AUSTIN, Texas (CBS/AP) U.S. and Mexican authorities say Commander Rolando Flores, a Mexican state police officer investigating the reported shooting of American tourist David Hartley by pirates on Falcon Lake on the U.S.-Mexico border, has been killed.

Spokesperson for the Tamaulipas state prosecutor's office Ruben Rios says Flores, the head of state investigators in the border city of Ciudad Miguel Aleman, has been killed.

According to Texas state Representative Aaron Peña's twitter feed, Flores' severed head was delivered to the Mexican military.

Flores was investigating the disappearance of American David Hartley. Hartley's wife, Tiffany, says she and her husband were attacked by pirates on Falcon Lake on Sept. 30, while they were returning to the United States from Mexico on Jet Skis. Hartley was shot and presumably fell into the lake.

Rios says his killing was unrelated to the investigation, but U.S. authorities have said threats of violence from drug gangs who control much of the area has hampered the search for Hartley's body.
