KSP: Suspects in Nelson Co. double murder driving black Impala

LOUISVILLE, Ky. (WDRB) -- It has been almost nine months since a Nelson County mother and daughter were murdered in their home, and police remain focused on one key piece of missing evidence.Investigators still believe a black Chevy Impala is the key to solving the case.

In the week after Kathy and Samantha Netherland were murdered, police released a surveillance photo of a late model black Chevy Impala. They say the killer or killers were inside.

Tips have come in, but so far nothing has led to a suspect.

"We've checked several hundred -- into the thousands -- black Impalas in Kentucky and even out of state," said Kentucky State Trooper Jeff Gregory.

But police say a database shows there are more than 20,000 black Chevy Impalas in the state. They say the one in the photo is from 2012 or 2013.

In the last several months, Kathy's sister, Stacey Hibbard estimates she's sent police 50 to 100 plates from cars that may fit the description.

"You don't ever pass a black Impala that it doesn't catch your eye," Hibbard said.

The Netherlands were murdered in their home just outside Bardstown on April 21st. Samantha was a sophomore in high school and her mom was a special education teacher.

We asked police how they determine whether a specific black Impala was involved in the murders.

"We try to check if they'd have any relation, any reason to be in the Bardstown area. Different things we have on the case, Some of them that I can't give up right now," Gregory said.

Police say with time tips have slowed so they are once again asking the public to call if they recognize the car.

"We've never hidden the fact that the black Impala, we feel like, holds the keys to solving this case and we've worked very hard to discover where that car is, and unfortunately we haven't been able to come up with it yet," Gregory said.

Anyone with information is asked to call Kentucky State Police at 270-766-5078.
