GILBERT, Ariz. (AP) — Investigators said Thursday they found a half dozen grenades among the military munitions in a suburban Phoenix home where a former Marine with ties to neo-Nazi groups shot four people and then took his own life.
U.S. Bureau of Alcohol, Tobacco, Firearms and Explosives agent Tom Mangan said the agency is tracing the serial numbers of six 40 mm projectile grenades discovered in Jason Todd Ready’s house.
The explosives were strictly military-issue and should not have been in a residence, Mangan said. Officials from Luke Air Force Base took the grenades and destroyed them.
Warren Jones, manager of an Army surplus store in Phoenix, said the type of grenade authorities found is not available at any store.
“It clearly had to be acquired on the black market,” Jones said. “It’s not something they can just meet with somebody and purchase.”
Jones said civilians with a special license can obtain the devices, however, there is usually paperwork required by the ATF.
Ready was the founder of a group called the U.S. Border Guard and led groups of heavily armed, camouflaged civilians into the desert to look for illegal immigrants.
Gilbert police say the four others killed in Wednesday’s shootings include 16-month-old Lily Lynn Mederos, 23-year-old Amber Nieve Mederos, 38-year-old Lisa Lynn Mederos and 24-year-old Jim Franklin Hiott.
Lisa Mederos is believed to be Ready’s girlfriend.
