Johnson is also a cousin of Trinette Lopez, according to family members. There was a history of dispute between the suspect and the victims, according to officials, who said Johnson had a prior criminal case involving the couple. The couple’s children told KHOU11 that their parents were high school sweethearts who had lived in their home since 2000. “Detective Mace worked hard to help bring our parents’ killer into custody,” Kristina and Jonathan Rayson said in a statement to KHOU 11.
