Crane topples onto 2 homes in River Vale, N.J.

A truck carrying a boom crane tipped over in River Vale, New Jersey, on Thursday, causing the crane to land on two houses, slicing one in half.

It happened at around 10:20 a.m. at a home on Sunnyhill Terrace. 

Though one home suffered significant damage, no one was injured.

Fire officials said the crane flipped over after one of the truck legs landed on top of an underground concrete seepage tank that no one was aware of. According to online information, a seepage tank carries away wastewater.

"This truck was working on cutting trees and, essentially, its outriggers came out and one of the outriggers landed on that tank underground that they could not see, caused the crane to tip over and the boom to crash onto the home," said Lt. Vasili Karalewich, of the River Vale Fire Department.

Dina Demayo said she had hired the crew to take down a rotting tree, and she was inside her house when she heard the crew screaming. Demayo said she grabbed her cat and ran for her life.

"And I started running and all of a sudden I heard bam, and I looked out the side of my window and I thought it was a tree, but it wasn't a tree. It was a crane," she said.

The crane literally split her garage in half.

"The crane went right through my garage and then I saw the crane was sideways. I didn't realize it was sideways," Demayo said.

She said the crane also landed on the bedroom of her neighbor's house.

"They told me there was actually a person who was supposed to sleep in that room, but last night, she called someone and said she was going to be going somewhere else. But she would have been in that room," Demayo said.

Demayo said Downes Tree Service told her its insurance is picking up repair costs for her house, which she had planned on selling, and her neighbor's home.

CBS News New York reached out to the tree company and was told no one would be commenting.

The River Vale Fire Department said it had three wreckers on scene trying to stabilize the truck and that the boom would have to be cut in half to remove it.

Fire officials said they detected no gas leaks in the area and that no one lost power.
