Kris and Kelly volunteered as marathon runners to help find two missing runners.
Sabrina and Bosely worked in calling in evidence/clues to Charlie.
As the Angels gathered more evidence the piece of the puzzle came together. The two runners were kidnapped so Crofton duo could help kidnap the Arabian's daughter for ransom.
Kris and Kelly did not let this happen. They ran after the Crofton duo and captured them, while Bosely and Sabrina chased the van and cut them off and apprehened them. The kidnappers devulged where they were keeping the initial runners.
What kept me entertained is who the suspects were and who was their next victim and motive behind the kidnappings. Kelly and Kris showed their detective skills helped in the gathering of evidence while they were racing and reporting back to Bosely and Sabrina.
