Derek Foronda, 25, of Upland, California, was found shot multiple times on a sidewalk in the 500 block of North Fairwood Way, between West Winn Drive and West Arrow Highway, on March 11, 2017. The death was ruled a fatal shooting and prompted an immediate investigation by the Upland Police Department.

Investigators arrested 25-year-old Anthony Christopher Musselman after a standoff at a residence in Colton. Musselman was charged with first-degree murder and possession of a firearm by a felon. Records presented at trial established that Musselman and Foronda knew each other from high school and were friends; no clear motive for the shooting was disclosed.

A jury found Musselman guilty of first-degree murder and possession of a firearm by a felon, with firearm enhancements, and he received an aggregate sentence of 53 years to life in prison. Did anyone who knew Derek or saw him in Upland around March 11, 2017, notice anything that might help fill gaps in what led to the shooting?
