INDEPENDENCE, Ky. -- Authorities in California arrested a former Marine from Northern Kentucky Tuesday after finding an explosive in his luggage at an airport.
Gregory Salyer, 23, of Independence, Kentucky, was arrested at John Wayne Airport after officials say they found three military artillery fuses, a sting ball grenade, a small knife and about 300 steroid and Adderall pills in his checked bag.
Salyer was charged with one count of placing a destructive device in checked baggage, two counts of possession of a controlled substance, one count of receiving stolen property and carrying a switch-blade knife.
Transportation Security Administration agents say they saw something suspicious while Salyer was trying to board a plane and a local bomb squad responded to the scene.
The airplane and gate were evacuated after the discovery and the military took possession of the grenade and fuses, which Salyer was not authorized to have. He was last stationed in Twentynine Palms Marine Base.
Salyer was recently discharged from the Marines, and may have been heading home when he was arrested.
A neighbor of his family’s Independence home, who did not want to be identified, said Salyer is a good man.
"I think it was just something stupid,” the neighbor said. “Kid bringing some souvenirs home…he didn't think about it."
Prosecutors say Salyer is being held on $500,000 bail.
It was not immediately clear whether Salyer had an attorney.
