A family continues to seek justice nearly a month after their loved one was killed in a hit-and-run accident.
Despite police releasing surveillance video from the night of the collision in Del City, no arrests have been made.
According to family and friends, David Harrison, 39, impacted many at the University of Central Oklahoma.
His colleagues honored him during a memorial ceremony.
For the past five years, Harrison, a UCO graduate himself encouraged future students to seek higher education.
“My brother had not finished high school, got his GED instead, and he walked them through the process of OK, this is where you are, this is where you need to be to start college,” said Nick Harrison, David’s brother.
After getting his masters, Harrison stayed at UCO and became the program manager of student support services.
“Basically, spending all his time doing outreach. Reaching out for communities particularly on the south side of the community,” said Harrison.
Nick said David’s personal and professional life were blossoming when suddenly it was unexpectedly cut short.
911 caller: There's a dude, I think he's been hit. He's on a bike. He's in the middle of the road, I don't know if he's breathing or not.
Video surveillance captured David riding his bicycle just before midnight on June 13.
“Trying to get back in shape, the bike was well lit up. The bike had every light you could imagine on it, so he was extremely visible at night,” said Harrison.
A truck is seen then heard out of the camera's line of site crashing into him.
“I know everyone makes mistakes, but the longer time goes by the more fault or anger that people feel,” said Harrison.
While an arrest won’t bring David back, his brother said someone needs to be held accountable.
I think that shook up a lot of people in the area. I think they'd like to see this person brought to justice so they're safe on their streets,” said Harrison.
Anyone with information about what happened, or the pickup truck is asked to contact police.
