Elizabeth Tinkham pulled back the board she used to cover a sinkhole in her yard, to show us just how deep it was. 

Just one foot across, it's at least 10 feet deep. And Tinkham believes it stretches to the other side of her property.

It opened up just as her teenage son was mowing the lawn Thursday evening.

"He pulled up to the front of the fence," Tinkham said. "He backed up and the tire got stuck.  It's very frustrating and it's very heart wrenching.  Because I have three children. What would've happened if my 3 year old went running back here?"

Tinkham said she already has a claim filed with Citizens. In fact, she tells us she did that two years ago. She said Citizens sent out a contractor to test the area and has documentation to confirm they found sinkhole activity on the property at that time.

"That was signed by the engineer on the November 23, 2011 and filed with the clerk on the 30th," Tinkham said.

But instead of taking care of the problem, Tinkham says Citizens is fighting the claim. The two parties have gone back and forth more than a year, despite what Tinkham says are obvious signs of a disaster waiting to happen.

"This goes all the way up to my son's bedroom," said Tinkham.  "And there's erosion right around the water main right here. I mean, how much more blatant can this stuff be. They say they are going to wait until our trial. Next year. Next year. I don't have until next year."

We called Citizens to find out if this latest development would change Tinkham's claim. While they couldn't comment specifically on the case because it's in litigation, a spokesperson told us they are sending a team out to the property to assess the damage.
