A gruesome discovery of a human bone found Tuesday night in an empty southeast Austin field had APD investigators back at the scene Wednesday.
"We're looking at about a 9-acre tract so everything is divided into certain coordinates, so we're just methodically going over each of those coordinates so that we don't miss any evidence," said Cold Case Unit Sgt. Ron Lara.
That search led to more human remains.
"That's the big starting point is to identify what kind of bones you have and try to put the pieces together," said Homicide Sgt. Scott Ehlert.
He says the bones appear to come from one skeleton, although the remains were found in two different areas. Ehlert says they could have been moved by wild animals.
To find those answers detectives with APD's Homicide, Cold Case and the Missing Person's Unit canvassed the field for hours. Local and state search and rescue teams used dogs to find more evidence.
That crime scene is just across the street from the Ruff's home.
"Hopefully all of our neighbors will keep an eye out for each other and make sure nothing happens on our side of riverside," said Elizabeth Ruff. Her subdivision is a quiet one, she says, but the discovery across the street is grim enough to make her move.
"Very nervous and scared we have two young children and so we obviously don't want that to happen across from where we live," she said.
APD says it's unclear how long the bones have been in the field or if any foul play was involved.
"At this time the sex, age, race of this particular person is unknown," said Ehlert.
Its finding those answers, detectives in this case will focus on next.
"It could close an already open investigation or it could open an investigation of someone that is unaccounted for we just don't know," he said.
An autopsy will be done on the bones Thursday.
