Delvonte Tisdale, who is in 10th grade at North Mecklenburg High School, was last seen in Charlotte on Sunday.
The note was found on a homicide victim's body in the road in Milton, Mass., which is less than 10 miles south of Boston and about 15 hours away from Charlotte. The body of a young black man was found on Monday, which is also when the missing person report about Tisdale was filed.
The first name written on the note is barely legible but may be "Delvonte." The last name is Tisdale. The words "a lunch" are also scrawled on the note, which is signed and dated 10/19/2010.
Milton police said they're not entirely sure the name on the note is that of the victim. Fingerprint checks in criminal databases have proven ineffective in establishing identification.

At least six officers, both from Massachusetts and Charlotte were at Tisdale's home on Whitewood Trail in north Charlotte on Friday night.
The Milton police chief confirmed officers were at the house on Whitewood Trail in north Charlotte to collect hair, fingerprints and another DNA from the 16-year-old.
Charlotte-Mecklenburg police said they will assist the Massachusetts investigation.
Sgt. Richard Hammett said, "Helping them in anyway we can. Providing any documentation or another reference."
Tisdale's father told Eyewitness News on Friday that detectives have not confirmed to him whether the body is that of his son.
Eyewitness News spoke with a classmate of Tisdale's. She said he was new to North Mecklenburg High school and that he was very shy and devoted to ROTC. She also added he was incredibly polite and respectful.
Anyone who has seen Tisdale or has information about his whereabouts is asked to call police at 704-334-1600.
