Mobile Forensics

Scenario
It is midnight on a Friday night, it is just beginning to
sprinkle with rain.
You are the first officer at the scene of a homicide
where the victim has been shot several times by one
shooter. Witnesses have pointed out a cell phone
that they saw the suspect using and threw away as
he left the scene.
It is clear that the device is still on.

Considerations
 Airplane mode?
 Shielding?
 Signal Jammer?
 Dangers of leaving it on and transporting the device
 Remove SIM card?
