CHARLOTTE, N.C. — The father of a North Carolina teen whose mutilated body was found on a suburban Boston street said Tuesday he was struggling with the boy’s death amid reports authorities were investigating whether the student might have fallen from an aircraft’s wheel well.

Anthony Tisdale said he last saw his son Delvonte on Nov. 14 when they did yard work together and the family had pizza for dinner. When the 16-year-old failed to return from school the following day, the family called police. The boy’s remains were found last week in Milton, Mass., several days after he was reported missing.

Other relatives described the boy as being unhappy in North Carolina and having missed Baltimore, a city he had lived in until he was 13.

In Boston, a Logan International Airport spokesman said investigators requested flight path information and were looking into the “remote” possibility Delvonte may have fallen from a plane’s landing-gear well.

Anthony Tisdale said at a news conference Tuesday in Charlotte that investigators haven’t told his family anything about an airplane and he has no idea how his son ended up near Boston.

Delvonte Tisdale was a member of the Air Force ROTC program at Charlotte’s North Mecklenburg High School. His father said the family had moved from Greensboro to Charlotte in the summer just so the teen could join that program.

Tisdale said his son was happy in Charlotte and loved high school.

“Being here such a short time and losing my son is very difficult,” Anthony Tisdale said, wiping away tears as he spoke with reporters Tuesday. “My son was a hardworking young man, he didn’t frequent the streets … he spent time with his family.”

The teen’s brother told The Associated Press by telephone on Tuesday that the teenager was unhappy in North Carolina and had never wanted to leave Baltimore, where he had lived earlier.
