(CBS) Zapata County’s sheriff Sigifredo Gonzalez has told CBS News he has blood evidence from the lifevest of Tiffany Hartley, the wife of David Hartley, that supports her account of a pirate attack on a lake that straddles the Texas-Mexico border.
CBS News correspondent Don Teague reported on "The Early Show" this evidence is in addition to witness testimony that supports Tiffany Hartley’s story that her husband was shot in the head by pirates on Mexico side of Falcon Lake.
David Hartley is presumed dead, and officials on both the U.S. and Mexican sides of the lake are searching for his body.
Gonzalez told Teague he believes the Hartleys were attacked by enforcers of the Zeta drug cartel. The Hartleys, Gonzalez says, were innocent victims of a bloody drug war.
