HYDE PARK, N.Y. -- Reservoir Road remained the focus for state police Saturday in Hyde Park. Troopers and police search dogs combed the area looking for evidence that could help them make an arrest in the Laurie Ferguson homicide investigation.

"We're going to keep working this until we find the person responsible for committing this crime," said New York State Police Captain Scott Brown.

The 67-year-old Ferguson was found stabbed to death in her nearby trailer home Thanksgiving evening. The victim's car stolen from her home police say was found on Reservoir Road.

Earlier in the day police, released this sketch. It's of a man who they say was spotted near where the car apparently was ditched. He's described as being 5-foot-10 or taller, with a full head of dark hair and a bushy, neatly trimmed beard.

At this time, police say the individual in the sketch is not a suspect. Just someone of interest they'd like to locate to find out what he knows, if anything, about the death of Laurie Ferguson.

"The vehicle is being processed for possible evidence. And being that this is a continuing homicide investigation, that can prove crucial," said Brown.

Meanwhile, at the Mobile Manor Trailer Park where Ferguson lived, neighbors say they're feeling a little uneasy knowing a killer remains at large.

"I live here and it scares me," said resident Gordon Rozelle.
