Silent Witness: Finding Rachel (Part 1 of 2)

When Rachel Harrington's bones are found in Zambia, her father asks the team to investigate. He doesn't believe the local police's claim that Rachel was killed by wild animals - she had been accusing the government of a health cover-up, and an initial examination shows evidence of multiple stab wounds. But as the team investigates further, they discover the government weren't the only ones to have been rubbed up the wrong way by Rachel.
