A Dearborn Heights man being held as a hostage for nearly six months in Yemen has been released. Sam Farran, a 54-year-old security consultant from Dearborn Heights, was one of two Americans being held. The other was Scott Darden, a 45-year-old working for a New Orleans logistics firm. They have been released and sent to Oman. Darden and Farran had been held since March 27 after being detained by rebels fighting government forces in the Yemeni capital of Sana’a.
