Their bodies were found inside their Brentwood home.
Austin police are being tight lipped about the investigation leaving Billie and Sidney Shelton's neighbors living in fear.
"I wish they were still sitting in the window and waving to me as I pulled in the driveway or walked by," said Marie Taylor, the Shetons' neighbor,
Their horrific loss haunts her everyday.
"I just go over and light two candles. I don't know why. It makes me feel a little bit better. I figure until they catch who did this maybe it's going up and letting them know I'm still thinking about them," Taylor said.
In mid-December, a nurse discovered Billie and Sidney Shelton's bodies in their home. Neighbors say since then, there's been a strong police presence but no arrests.
"I went the commanders meeting and he said all he could say was that something positive had happened in the case and that was about two weeks ago and since then I haven't heard anything," Taylor said.
In a statement, the Austin Police Department says, "As in all open homicide cases, is still a top priority for the homicide unit. Detectives continue making positive progress on identifying the individual or individuals responsible for the murders of Billie and Sidney Shelton."
It's a sentiment that Marie says has been shared with their neighborhood but it doesn't quell the fear.
"I'm not frustrated with police because I feel like they are being careful with the case. I'm scared to think whoever did this is running loose," she explains.
The neighborhood is working with the parks department to honor the Sheltons with a memorial bench at Brentwood Park. It costs $2,400. So far they've raised a third of the amount. If you want to help, you can contact Marie <a href=" Wabisabiholt@gmail.com">here</a>.
