A Douglas County sheriff’s detective is working to bring some good from an accident that killed a Nebraska man in November 2010.

Twenty-three-year-old Zachary Harrison, formerly of Hutchinson, is serving nearly seven years in prison for stealing a truck on the University of Kansas campus and later rear-ending a car 21-year-old Cameron Freeman was riding in. Freeman, of Lincoln, Neb., died in the crash on U.S. 59.

In response, Freeman’s parents started the Cameron Effect, a Web-based effort that asks people to commit seven acts of kindness.

Detective Jay Armbrister responded to the Freemans’ efforts by giving presentations about the accident to try and prevent similar tragedies. The Lawrence Journal-World reports  he’s also befriended Harrison, who will join in the speeches when he’s released from prison.
