NEW RIVER, AZ - Authorities say a 49-year-old man has suffered a severe leg injury after stepping on an explosive outside a home in New River, north of Phoenix Monday night.
Officials said one of the man's legs was completely blown off, the other has serious injuries.
The man was flown to the hospital in critical condition. Officials told ABC15 he was helping a couple, who was renting the house, move out.
At this time, it is unknown what type of explosive device he stepped on because authorities locked down the scene Monday night, even for investigators.
No one's been allowed onto the property since the explosion happened. They're concerned they'll find even more explosives on the property.
The former homeowner, Chuck Byers, has quite a history with keeping explosives and chemicals at this house. ABC15 searched our news archive and we've covered this house before, when it was owned by Byers, back in 1998.
At that time, his family ran a munitions company on the property and explosives and boxes of chemicals were stored there.
Neighbors protested when the Bureau of Alcohol, Tobacco, Firearms and Explosives planned to blow up the explosives or burn them. They were worried for their own safety.
Maricopa County Sheriff Joe Arpaio says, at this time, they are not connecting Byers to Monday's explosion.
He points out it's been years since he has lived at this home.
But, Tuesday morning, as soon as the sun comes out, MCSO will continue their investigation.
Once the bomb squad is able to get onto that property, we'll know much more about the explosion.
