This CSI screencap contains
yanazunguka mlango, bastola, mlango unaozunguka, and revolver.
There might also be
suti biashara, biashara suti, taasisi ya adhabu, adhabu kituo, taasisi ya kuurekebisha, kituo kuurekebisha, fireplace, makaa, wazi fireplace, meko, and meko wazi.
This was one of my inayopendelewa parts of the episode, namely because the trials our CSIs go through are rarely ever brought up long after they happen.
