LINCOLN, Neb. (AP) — Prosecutors say hit-and-run charges won’t be filed because there’s no evidence a driver knew his car had hit a motorcyclist and dragged the body of a Lincoln man for more than two miles in January.

Lancaster County Sheriff Terry Wagner said Monday that the driver didn’t know the bump he noticed was the body of 38-year-old Gabe Wilken, who’d already crashed. County Attorney Joe Kelly says a hit-and-run charge would require prosecutors to show the driver knew he’d hit someone.

Investigators don’t know whether Wilken was alive when he was struck by the driver’s sedan after Wilken crashed just after 7 p.m. on Jan. 16. The car driver told investigators he didn’t come forward because he didn’t know he’d hit Wilken and had heard deputies were looking for a pickup.
