“I’m like, what’s going on? Why are these people on my lawn?

“So I opened the door and I asked them. And they’re like, ‘Oh, we forgot somebody. You gotta get out of your house.”

And he did.

Evergreen Park Police say the man had the 24 sticks of dynamite because 60 years ago, a friend was going to California and gave it to the man before he left.
