Nathan Joseph, 31, of Orlando, Florida, was killed on February 26, 2015. He was riding his motorcycle on the entrance ramp from State Road 408 to Interstate 4 when he was fatally shot. The incident was first treated as a crash but was later reclassified as a homicide after investigators determined he had suffered gunshot wounds.

Joseph left behind a 10-year-old son and a baby on the way. On July 30, 2018, Orlando police announced arrests in the case: Ryan Kegler, 28, Jhoan Cadavid, 29, and Bret Badalucca, 37, were charged with first-degree murder and held in county jails. Authorities did not disclose the specific evidence that led to those arrests.

What can readers who remember that stretch of I-4 or who knew Nathan share that might help fill in gaps about his last hours?
