A deadly crash between two semis happened the evening of June 22 on the New Jersey Turnpike in Gloucester County.
What police say: According to dash cam video and witness accounts, 41-year-old Joseph M. Nyandwaro of Texas intentionally hit another big rig, ramming it into a barrier. He then drove off while laughing, police said.
- The second semi, driven by 40-year-old Osman Aden from Minnesota, hit the concrete barrier and crossed the roadway before slamming into trees. Aden died at the scene.
- Video from inside Nyandwaro's truck showed him laughing right after the crash, according to NJ.com.
After the wreck: Nyandwaro left the Turnpike at Interchange 2 nearby, then re-entered some 90 minutes later at another exit. Police found his truck with damage and paint matching Aden's rig, along with signs someone tried to cover up evidence using duct tape and cleaner.
Nyandwaro turned himself in on July 1. He's being held on charges including vehicular homicide, leaving the scene of a fatal crash, and tampering with evidence. No court date was listed in records as of Wednesday.
