Gregory Franklin Jr., 41, was found dead in his Corona, California home on June 18, 2018, having suffered multiple gunshot wounds. Investigators treated the death as a targeted attack; there were reported to be no signs of forced entry, which led police to consider that Gregory may have known his assailant and to explore motives including personal disputes or possible criminal connections.

Authorities identified several persons of interest in the months following the killing and pursued forensic leads. A suspect was later arrested after DNA evidence was reported to link them to the scene, and prosecutors brought charges including first-degree murder and possession of an illegal firearm. The family endured a prolonged investigation before that arrest was announced.

What, if anything, did neighbors or acquaintances notice in the days before June 18, 2018, that might help fill gaps in the timeline?
