Authorities find explosives, grenades in Pinal County home
FLORENCE, Ariz. -- Pinal County authorities said they found explosive devices and grenades in a San Tan Valley home while investigating a report of an assault.
The county Sheriff's Office received a call Saturday from a Washington state man who said his mother had been involved in an argument with another son.
The man claimed that 51-year-old Wesley Boles had put a gun to his mother's head.
A criminal history check showed Boles was a prohibited possessor of a firearm because he has two prior felony convictions.
Detectives and SWAT team members served a search warrant on the residence. They reported finding 28 firearms, two 37 mm rocket-propelled grenades, five homemade explosive devices, a detonator and thousands of rounds of ammunition.
Boles has been booked into jail for assault and possessing firearms and ammunition.
