Pottawatomie County officials say Akerman is a 2008 Drug Court graduate, which expunged his record of a minor drug charge.
Jewell was a student at East Central University with plans to teach art to children.
More than 250 people attended her funeral Thursday in Ada. Among them were college professors and disabled children she introduced to art.
Her brother said Jewell's friends collected money among themselves to buy an airplane ticket so he could be there.
Rock songs she loved were played at the funeral, and friends replicated her paintings and drawings on her coffin.
“Her funeral was unique, but so was she,” said her mother, Lida Beckman.
