According to this story
on KRGV in Texas, a fisherman was hit by a stray bullet on the same lake where David Hartley of Colorado was murdered
while jet skiing with his wife Tiffany. David's body and the jet ski were never found, and the investigation into his murder was marred by the decapitation of one of the investigators
. As of late Saturday, deputies were still searching for the shooter on the assumption that the incident was an accident: "We believe the shooter might not know that he shot somebody, but we're narrowing down the property owners in that area, close to Los Lobos Park and trying to reach out to them and see who was out there in that area doing target practicing or hunting," said Zapata County Sheriff's Department Captain Aaron Sanchez.
