upward direction, and thus the probable origin will most likely be the lowest point showing the most intense characteristics of burning. At the suspect point of origin of a fire, ash and soot, along with porous materials which may contain excess accelerant, should be collected and stored in airtight containers such as new paint cans or wide-mouth glass jars, leaving an airspace to remove samples. Never use plastic containers to store fire scene evidence.
SC.912.N.1.1 Define a problem based on a specific body of knowledge, for example: biology, chemistry, physics, and earth/space science, and do the following:
Pose questions about the natural world, (Articulate the purpose of the investigation and identify the relevant scientific concepts).
Late one evening, 9-1-1 was activated when nearby residents noted a vehicle engulfed in flames behind a warehouse in the industrial park. Patrol officers responded and secured the potential crime scene while firefighters extinguished the flames.
After the fire was out, two young men were found bound with shoelaces and badly burnt in the trunk (ch. 16). Detectives and crime scene investigators were called to the scene (ch. 1). A thorough search of the area (ch. 2) revealed several shell casings near the burnt vehicle.
A rough sketch of the crime scene was completed showing that the vehicle was located in a field 50 feet west of a metal warehouse with two sets of tire tracks from the road west of the industrial park. The first pattern was consistent with the burnt vehicle and the second pattern was from an unidentified vehicle that entered and exited the scene. Police and fire vehicle all made entry from the parking lot of the metal warehouse (east of the crime scene) (ch. 3).
The medical examiner responded and transported the victims to perform autopsies. DNA was collected to identify the victims (ch. 15). The autopsies determined that the primary cause of death (ch. 6) was penetrating trauma from gunshot wounds. It was also determined that a substance identified as bleach (ch. 5) was present at patterned incisions of "CF" that were made prior to the time of death. Small, circular burn patterns were noted on both victims. Several bullet fragments were removed from the bodies and sent to forensics for ballistics analysis (ch. 9). The fibers of the shoelaces used to restrain the victims were also sent for analysis (ch. 13).
Detectives spoke with the victims' families who stated that they didn't have any enemies. The families were cooperative and allowed them to search the victim's computers. In doing so, threatening emails were found on the victim's computer that were signed "KJ" (ch. 18). Forensics specialists traced the emails to a physical address belonging to a man with the initials KJ.
A warrant was obtained to search KJ's house. Small amounts of blood were found at the scene, collected, and sent for DNA analysis (ch. 15). Soil samples taken from the suspect's shoes and vehicle were also collected and sent for analysis against those obtained from the fire crime scene (ch. 14). A knife, firearm, and bottle of bleach were found hidden in the home, both with fingerprints on them. These were sent to forensics for analysis (ch. 8).
