Officials of a Topeka school district say a teenager who died in a traffic accident had received his diploma just hours earlier.

The Topeka Capital-Journal reports Ronnie Graham was alone in his pickup truck when it struck a tree on a residential street around 3:30 a.m. Monday. He was pronounced dead at the scene.

Graham had just finished his senior year at Seaman High School in Topeka. The school held its graduation ceremony on Sunday afternoon at the Kansas Expocentre.

Seaman High School recently lost two other students to traffic accidents. Eighteen-year-old senior Emma Jo Pisocki and her father were killed in a head-on crash in Ottawa County in April, and 15-year-old Alayna Hutchinson died in February when the vehicle she was driving wrecked in Topeka.
