Five months ago David Hartley was shot to death on the Mexican side of Falcon Lake while innocently jetskiing with his wife Tiffany, and notwithstanding the identification of four suspects no arrests have been made as reported by Kim Posey for KDVR. Last October Mexican officials identified two brothers -- Juan Pedro and Jose Manuel Zaldivar Farias -- who are alleged members of Los Zetas as suspects in Hartley's murder.
