A hearing is scheduled for Wednesday to determine whether his 16-year-old brother, Devin Chapman, will stand trial as a juvenile or an adult.
Authorities allege that 21-year-old Donte Robinson, of Merriam, died after each of the brothers shot him Feb. 6 in a hotel parking lot in Overland Park. Another person was wounded in the shooting.
The defense said that Avrin Chapman only started shooting because he felt threatened and wanted to frighten people.
