The husband of a slain Missouri woman is still searching for his wife's murderer — and he doesn't want anyone to forget it.

As part of the ongoing investigation, Jeff Roberts has decided to post a police sketch of the suspected killer on several billboards running along a busy town highway, according to FOX4KC.com.

Cara Roberts was found dead in her Harrisonville home last November and her husband is now hoping the billboards may help to finally solve the case.

"That's someone that was seen walking throughout the neighborhood," Jeff Roberts told the station. "Around 4, 4:30 p.m. Black hat, black coat. Walking really fast. Hands shoved deep in his pockets."

The town's commuters will be able to see the billboards, which will run along Highway 71 in Harrisonville, Mo., beginning as early as Wednesday.
