Parker Smith was 21 when he and a friend, Andrew Remillard, were fatally shot while seated in a parked vehicle in Phoenix on November 27, 2017. Their deaths came at the start of what investigators later tied to a series of violent attacks across the metropolitan area over the following weeks.

Police linked the killings to Cleophus Cooksey Jr., who was found at the scene when his mother, Rene Cooksey, and stepfather, Edward Nunn, were discovered shot to death in their apartment on December 17, 2017. Officers reported finding a blood-covered Cooksey and recovered items in the residence, including a handgun taken from a security guard Cooksey had been accused of killing and keys connected to another victim. Ballistic testing was used to connect one weapon to multiple scenes.

Many details about motive remain unclear. If anyone knew Parker Smith, Andrew Remillard, or saw suspicious activity in Phoenix between late November and mid-December 2017, please share what was observed with the investigators handling the case.
