BETHANY, Oklahoma - Investigators are following a new lead in the murder case of Carina Saunders, the young woman who was tortured and killed and her remains found in a duffle bag in Bethany.

Neighbors noticed Bethany Police searching in a field in Oklahoma City where a house stood just eight months ago,

"They asked us if we knew what went on over there," one neighbor told News 9.

Neighbors say 3500 S. Harvey used to house a lot of problems.

"All the time and all day long, even at night." 

Police reports show one dozen calls came from the address.

"It was a drug house."

On more than one occasion, the house turned into a crime scene; first in 2010, when a sex offender attempted to kill himself and again in 2011 when someone set fire to the place.

"They was probably doing drugs…and after it burnt, someone had wrote drug house," said the neighbor, who did not want to be identified.

In addition to drugs, neighbors say the house was a known place of prostitution and violence.

"There was this girl over the screaming saying help her, help her."

Neighbors say the house was demolished on October 13, 2011, the same day police uncovered Saunders' body in a duffle bag in a field in Bethany.

During the investigation, Police told News 9 Saunders' killers are tied to drug and human trafficking crimes similar to what neighbors say they witnessed at the house. Now, neighbors say police warned them that 3500 S. Harvey could once again be a crime scene if detectives can dig up enough evidence to prove it's the place Saunders was murdered.

Bethany Police say they are aggressively investigating Saunders' murder by working every lead, but  they could not say if investigators are looking at that specific location as the possible murder scene.

No one has been charged for the murder of Carina Saunders, but police have four people in custody on drug charges that they say are related to Saunders murder.
