CHEYENNE, Wyo. (AP) — Relatives of a 13-year-old Cheyenne boy who committed suicide say he was bullied in school.

However, not all family members are certain that is what prompted him to kill himself.

Authorities say Alexander Frye shot himself early Sunday morning near a railroad yard in Cheyenne. His body was found Tuesday.

Family members said they saw no warning signs that he was thinking of suicide.

His father, Bill Frye, said Alex was often bullied at his junior high school but he's not sure that was the reason for killing himself.

However, according to the Associated Press, stepsister Lauren Bard says that she believes his suicide was a direct result of being bullied at school.

School officials say they have no record of any bullying problems related to the boy.
