Homicide investigators and police recruits sifted yesterday through underbrush and debris in the woods where an Old Mill High student was found stabbed to death Saturday.
"We are hoping the killer dropped something," said Anne Arundel County Detective Shelly Madison.
The nude body of Lisa Kathleen Haenel, 14, was discovered about 9 a.m. Saturday lying face down in a ravine near the intersection of Shetlands Lane and Century Towne Road, next to the rusted-out shell of a car. The girl had been missing since Friday morning.
After following up on several leads and questioning possible witnesses, police have worked up a composite sketch of a man they believe could be a witness or have information about the crime. He was seen by several people in the area of Shetlands Lane and Century Towne Road the day before the slaying.
He is white, 19 to 20 years old and 6 feet tall with a thin build and short blond hair, and he was wearing a black knee-length coat, a black baseball cap and baggy pants.
Detective Shelly Madison said that since the man was seen in the area Thursday morning, he might also have been there Friday morning around the time Lisa was killed. Investigators would like to talk with him.
Meanwhile, Sgt. Robert Jaschik said, investigators are awaiting the results of lab tests to determine if the girl had been sexually assaulted.
Police crawled through the woods on hands and knees yesterday as they searched. But they said later it was difficult to separate what might have belonged to the killer from what passers-by left behind.
"There is all kinds of stuff down there, including an old refrigerator," Detective Madison said.
Sergeant Jaschik said detectives have questioned several people in the case. Police also distributed more fliers with a picture of Lisa and a description of the jeans, sweat shirt, tennis shoes and Old Mill band jacket she was wearing when she was last seen alive.
"We have picked up some information about the crime from calls that have come in as a result of the flier," Sergeant Jaschik said. "And we will be checking those out."
Anyone with information about the crime is asked to call 222-3461 or 222-8050.
