Lyle Stevik (c. 1976 – September 16, 2001) was the alias used by an American man who, in 2001, died by suicide inside a motel room in Amanda Park, Washington.

Although his body was quickly discovered, and fingerprints, DNA and dental information collected and recorded, there were no matches in any databases and the man's identity remained unknown until 2018.

Finding a cluster of matches of relatives, perhaps two to three generations removed, in New Mexico, they were eventually finally able to locate members of his birth family.

[5][6] The man who identified himself as "Lyle Stevik" checked into the Quinault Inn, a motel in Amanda Park, Washington, on Friday, September 14, 2001, after arriving in the area by bus.

[8] When registering for his room, he entered his alias and provided a false home address, eventually discovered to belong to a Best Western hotel in Meridian, Idaho.

[4] Stevik was reportedly seen walking back and forth at the side of a highway near the Quinault Inn, but it is uncertain if this was before or after he registered and paid for his room.

[4] Located by techniques of genetic genealogy performed by staff and volunteers of the DNA Doe Project in 2018, the man's family had been unaware of his suicide.

[4][8] Upon discovery of the body, police reported that Stevik had closed the blinds in the room and lined the closet in which he hanged himself with pillows.

The coroner estimated this weight difference after noting that the size of the man's jeans was fairly large in comparison to his body.

[7] Because Stevik was deceased for only a short time before his body was found, examiners readily obtained his fingerprints, dental characteristics and DNA.

It is believed that he came to the area from Aberdeen or Port Angeles, locations from which buses daily traveled to Amanda Park.
