Shohn Richard Cowen Jr., 20, of Mesquite, Texas, was one of two people found shot to death at Shands Park on July 7, 2017. The victims were discovered about 11:15 p.m., and authorities have said the shooting arose from an ongoing dispute among the individuals involved rather than a random act.

An 18-year-old, Alberto Martinez, was arrested and charged with two counts of attempted capital murder and one count of capital murder in connection with the incident. The investigation continued as police followed leads.

Shohn’s family and the Mesquite community mourned his death; his obituary ran in the Dallas Morning News. Does anyone have information about Shohn’s activities that night or who else might assist investigators?
