An Oregon man charged in the Oct. 16 death of a 21-year-old barista unwittingly left a trail of evidence as police followed him in the hours before his arrest, court documents show.

Over the weekend, ABC News spent time with Clint as he returned to his apartment and talked to a reporter by the impromptu memorial, which included candles, flowers, and a placard signed by family and friends that had been tacked up next to his door.

Whitney Heichel, the 21-year-old Gresham woman who was found dead last week, was sexually assaulted before she was murdered, court documents said.

Whitney Heichel vanished on her way to work Tuesday, triggering a search effort that ended late Friday with the discovery of her body on Larch Mountain east of Gresham.

It remained unclear Saturday what information led police to a neighbor and acquaintance who quickly emerged as a suspect in Whitney Heichel's death last week.

Searchers have located the remains of missing woman Whitney Heichel, and police have arrested a man suspected in her death. Heichel had not been seen since she left for work at a Starbucks outlet on Tuesday morning.
