New Tribes Mission (NTM) has concluded, based on multiple guerrilla testimonies, that three American missionaries kidnapped 8 years ago in Panama were shot by their captors three years later as Colombian troops closed in. While the remains of Dave Mankins, Rick Tenenoff and Mark Rich may never be found, NTM has exhausted all leads in the case. Both the mission and the hostages' families are satisfied that the men are dead. "It's God's time for closure," said Dan Germann, NTM vice chairman. "The years of tears and anxiety for our dear brothers have ended."
