Michael Garza, 46, of Hispanic ethnicity, died on June 2, 2015, in Houston, Texas. His death was first reported as from natural causes, but later inquiry tied him to a murder conspiracy in which he and his lover, Chacey Poynter, plotted the killing of Chacey’s husband, Robert Poynter.

Investigators grew suspicious after learning the couple were divorcing and that Chacey was having an affair with Garza. Garza ultimately shot Robert in the head with a shotgun; Chacey Poynter was convicted of arranging the killing and received a life sentence, and Michael Garza turned himself in and was given a 99-year prison term.

The case received national attention and was profiled on 48 Hours on ID. Does anyone have additional details about the investigation or knew the Poynter or Garza families?
