Neighbors never heard the jackhammer needed to bust up the concrete flooring to initially get a hole big enough for burying the body? Did she hire someone to do the deed of actual burying? She doesn’t look too hand with heavy equipment needed and carrying in bags of cement.

Sheriff’s Det. Tim Austin has said he and another detective opened the door to Keene’s basement, where a mass of hardened concrete was discovered.
